[@Necropheliac]

I noticed when I converted some of my masters to mp3 the mp3 file sounded more scratchy bright than the same track with a 24 bit wav. It was noticeably different in the high frequencies. After some trial and error I eventually fixed the problem by applying a high cut filter to the inaudible high frequencies in the track. From this I surmised that these inaudible frequencies were being mapped to audible frequencies by the mp3 codec. I’m not saying that high definition audio is superior because it handles frequencies, but rather curious why this happens? Why does the mp3 dithering not handle the mapping more gracefully?

[@olhoTron]

Probably a bug in the mp3 encoder, maybe they are resampling the audio using a naive averaging algorithm

[@joejurneke9576]

Exactly correct. As a digital signal processing expert, I deal with this situation every day. With modern antialiasing filtering, reconstruction algorithms etc higher sample rates does not matter. 16 bit vs 24 bit resolution only changes the effective signal to noise ratio the systems can support. 16 bit supports 65535 slicing levels. 24 bit supports 16,777,216 slicing levels. Hence 16 bit supports 96 dB SNR where 24 bit supports a SNR OF 144 dB.

[@gurratell7326]

And then add noise shaping to that dither and the effective SNR of 16bit goes up to 120dB.

[@trollakhinmemeborn3278]

I will say though, one advantage of using higher bit depths is that it can save a take if you realize (too late) that one of the mics wasn't amp'd enough, and you can't take another take, having that lower noise floor, from what I've seen anyways, allows you to really amplify the signal in the mix without getting any noticeable noise. But admittedly, that is a pretty specific usage, that happens because of user error to begin with. (edit) the whole thing about audio being better when treated less preciously is precisely why people seem to prefer vinyls & tape, even in today's day and age, I work in digital graphic arts, and it's really the same, often in digital artworks you want to add 'noise' and irregularities into artwork, that usually always makes it pop more, and gives it character

[@JustinColletti]

Yeah, if you were to record a sensitive source at something crazy low, like -60dBFS or lower in 16 bit you could MAYBE run into noise floor issues. That’s an insanely low record level, so it’s unlikely to be a problem very often. But because of this unlikely possibility it is definitely a best practice to do 24bit when recording instead. That seems reasonable to me. But even 24 bit is actually overkill for that, because none of your analog front end can use 24bit’s 144dB of dynamic range. 20 bit probably would have worked just as well for this purpose, because that’s about where really nice analog gear is going to max out for keeping the noise floor down, but it’s no big deal either way. For consumer audio though? No way! :-) Even 16bit is probably overkill for all practical purposes. Hope that makes sense! -Justin

[@FloatingOnAZephyr]

It's worth repeating, as you mention, that capture and delivery are very different things. For example, Zoom just released a sound recorder that records 32-bit float (the F2 lavalier recorder). The huge benefit of that is that it's impossible to blow out the recording as it doesn't peak at 0dB, and levels don't need to be set. You just hit record and you're golden. Once the sound is captured, that 32-bit float just becomes 32-bit bloat (you heard me). Recording headroom is just recording headroom. The end listener doesn't need to hear the empty headroom, and won't benefit one iota from doing so.

[@OKvalosound]

Very good summary, I totally agree!👍 Especially concerning our golden time of audio quality! Unfortunately I can't imagine what we can expect from future developments🤔. The great leaps in improving audio quality are behind us. But luckily we are now able to concentrate fully in our creativity without be concerned about quality - even at home! I remember recording on noisy tapes in the 80ies. Everything today was science fiction at those times (a DAW running on an tablet!!!)

[@alee3875]

No, people always use Nyquist-Shannon sampling theorem to say you only need to sample twice the highest frequency you want to record i.e. in Audio you only need 40kHz. But did not understand the whole theorem. The theorem also said you need to multiple every sample to a infinite function call sinc function to be able to recover the same wave form. The important word is "infinite function". It is impossible to calculate infinite function because that would take infinite time. So you always need to stop some where just like when you use Pi. Higher sample frequency will make calculation many times near to "infinite function". So same DAC chip with same computing power suppose to have easier time with higher sample rate in theory.

[@livetorock1844]

Thank you for interjecting some reason and science into this area. On a somewhat related note, I've noticed that many people equate "pristine" audio with detail. But audio that is very revealing of detail is not necessarily perceived as musical or all that pleasing to the ear. (I came across at least one blind study that arrived at the same conclusion).

[@latheofheaven1017]

True. Witness the love of the sound of vinyl - which has a smaller signal to noise ratio than 16bit digital audio, has more stereo crosstalk, and changes its frequency response and harmonic distortion characteristics according to how far towards the centre of the disc the needle happens to be. Not pristine at all by comparison to digital audio, but people love it.

[@LeffeAndersson]

I always record in 48 kHz/24 for two simple reasons. 1. All my gear supports 48 kHz, so whatever interface I choose to use it’s working with 48 kHz. 2. If the recordings will be used in a video I will have a perfect sample match. If you use 44.1 kHz with a 24 FPS video each frame will have 1837,5 samples, so if I cut both the video & audio when the grid in PT is set to frame the cut will be between two samples. This is avoided with 48 kHz. So, that’s my approach, I use 48 kHz for practical reasons, not audible.

[@SonicScoop]

Valid reasons for sure!

Same for me, I work in 48 for practical reasons, the TV/media business works with this sampling rate and expect you deliver your tracks/stems in 48k/24b.

[@matthewv789]

Yeah, and here are two conceptual things that are often misunderstood: 1. There are no stair steps. Digital audio is entirely smooth, continuous, and analog once it goes through the low-pass filter. That’s the whole point of the filter, is it turns everything at the upper frequencies into pure, smooth sine waves, filtering out all the squareness (which are just the upper partials). 2. It only takes two samples to accurately reconstruct any given sine wave at or below that frequency, perfectly in terms of frequency, amplitude, and phase. Sine waves have a particular shape such that you can mathematically reconstruct the whole thing just from the two samples.

[@SonicScoop]

Bingo! You are exactly right. Either a given frequency can be reproduced perfectly at a given sample rate (minus some noise, which is determined by the bit depth) or it can’t be reproduced at all. It’s a bit of an all-or-nothing affair. Thanks for the comment, Justin

[@matthewv789]

[@OKvalosound]

@ReaktorLeak Thank you for this analogy👍

[@danieljung2810]

What's misunderstood is anti aliasing/mirror effect requiring low pass filters which he mentions in this video, but doesn't go through much detail. If you pay attention he is staying that the mastering process could benefit for higher frequency rate on the recoding session in terms of having a easier time filtering high frequo based on equipment used and recording in higher bit rate gives you much more headroom so there is less likely clipping while recording. I think the majority of people missed the boat on this. In other words, if you actually record in a higher bit rate with higher frequency rates where higher frequency noise with high enough amplitudes could enter the mix and a higher chance of clipping, it would make a difference.

[@euphoricmonkey8409]

Great video. I’ve had the same concerns myself and you properly articulated why. The best ever hifi upgrade I did was buy a Nord One Up amp. This was a game changer for my PMC OB1s speakers. I have heard differences between formats but not in ABX tests. What I mean is the Linn 96/24 for example sound great but think the real reason is the the audience for these are people who care about music and the producers bother to mix the tracks well in the studio. i.e. don’t dynamically compress the music. Place instrument well etc. It’s not the format it’s the production. Madonna immaculate conception on cd sound just as “interesting” and alive as any 96/24 recording do.

So, Justin, I see you've changed back to another JZ Mic which looks like the V67! Nice choice! As for the topic, I really enjoyed listening to this and your perspective. I have to admit that I was somewhat of a numbers-fan and thought that bigger meant better. However, after listening to you it made sense to me in that you really won't hear the difference on the listening end of the sound. And I'm convinced that you need some really high-quality headphones to even attempt it....if you can. I've tried and didn't hear a difference. I am going to have to do some really close comparisons when I do get a chance to see if I can capture the differences between the two resolutions. Again, thanks for this video Justin!

[@georgecorg783]

I'd like to point out a big missconception here: quality matters if it's higher or lower sample rate, the lower sample rate the lower the quality that is a scientific fact judging by how the quantization works. The big point that all seem to miss is that beyond 44.1kHz one would not be able to tell the difference and basically is pointless to have so much storage space spent for nothing.

[@stevesstuff1450]

Exactly! 22K is pipe dream for most people; most adults hear in the 10 - 16K range, dependant on age, and the music doesn't sound 'different' just because we've lost a few KHz here and there! If cymbals still zing, and ting like they should, then excessive high frequency recording is a waste.... I know in some circumstances that there are higher frequencies that work with others to give a certain order of distortion that resonate well (certain harmonics) that if missing would destroy the feel of the music and maybe even notes being played, but these are all recorded within the 'lowly' 16/44.1 redbook solution, so it's not an issue! As you say, storage space for needlessly high 'resolution' files is just pointless! I love good old analogue, but I also love my (well recorded/mastered) CD's... :-)

I remember converting the black album cd in the '00 to various kbps mp3, starting from 32kbps to a variable which at that time was up to 220 kbps I think. And the sound depended a lot of the speakers. In the PC starting from 128 kbps sounded good, but in the hifi equipment to a properly bass sound must had be the variable, not less. Even if actual 320 kbps mp3 is said to be enough, I consider quality cd, be WAV, be FLAC, etc, the most honest format to sell music, just in case, the original, nothing removed.

Years ago, I was tracking thru 18bit motorola converters. I was dropping the teac four Trac drum tracks down to digital. I noticed it sounded much more like the tape in 24bit than sixteen bit my sampling rate was 44.1 in both cases. I learned 24bit is better for resolution. However I had to mix down to 16 bit digital in this case. My hardware could only handle 16 in the multitrack window.

[@frostmediaprod344]

I think there is a better low bitrate formats than the mp3 like m4a aac, ogg, because the spectral analysis sometimes shows that some mp3 converters screw up the songs by cutting too much frequencies. So you still get 320kbps but in reality it's less.

[@krisjonzmusik]

I do a lot of sound design and multiple renders of audio. Stretching, bouncing etc and have recorded at 96k for the last 12 years for that reason. Also my clients want 48k almost 100% of the time so the conversion is seamless this way. I think some of the “myths” of higher SR are leftovers from when converters weren’t as good (maybe), like early aughts. But if you really wanna hear a marked improvement, get a master clock. That was an eye-opener. I run 96/24 with Lynx Auroras and a Big Ben-that’s enough! But this video gets into consumer habits, and listening-and I agree. CD is fine and I really prefer vinyl. But it’s apples and oranges comparing processing digital audio with delivery specs vs listening to music. My .02.

[@SonicScoop]

Absolutely, for sound design or sample libraries where you’ll be time stretching audio or pitch shifting down significantly, higher sample rates make sense. That’s one of the special cases mentioned near the end of the video. And if you’re working primarily with video, 48k there is the norm, so may as well deliver it that way instead of sample rate converting a 44.1 file. Thanks for the comment, -Justin

I listen to MP3s on an almost 20 year old Zune with Beyerdynamic studio monitor headphones and the sound quality is flat out amazing. 44.100/16bit is more than enough to capture and reproduce sound that humans can hear and a good ripped Mp3 sounds nearly identical.

[@mk0x55]

Most of the difference to music quality appears to be down to the recording and mastering process, in my personal experience. While 320 kbps MP3 might be hard to distinguish from 16/44.1 FLAC... I wonder whether that's not really dependent on the hardware to a good degree. The better setup, the easier the perception of transients and hence space, distance etc., might be. I can for sure tell that the quality difference between streamin of something lossy like through Spotify versus lossless like through Tidal, is night and day, in clear favor of the latter. That is though probably also mostly due to Tidal sourcing the tracks much better. I've been custom-upsampling (like 64M taps sinc filter using SoX) my FLACs to 24/96 (for my phone) and 24/768 (for my home setup) because it gives me a bit more refined, clearer and smoother highs, which I actually hear the difference in (although the differences are kind of subtle, they won't really hit one in the face), and that's comparing FLACs, and even that on mid-fi equipment, nothing that breaks the bank. MP3 is really out of the picture there. Sorry for not having done the double blind test experiments! Will for sure try that though.

[@mk0x55]

Also, today's delta-sigma DACs and even some other DAC tech like R2R tend to oversample themselves, unless you supply them a high-enough input stream. Save for Rob Watt's M-Scaler or something in that league, the small chips of these DACs that need to do their resampling in real time can't really compete with an offline process that takes a few minutes per track on a modern CPU core and a good 6 GB of RAM to finish... And another very clear benefit of oversampling to mention is that today's music that gets released is most often overly loud and already digitally clipped, which means informations is already lost in there, mostly impacting the higher frequencies. A proper upsampling process (after digitally lowering the volume beforehand, sometimes by as much as a whole third), can reconstruct the waveform and partially undo the damaging effects of digital clipping. Perhaps it is this that justifies the oversampling hassle to me, since the space storage and the bandwidth between my home NAS and my living room computer doing the audio playback, is not really an issue.

[@Allan-et5ig]

Justin, loved it. Three questions: . A famed producer (I believe it was Aerosmith's producer said that excessively high resolution audio was allowing us to hear details in the original recording that weren't there and therefore were a bad thing. True/false? . Jimmy Page said the Zeppelin catalog was recording at such fidelity it's future-proofed for years (or more to come). Page specifically said for future "higher audio standards," which as they're in the future don't yet exist. True/false? . I thought the sound on VHS was/is pretty groovy. Isn't VHS tape a NON digital format? Hence, the sound is 16 bit which as you noted no one can really distinguish from 24 bit. Hence, analog can reproduce in the instance of VHS sound as close to the source as digital? Not a trick question. P.S. I think one big misconception you blew-up in this video, is that if you record say, a giraffe making a sound at a zoo - whatever sound they make at 16 bits and you record it at 32 bits - most folks, including many professionals, believe that at 32 bits of 'resolution' you'll hear greater fidelity with 32 bits. You'll hear a better sounding giraffe, as well as the sound of garbage rustling on the ground. A better wind sound. Maybe human speech, better, from visitors to the giraffe enclosure.

[@SonicScoop]

Yes, I think those first two examples come from a misconception about how this stuff works. There are a lot of people who are great musicians, producers-and in some cases, audio people-who don’t really understand the situation fully. They usually have never done double blind trials on any of this, and often don’t exactly understand what’s going on under the hood. But that’s ok. They can be tremendously great at what they do and be mistaken about this. I was once. Jimmy Page is an amazing guitar player. That doesn’t mean he knows how digital audio files work, or that he’s done blind listening tests at various sample rates or bit depths. That’s not really a criticism. You don’t need to know any of that to be a great musician, or even a great producer or mixer. If you had to pick between being amazing at guitar or production and knowing how digital audio works, the first too are way more badass :-) VHS CAN be digital (see ADAT) but is usually analog yes. (Technically you could record digital signals on a reel to reel take machine, and some companies made such machines early in.) But yeah, generally analog in both cases without getting too nerdy about it :-) Analog formats actually have lower dynamic range and higher noise floor than 16 bit. Good vinyl would be the equivalent of about 11 bit in that regard if I remember correctly. I’d imagine VJS would be around there or lower in effect, but I don’t know right offhand. Generally speaking, any analog formats are going to sound less like the source than a 16/44.1 file. The only thing that comes close is an absolutely excellent tape machine running at 30ips. That might come close to sounding as close to the source as any reasonably well built 16/44.1 system, and would be orders of magnitude more expensive. But analog can sometimes sound damn COOL, even if it doesn’t sound exactly like the source. A less than stellar tape machine running at 15ips could sound more badass than the original source. That’s subjective. But it probably won’t sound as close to it as even a basic stock AD converter built into a laptop. That’s objective. Hope that helps, -Justin

[@cornerliston]

One benefit of using 96 instead of 48 at recording is the AD converters allow me better headroom. Not sure how to explain this in technical terms other than what I see when I clip the sound at 48 compared to 96. Another benefit of higher sample rates is signal latency. Although I've never considered 96 being “super high resolution.”

[@SonicScoop]

Headroom and dynamic range is a function of a bit depth, and of the analog components of your converter. Sample rate just doesn’t play into it, in theory or practice. If your converter works differently at the two sample rates for some reason, that could be possible I guess. I’d like to know why. That seems like an odd design. But that seems unlikely. If anything, it could be slightly less easy to clip a lower sampling rate because you are dealing with less signal overall because the reduced supersonics and lower anti-aliasing filter. Have you done any properly controlled tests of this where you can absolutely confirm this is the case? Please share if you can! I’d be curious to know more. As I’m sure you sneaky know, we all think we hear things that we aren’t really hearing. It’s happened to all of us. I’m sure you’ve had the common experience of fiddling around with an EQ knob, thinking you were changing the sound subtly, until you realized it wasn’t engaged, or you weren’t on the right channel. That’s just part of being human. As powerful as we can develop our listening skills, it is true that our minds will always be more powerful still. If you have a test you can share that confirms this, I’d be very interested to see it. Thanks much! Hope that helps, Justin

​@@SonicScoop Many thanks Justin! I noticed it when running outboard reverbs both at 48 and 96. At 96 I had more headroom before the signal clipped in the converter, RME ADI-8 DS Mk3 via ADAT to/from Apollo 8. So it was purely by eyes I noticed about signal not clipping at a certain level. Nothing else was engaged or changed so I was a bit surprised myself. Probably more to it than headroom being changed then : ) I'm like you-being aware of the sound while fiddling and thinking yup that's a tad better-and realising the plugin wasn't active : ) I have that perspective when listening to anything these days but trying to explain how the brain fools us is a difficult task but I'd be happy if you talked more about that, blindtesting, do we actually hear the difference we think we hear etc etc.

Thank you I just discovered your channel, this was a great video!!

[@ryangrow1]

Try as I might I have yet to be able to hear the difference between cd quality and the high res audio, which could explain why sa-cds never took off. I’ll have to try the MP3 320k to see, but I know that at 256k I can tell but it’s really difficult.

[@MichaelCosta_]

Well done on this video! I have been singing this same song for years on forums and with students. As a delivery medium, why do you need more than 100dB of dynamic range? (dithered 16 bit). The part I think many still struggle with, and I can see it in some of the comments here, is not understanding the bit depth of a session. (Speaking about Pro Tools here, but I believe other DAWs are similar). If set my session to 16 bit and fill it with 16 bit files, we are not operating in a 16 bit world. Every DAW these days has at least , a 32 bit floating mix engine. You are mixing and outputting a 32 bit signal IN SPITE OF THE FACT THAT IT MIGHT BE MADE UP OF 16 OR 24 BITS FILES. The bit depth of the session only relates to the bit depth of any files you record into the session or any files you import that require conversion.

[@pigknickers2975]

I started as an engineer in the 80s. 60db headroom was about what we had. When the 16 bits came in no one could believe how low the noise floor was. All DAWs now have 32 bit internal buses and some even have 64 bit summing. No one seems to understand. I still deliver projects at 24 bits as otherwise, people don't think they are getting their money's worth. This is to make vinyl from lol

[@Take-the-Ticket]

Here is a blind test that will change your mind, Justin. Listen to a 320k vs. a wav or flac (create both from the best same source) of The War on Drugs' "Lost in the Dream." I have, and for a fact, I can tell you there is a specific character that shows the difference. I challenge you to notice it, it can be deciphered in the first minute of the song. Another stunning mix was Morning Phase, equally decipherable. The sense of detail and SPACE that is destroyed by 320k is obvious to me, at least. Most won't notice, so don't stress, that is true. But when you personally want the best, why not go ahead and mix for that. Try to hear it, try to make it.

[@SonicScoop]

Interesting to hear! What are you using to listen to the these properly double blind? I can tell you that I have had similar experiences in sighted listening tests. For instance, when I created a similar listening test for our readers, I could have sworn up-and-down that I could hear the difference when listening sighted, and that so many people were going to get it right. But as soon as I properly jumbled them up so I didn’t know which was which, those differences seemed to evaporate like a mirage. Ultimately, the results of thousands of responses to our online test were no better than chance: www.trustmeimascientist.com/2012/04/02/take-our-audio-poll-do-we-need-higher-definition-sound/ If you can consistently distinguish this, that would be amazing! No one in the world as of yet has been able to show that they can consistently distinguish between 320kbps and any higher resolution format in a proper double blind listening test. I’m not saying that it can’t be done. Just that it never has been yet on record. If you can do it, that would be amazing. I’d happily write a glowing full length article about you and how you are able to do this so we can share it with the world. I’ve had this challenge out for almost a decade now, and so far no one has done it yet. It would be awesome to finally put a bow on it. What software or hardware solution are you using to do proper double blind listening tests on your end? Is it an ABX tester? That could do the trick. Thanks, Justin PS: Here’s the original challenge on my old blog. It’s been seen tens or hundreds of thousands of times, shared all around forums and all that, but no luck yet!

I did find in another of the articles the foobar can have an ABX tester plugin, I'll do that. My previous tests had my wife switching the tracks; a program that does that will be fun, so thanks very much for that. Also, please know I meant no disrespect, I love your channel and learn what I can from it :)

[@scoremix8556]

320k MP3 isnt a "hi res" format - its still a compressed (althogh half decent) file. Im pretty sure Justin is referring to higher sample rates and bit depths.

[@palethorn]

I was running this video in background, and that 15kHz startled me, I thought something was wrong with my head. Anyways, it was mathematically proven that you only need double sample rate of what your maximum recorded frequency is, and that would give you accurate reproduction. Any errors in audio are not likely and negligible. Search for Nyquist theorem. 44.1 sample rate can be used to reproduce frequencies up to 22.05kHz. Only a few people, if any at all, can perhaps hear that. Noise for dogs.

[@axymoulm]

I use to bounce my music from Cubase (6) to a 44.1kHz/16Bit wave file, then drag it onto my iPod mini, go out to smoke a cigarette and gaze into the distance. It occured more than once to me, that I was bouncing out an 320kBps MP3 and was not aware of it. The funny thing is: That iPod makes it a blind test without my provision - it doesn't show or tell you in any way which format is being played back. BUT: My nearly 40 years old ears seem to reveal it - whenever I listen to one of my productions and I have the feeling it's not uncompressed sound... guess what: In fact it would be compressed, really. I would yet have to fail on that one to conclude an MP3 sounds just as good as a PCM. But don't get me wrong: I agree wholehartedly to what you say in this video.

[@bc8Sooners]

Thank you. Your video helped me staying with Spotify for the UI, multi-platforms (Connect) and international songs selections. Honestly tried Apple Music and Tidal and just not getting any additional benefits.

[@SonicScoop]

Yeah, 320kbps is a pretty amazing consumer format. Improvements from there have routinely been shown to be existent in double blind listening tests, so whichever service you prefer for other reasons is probably the more important variable. Glad you found a choice that makes you happy! Very best, Justin

[@Bonzvy]

Last week I switched to high sample rate for my mixing template. Not for that "super high quality" sound (actually when the files were recorded at 48kHz than they CAN NOT be converted to higher samples rates with all that extra information) but for the digital processing I use. Some of them have oversampling but some simply don't. And those plugs which don't have oversampling CAN achieve a more accurate harmonic saturation/distortion. It depends on how well the plug-in was coded. So the sampling rate of my project is high but my exported file is still 16Bit 44.1kHz/48kHz. The only downside is the processing power - but hey with this "trick" you convince yourself using less plug-ins 😉

[@SonicScoop]

If it works for you keep on doing it! I would suggest that you eventually do an experiment though, just for fun and certainty. Try this: Bounce your mix from your 48k session. Then, copy your entire session from 48K to 44.1 K. Then, bounce that otherwise identical mix as well, to the same bit depth and sample rate. Now, load both up into an ABX tester and see if you can hear the difference! This would be one way to confirm that you were actually getting the benefit you hope you are getting. Maybe you are, maybe you aren’t. I don’t know! I have recommended this to a friend who worked at 88.2, and they have found that they couldn’t tell the two files a part. In some cases they stop using 88.2, in some cases they didn’t. But in no cases so far did they hear anything like the kind of difference that they thought they would. Maybe your situation will be different. In either case, if you try it, please share the results here! A lot of people would be interested to hear them I think. Thanks and I hope that helps! -Justin

[@u_ok]

Thank you, Justin , this podcast has changed my view on everything))

[@latheofheaven1017]

The other thing is that although we do have the best audio formats available to consumers now, they don't listen to music in any way to take advantage of them. Phone speakers? Laptop speakers? Alexa speakers? People aren't really even listening in stereo.

[@SonicScoop]

It’s true, people can listen on some pretty garbage speakers these days! But on the other hand, if they wanted to, really great sounding speakers and headphones are available at a much better fidelity and a much lower price than ever before in history. That’s kind of awesome. Let’s not romanticize the past too much either though. Back in the day, most consumers also listened on total garbage speakers and hardware, often as bad or worse than the laptop speakers of today :-) But people have very fond memories of listening to music on their terrible tiny old transistor radios, or even today on their phones and laptops or even a single shared earbud with friends. As cool as good audio is and can be, music is ultimately way cooler and way more powerful. Hope that makes sense, Justin

[@latheofheaven1017]

@@SonicScoop Hey Justin. You're right of course. Transistor radios were shrill and distorted. I inherited a basic little reel-to-reel machine when I was about ten, which only had one speaker (even though it was a stereo tape head). But then we also had a radiogram! The turntable in it ran at 33rpm (or less), not 33/3rd. I only realised when I took my albums over to a friend's house, and at first thought their machine was running fast. But everyone else's was the same, so it was our radiogram that was wrong.

[@TheJonHolstein]

I would somewhat argue against that, I would say that a lot more people have headphones that sound good, compared to how many people had good sounding headphones or stereo systems in the past. So while some listening, does take place on sub par playback equipment, a lot of people actually also listens to equipment that is far superior to the typical listening equipment just a decade or more ago. However, that is an issue, that mixing and mastering focuses so much on speakers rather than headphones, as most listening with quality equipment these days is actually with headphones, compared to the past when stereo speakers were the dominant listening environment of quality. This causes a lot of issues with the stereo representation, where speakers provide a channel crosstalk that doesn't exist in headphones, and the fact that we can't tell the direction of low frequency sounds in a room, but if if is only sent to one headphone we can.

[@keng8883]

[@kylegushue]

Higher sample rates introduce less latency when monitoring natively via the DAW. Once tracked at high sample rate for low latency, there is no need to introduce sample rate conversion, which will cause degradation.

[@markhopkins5352]

I downloaded audio from a song posted to KZbin and then listened to the CD version of it a few months later. I was shocked how some of the percussion sounded very clicky on the CD and warmer on the mp3! I’m not sure what YT does to the audio when uploaded but it definitely didn’t make it sound bad ☺️

[@SonicScoop]

KZbin probably removes more high frequencies than is needed, especially with its standard resolution videos, which often have bitrates as low as 128kbps for sound. Unfortunately, they don't offer any 320kbps audio that would be indistinguishable from any higher resolution. Their 256kbps versions, which can only be found on their HD videos, is not bad at all, but the codec is not as good as those from other audio focused sites from what I have found. Unfortunately, I doubt that you downloaded even the 256kbps file from whatever sketchy side served up the download, so you could be missing a lot more high frequency in the YT download than is ideal. Go check the file and let us know what bitrate you got. I'm guessing maybe 128kbps? Hope that helps make sense of it! -Justin

[@Truth565]

Great video and description of the whole high sample rate argument and how it reflects to the quality of the sound. It also explains why my interface sounds better at 48khz and up. There is an endless thread on GearSpace on the whole subject.

Thank you very much. Now I can stop searching for "better sound" that I cannot hear and stick with my humble music streamer and Cambridge Audio.

[@wangodan]

Thank you Justin, this comforts me in my unashamed attitude of "If it sounds good, it's good"! I have a question about the "Air Band" on Maag plugins, I really like the "brightness-not-harshness" it allows my 58 years old ears to perceive and appreciate on instruments and mixes. I usually use 4-7dB @ 20k and only recently used 15k on the EQ2, should we be cautious of unheard frequencies causing aliasing generated by the plugin at 20 or 40k?

[@SonicScoop]

Good to hear! Aliasing should’t be a problem and should be filtered out if everything is working properly. But there’s a chance that to you get ears you might be boosting more HF than you realize :-) It could be good to double check things on a frequency analyzer to make sure the super high end you have trouble hearing doesn’t look to crazy relative to references. Either that or visit a high school classroom, draw your nails across the chalkboard to get their attention, and then ask them for feedback on your mix ;-) Hope that helps! -Justin

[@JimijaymesProductions]

My argument for using 24 or 32 bit float is just headroom, I can record really quiet sources and then gain them up and compress the living shit out of them and the noise doesn't come into that audible range. For consumer side I go 48/24 because it is standard for video.

[@rbrown2925]

I'm going to be getting theoretical here but what the heck; I get aggravated, too. Much of this presentation is based on a common misunderstanding of Nyquist's sampling theorem regarding the reconstruction of a signal that has been sampled at anything strictly more than twice the highest frequency present (the "Nyquist rate"), and a common misunderstanding of the frequency content of audio as based on Fourier analysis. Nyquist reconstruction only works if the signal has a limited frequency spectrum but, according to Fourier, any signal that is of finite duration has an infinitely wide frequency spectrum, thus Nyquist reconstruction does not apply to music. Even a pure sinusoid of limited duration has an infinite frequency spectrum (I suspect many audio folks don't realize this); only a sinsuid that started at -infinity and runs to +infinity has a frequency spectrum that looks like a spike. Just imagine any three evenly spaced samples of a single cycle of a sinusoid, around the Nyquist rate. According to the video, you can reconstruct it but there's not a chance. Further, Nyquist's reconstruction requires the availability of every sample to reconstruct any point of the original waveform. So, even if the sampling rate wasn't an issue for a signal that somehow had a limited frequency spectrum, you couldn't reconstruct anything in real time from a digital input stream. You'd have to wait for the entire song to download before you could even start playback. Our digital audio realities are fine but I get aggravated when I hear theories that don't apply being crushed to explain how things work. And while I agree that our hearing just isn't good enough to benefit from high resolution audio, I think a distinction has to be made between (1) what difference high resolution processing makes when it's used throughout the entire recording chain, and (2) what difference high resolution audio makes just for the final output. I suspect high res makes a significant difference in the first case especially if a lot of processing is used, if for no other reason than cumulative errors (resulting in unwanted artifacts) are minimized, but the evidence is in regarding the second. We just cant hear the difference.

[@ajkxng]

Exactly what i been looking for

[@VictorGonzalez-jh7kz]

Well illustrated, on top of all that we should consider the frecuency response of microphones (good old SM57 does not go over 15 kHz), preamps, etc. Just saying,

[@TiqueO6]

I think we should all consider that when listening to pure tones as hearing tests it doesn’t reflect the real world where tones are combined. It’s the simultaneous interaction between frequencies, even the frequencies that are considered outside of the range of human hearing because of single frequency hearing tests primarily, that can get very interesting so to speak in this conversation.

[@michaelanderwald4179]

That's not how it works. Yes, there's intermodulation distortion - at least in theory - but that's too low in level to be audible over the actual playback material, and probably not present at all in actual recordings. I'm not a fan of test tones, either. But this often cited euphonic interaction between frequencies is a myth. There are interactions, but they're either not audible, or just as audible at normal sample rates.

[@FloatingOnAZephyr]

@@michaelanderwald4179 It also sounds more like something that would result in amplitude peaks rather than frequency distortions. If we can't hear a certain frequency, it's not going to matter much if two sounds at that frequency interact a little and boost in volume, as we can't hear it. Perhaps I'm mistaken.

[@michaelanderwald4179]

@@FloatingOnAZephyr Depends on the type of interaction of the frequencies with each other. Intermodulation distortion can go much lower than the frequencies that cause it, but it's low in level and probably not something that would sound good. It can actually sound a bit like aliasing, so very much not harmonic at all. I've sometimes wondered if some people prefer DSD recordings because the energy around 100kHz due to noise shaping adds some kind of biasing effect on the playback system. But that could be added in other ways to a "low" resolution playback system. Also it's pure speculation.

[@nagynorbie]

Great, informative video !

[@51bpm]

You're sorta right and sorta wrong. When testing my fave synth at 2441 and 2496, I was shocked at the difference in clarity. Always good to start at the highest possible quality and then Downsville, if needed ... that's my 2 1/2 cents.

[@SonicScoop]

I think I mention in the video that synthesis is one of the reasons you might reasonably use a higher sampling rate :-)

[@soundknight]

I have 100s of classical cds at 16 41k. The biggest difference I can hear is not in the quality of the amplifier, the DA converter, the headphones, the full tube amp, the toroidal transformer... It's in the microphones, mic placement, instruments, studio preamps and mastering. I do think a small difference is gained however in SACD.

[@kjererrrt2381]

i don't seem to hear anything above 16khz. when i was a boy having equipment that had frequency range up to 12khz was quite good. and everything sounded just fine - percussion etc. for example a sharp boombox. or a turntable with a built in amplifier. they sounded just fine.

flac is lossless. A great mathematical data compression trick. I remember it translating even highest samplerates lossless in audio information. The rest I enjoyed a lot.

[@kylegushue]

End consumers getting the file in the same format it was recorded/mixed avoids a Sample Rate Conversion, which can mean less degradation. Higher sample rates give a more accurate trace of the analog/electrical wave form.

[@SonicScoop]

If you want to avoid sample rate conversion, don’t use the unnecessarily high sample rate to begin with :-) As far higher sample rates “giving a more accurate trace of the waveform”, I’m sorry but this is incorrect. That’s the exact misconception that we start off the video with, on purpose. There is just no mechanism in physics by which increasing the sample rate can do anything except for increase the highest frequency you can reproduce. It’s a bit of an all or nothing affair: Either a given frequency can be reproduced perfectly at a given sampling rate, minus some noise (which is determined by the bit depth) or it can’t be. This can be confirmed for yourself with proper testing. Similarly, there is no mechanism by which increasing bit depth can do anything but lower the noise floor. If you believe that there is, that would be an amazing breakthrough discovery and science! I mean, could you explain the mechanism by which anything else could occur? I hope that helps, Justin

[@kylegushue]

@@SonicScoop when you have more samples per second, there is less rounding going on as the digital waveform tries to approximate the analog voltage (input). A hypothetical infinitely sample rate would track the voltage perfectly, to the atomic level or beyond. There would be no rounding, at that point. Its calculus. Approximation of a circle using discrete values. More "steps" equals a closer approximation to the continuous curve. Why not use less noise, noise is not typically desired. Even if not audible, it has interaction with the audio. There is no universal reason to not be technically better. If for no other reason, than archival purposes. If you null test an mp3 @ 320kbs, and a 24/96 file, there is no residual sound? Interesting discussion. -Kyle

[@kylegushue]

@ReaktorLeak im talking about the capture at the ADC stage. Voltage to binary. A "perfect" conversion would track the voltage fluctuations down to the electron. Otherwise your missing information at conversion. ie the information that would otherwise be in between samples, is not recorded, it is ignored, the waveform jumps to the next discrete value, the analog signal is continuously variable. Up to the limits imposed by the hardware. Trace the outline of a circle with straight lines, once with 1" lines, another with 1/4" lines. The shorter more frequent lines give a "truer" representation of the circle. This is akin to sample rate. More samples, more accurately traces the voltage functions aka the analog audio waveform.

[@kylegushue]

@ReaktorLeak you cannot recreate the circle however, because samples are discrete values (straight lines) in your example you would have a triangle. The samples cannot reflect the "inbetweens". The voltage change happening in between samples. "Reconstruction" of the inbetweens ends up in averaging. You don't "know" the voltage fluctuations, your guessing them based on the two points. A momentary transient occuring between two samples, would be ignored. It would go undetected, and get rounded/averaged away. The samples can't dectect things in between samples. They are akin to steps, not curves. Calculus shows us that more discrete values (samples) more accurately trace a curve than less. Its just like frame rate in video. 29fps is fast enough to fool the eye, until you slow it down. Higher frame rate is always truer to continuously varible.

[@kylegushue]

@ReaktorLeak you can perfectly re-create the circle IF know ahead of time its a circle. If you do not know its a circle it could be any possible configuration of lines between those 3 points. A converter doesn't "know" the voltage fluctuations in between samples.

[@MrmelodyUs]

Its NOT just about what frequency you can hear up to. If you can't hear it your equipment might not be up to snuff, or youtube, or BG noise is masking the sound. This discussion totally ignores the psycho-acoustic dimension as well as harmonic granularity.

[@SonicScoop]

I find the only benefit of hi-res releases are that the albums normally receive a better mix, Metallica's Death Magnetic is a great example... the retail CD is a brick walled mess victim of the loudness war and due to the compression it's actually tiring to listen to it, the 24bit/88.2khz hi-res release just sounds better due to the mix and lack of compression, so I just converted the flac files to 16bit/44.1khz and burnt myself a CD that sounds better than the one I parted with cash for..

100% this. Of course it’s not a benefit of the hi res format, but having a better mix is a huge reason I buy hi res.

Yes, that is a valid reason to repurchase etc. It's a shame however that people are being convinced they should buy because of the numbers and not because of the fact you get a better mastering or better recording. If you convince everyone it's the numbers that matter, they will rebut every CD ever owned by them and it also attacks the second hand market. Imagine reprinting a book and encouraging everyone to rebuy because the new print has a HD font that will improve your immersion in the text.

[@fjzingo]

Done quite a few tests and there are subtle differences in the amount of air or silence you hear in great audiorecordings in CD quality compared to compressed mp3s or AUCs leading to better separation of instruments. This is more apparent the more the file is compressed where reverb or room tails disappear. Lossless compressed sounds like CD quality even through good DACS(use a RME babyface). I cant hear any difference in quality beyond CD quality. The differences people hear is most likely technically related…some ADDAs just record and play back more reliably than others. So in all I completely agree, going beyond CD sound quality is just a waste!👍

[@fjzingo]

@nicksterj MP3s didnt exist when the debate about digital vs analouge sound started. First time I heard it was with the arrival of the CD format. The whole record industry went bananas trying to quickly digitize their music catalouge to cd with varied success. As you say, a well mixed album and mastered(this is something you really did to fit the dynamic limitation of an LP). Unfortunately almost all popuplar music today is compressed, autotuned, grid quantized and overmixed to death in the loudness war….

[@fjzingo]

@nicksterj saw the resurgance of vinyl already in the 90s, but now its bigger than in a long tume. Same thing happenings ng with film cameras for example…..guess its just how thingswork. Off course the motivation will be something like sounds better, better colours, better control over gear. Dont know if you followed the development of syntesizers, it has just come around to be back at the 70s…..people search for differnt stuff and are nostalgic at the same time.

[@fjzingo]

@nicksterj I didn’t say that the sales of LPs were high in the 90s, there were plenty of used record stores. Many artists started to release LPs again way back early 2000s and there have been a small audience buying these as collectables. And you are right, now it has exploded, its common to be 20-30 something owning a record player….most wont argue around sound quality…..they just keep it next to their vintage camera and dumbphone.🤣

[@fjzingo]

@nicksterj there were quite a few stores popping up close to Carnaby street London very early, were completely surprised that people even cared at the time, it might be that memory plays me and this was early 2000s...seems sales really took off again mid-late 2000s in many countries with a peak in the 2020s in according to wiki. On the jazz scene it's pretty common that the artists bring their Vinyls these days. Not so strange when there is simply no revenue at all from streaming services....

[@TigroGumi]

This theory is true with speakers mind. I tweeter able to go to 30k or 40k plays the 20k better because 20k is now not right at the physical throttle of 20k because it will begin to drop off at the point before stopping. Although that theory only counts if that is the purpose of the tweeter hitting above 20k. Physically it does give it space. It's why 3 ways and above do a better job... But that is there being more speakers handling less spectrums at the sametime. This a phycical thing so the diffrence does lay in this... the audio is best to not go above 20k even though they can handle more. There can be a diffrence in headroom with audio coming back in from highend analog equipment but not going out into it. With that said the diffrence is so little that the complication of downsampling that afterwards is kind of pointless. Consumer products are focused on going out which is pointless sending out anything over 20k. There is a diffrence with some plugins mixing down to two channels but then again the diffrence here is the sound you are looking for. There's a gain in the sound of analog emulation plugins (some of them, not all of them), but going out to analog in a high bit rate doesn't make sense. So I would bounce each track that is better in a higher bit rate then turn down the bit rate to 48 to go back out to analog. That is a bit of a headace though for such a tiny diffrence but that would be good for anyone with no real analog equipment. But when it comes to the resolution at the end... then 44.1 and 48 is more than enough. I stick with 48 due to the flexibility with video This was a video with bits I hadn't thought about before that really relly helped me re remeber things and add a little extra in those thoughts

I swear that CD's sound slightly fuller in the low end to me in my car vs. me playing the same album on Spotify on my phone using an AUX cord. I have no idea how much of this is just placebo or if there's something else at play, such as the DAC in my phone or whatever.

[@mishm299]

Spotify is objectively worse imo, I listened to my CD version of an album then the Spotify stream and the spotify one is so muddy compared to the CD, like there was a blanket over it. I'm pretty sure I have "high quality" enabled on my Spotify too, and was listening to a downloaded album so it should've been optimal quality

[@fernandoferreromusic]

That is because of the Aux cord , you will get some armonic distorsion from the plugs themselves and also if you are using a 3.5mm jack the lower freq range is not as acurate ,, /( correct me if I am wrong but from 120Hz down / so yes, you are rigth, you can feel and hear the diference , but it is not because of the file audio qualitty ;)

[@mishm299]

@@fernandoferreromusic I thought it might be the aux cord, but then I listened to the same album on my MP3 Walkman (same cord) and it sounded much closer to the CD quality than the Spotify version :o I think this might be specific to Spotify, they must do something to the audio files even if they're technically at 256/320kbps I think they do some extra compressing to save space.. although it could also just be my phone's aux jack vs my Walkman jack, the phone jack being inferior?

[@SonicScoop]

There are a few factors here. One is that you could be listening to lower resolution mp3s, such as 160kbps instead of 320kbps, depending on what version of Spotify you’re on. Trained listeners may be able to discern subtle differences in that case. (Though most people can’t.) Another is the the DAC, sure, but often more importantly, the analog components of both your phone and your car stereo that aren’t in the equation when playing the CD. Another even bigger factor could be volume differences between the two inputs, including Spotify turning down louder material, but also the audio input (or phone output) being quieter than the CD. Level differences explain a LOT in audio preferences. And Spotify does indeed turn down the loudest material for consistency, which your CD player and your MP3 player likely doesn’t do. Even if none of that was at play, and you had identical levels and audio (which you probably don’t) sighted listening makes a difference as well. I could go on. But I probably shouldn’t! :-) I hope that helps, Justin

[@charlesberton2581]

I use Wave 48K at 32 float because I believe if I yell too close to the mic, and it goes way into the red by accident, it won't distort. When I export to MP3, it still sounds good. Am I wrong?

[@KKMcK1]

So, 24/48 as a standard. 32/96 for post-production RX, if necessary (the elimination of digital distortion). Eh???? I suppose the only thing that comes to mind is the air at the top for 3D resonance (psycho-acoustics?). Having a 32/96 interface, causes me to ask, why not? I get the file size argument, but being that the end product is going to be crushed by the streaming services, why not produce at the higher rates as an offset to the crushing that is going to occur on Spotify, etc. I am fine with 24/48. Really, the only real argument remains the file size within the production computer. Thanks for the emotional battle I now have to have with myself. Yeah. And you did just blow that lunch date with Neil Young. Thanks for always giving me so much to think about!!!

[@ManuelGuinand]

Really, I mean REALLY great episode!

[@HungryForTastyFoodAndComicArt]

Hold on... if I'm understanding this correctly: I can record a VO using a sample rate of 44.1 kHz, and I can do the same reading in another recording at 48 kHz, and the only real difference is that some of the higher frequencies (which annoy me anyway) won't be there in the 44.1 kHz?? Or have I misunderstood?

[@kelainefes]

Human voice doesn't have much information beyond 18Khz, I mean there is something beyond that in noisy consonants like K, T, S sounds, and in the sound of breathing and other things like mouth clicks. But honestly the part of those sounds that you will loose going form 48KHz to 44.1KHz is not something that you would want to hear, if your ears can actually hear it and your sound system can reproduce it.

[@HungryForTastyFoodAndComicArt]

@@kelainefes Thank you very much! I mean with VO, most of what you mentioned is something that narrators etc. work hard to eliminate anyway, or rely on audio engineers to remove for us! Again, thanks! 😀

[@kelainefes]

@@HungryForTastyFoodAndComicArt Yes, for a voiceover an engineer would want to remove mouth clicks and greatly reduce the amplitude of breaths to the point you fell them more than hearing them, and the consonants would surely not be receiving boosts in very high end, and depending on the microphone used would be processed to sound a bit "darker" or "smoother" and certainly not brighter.

[@HungryForTastyFoodAndComicArt]

@@kelainefes Exactly, again, thank you 😊. (edit) - many of us have found a huge difference between a Røde NT1A, an AKG C214 and a Lewitt Subzero.

[@SonicScoop]

Pretty much! There is some chance that a given converter could sound slightly better at 48k than at 44.1k if it is using an analog anti-aliasing filter, so you might get a teeny bit flatter response around 20k or so with the 48k mode in that converter (if you can even hear that high) but that’s about the strongest reasonable case you can make, I think. -Justin

[@BLACKSYNTH]

Great video, however I’m super disappointed you never mentioned anything about system latency at higher sample rate.. it’s dramatically reduced as you go higher which is so much better for recording esp say on my fully weighted piano controller. That makes sense for me to run at 96k and the main reason I do. I have a 16 core and 32gb and a 2TB SSD so works well. I read a lot about plugins based on analog gear and saturation works/sounds better at high sample rate. It was super scientific and a bit over my head something about harmonic distortion stuff or cross over, I’m not sure But seems to sound better to me On things that are distorted for what ever reason.

[@SonicScoop]

That’s a fair point, though it’s a bit of a double edged sword. It’s true that at the same buffer size you’ll get less latency with a higher sample rate, which is good. But the higher sample rate, file size and CPU load means you’re more likely to need a higher buffer size! So in practice, on the same relatively dense production it could work out to be about the same either way. For instance, at 48k, maybe you could use a buffer size of 64 and have no meaningful latency to really hold you back, while at 96k, you’d be able to get away with a 128 buffer size and have the same latency.... but you’re also likely to need that higher buffer size due to the increased CPU load! There are hypothetical cases you could make to tilt the scales in either direction, so it really comes down to your specific use case and what works for you. Wish I had mentioned it! Though the episode was already getting a little long. Thanks for the comment. Hope that helps! -Justin

[@BLACKSYNTH]

@@SonicScoop It does shed more light on it! Thanks for explaining more about buffer size and taking that into account. 👍

[@patrickjonsson-good2588]

this is AWESOME! next time I'd love to hear some peak compression on your voice to make things just a bit more audible :) also, my cat looked at me funny when I unmuted the video at around 8:45 😹

[@SonicScoop]

Usually there is a whole chain of compression, limiting and EQ on the voice, but there was a glitch with Premiere' s export where none of it actually got printed. By the time it was uploaded, getting thousands of views and discovered, it was too late to change it 🤷 KZbin doesn't allow you tor replace audio or video unfortunately. Ironically, the only complaints about this video's audio quality is that we didn't degrade it ENOUGH by making the audio less pure with tons of compression, EQ and limiting. Kind of shows what really matters in audio. In a literal sense, this uncompressed and untreated audio is more "real" and "high fidelity" than a voice that has gone through normal amounts of audio treatment for this kind of format. -Justin

[@richy2496]

The only time I really heard a difference was listening to an acoustic album recorded and mixed in DSD system. It had much less of that high mid synthetic quality of conventional PCM converters. However is not practical because even DSD has its limitations.

[@SonicScoop]

Interesting to hear. Did you listen to a blind comparison in any way? Like, was the whole mix also done in PCM and you had both exports to listen to together side by side without knowing which was which? I have no doubt it sounded amazing, but it's hard to attribute that to the format without a properly controlled listening trial. Without that kind of listening, it could easily be that it sounded awesome for a variety of other reasons, right? Hope that makes sense, Justin

[@sub-jec-tiv]

I still would deeply recommend using AAC compression instead of mp3, because most people are getting poor quality mp3s that were converted poorly. Or worse, they’re getting served a low bit rate mp3. Absolutely you can hear mp3 artifacts with 1. bad conversion; or 2. Lower-bitrate. Seriously the sound i get back from Soundcloud is noticeably inferior to my master in the highs. I wish Soundcloud would start using AAC because it is a wonderful sounding codec and could totally work on their platform. AAC is an Apple-designed codec but i’m not an Apple person, i have a PC and a Mac, have since i was 20, i’m agnostic. I just think AAC sounds great. And i’m a professional audio engineer.

[@SonicScoop]

I definitely agree that AAC tends to sound better than most MP3 codecs I've heard, and more so the lower the bitrate is. I'm not a fan of whatever codec Soundcloud is using either. Most of my consumer listening these days happens on Spotify at 320kbps, and it's hard to get better than that kind of thing for a consumer format. If only they were better about credits and liner notes! (Although there has been some progress in that area.) I was also quite happy with Apple Music in the past, though I think they are 256kbps. Also quite good. But lower bitrates and some streaming services (*cough Soundcloud cough*) definitely leave something to be desired for audible fidelity. Very best, Justin
