[@pbholmen]

I've been dabbling into DSP myself, and I'd like some more info about this. I understand the basics of harmonic distortion and I understand what aliasing is. But does this unwanted effect, of reflected frequencies, happen due to processing in the time domain or in the frequency domain? I haven't tried to make a saturation plugin myself, but I'd imagine I would simply limit each sample in the time domain, with a transfer function that compresses the curve towards the extremes, so that a sinusoid would start to approach a square wave. Surely this would add third order harmonic distortion, but wouldn't cause any aliasing, would it? Sure, if I kept on adding odd harmonic sinusoids, and went above nq frequency, then there would be aliasing, but why would I do that? As you sure can tell, I haven't actually done any non-linear processing (coding) myself... :)

Furthermore, changing the speed of a sound is basically one of the easiest ways of transforming it and making it unrecognizable, hence giving you creative options.

[@Hamachingo]

@@thorwaldjohanson2526 Auto-tune. The way it works is that it cuts audio into the tiniest chunks and sort of copy-pastes them and stretches them to alter pitch, length and vibrato. With 44.1 kHz, it sounds weird very quickly even with very mild auto-tuning. Even just having the recording in 48 kHz makes a big difference in my experience, now you can get away with correcting pitch and timing without it being noticeable. 96 kHz allows for extreme stuff if you're into that, but if you got somewhat capable musicians and are only fixing a few off notes or beats, 48 kHz works well for me (in Logic's own auo-tune system).

[@thorwaldjohanson2526]

@@Hamachingo Thanks for the responses guys :). I'm curious, are you usually recording in 192khz 24bit and then downsample if need be, or do you start directly with 48khz? Or do you record different instruments at different settings? And are there any disadvantages besides filesize, to record at the maximum bitrate?

[@Baphometrix]

I've been a strong proponent of working at 44.1 project sample rates for over a decade. Based largely on the understanding that most music producers have sample libraries comprising 44.1 samples, and that crappy realtime SRC up to 48 inside most DAWs was incurring a needless quality loss from the minimum phase anti-aliasing filter during realtime SRC. But your explanation of the cumulative effect of many oversampling stages with a gentler anti-aliasing filter at 48 has opened my eyes. Your A-B comparison at the end, of 44.1 oversampled versus 48 oversampled across the entire project was mind-boggling. My hearing is relatively destroyed at this point in my career, but even with my trashed ears, I can clearly hear the difference in that final AB demonstration. I would never have had the patience to set up a test project of that size to show the cumulative difference at 48 vs 44.1 like that. THANK YOU. (I'll be working at 48000 project rates from now on, despite the fact that I don't do soundtrack work and my sample library comprises mostly 44.1 samples.)

[@Baphometrix]

@Agent К_видео The difference is subtle, and falls into the category of "ear training" for certain things, plus a LOT depends on your monitors and room characteristics (or your headphones). I'm used to listening for "how much clipping is too much clipping" because I use clippers a lot and push limiters hard. The aliasing artifacts and IMD in the 44100 version has some similar "dirt" and "grit" around the edges of the transient sounds in the mix (like with clipping), and the mids and highs feel a little more "congested". By contrast, the 48000 version has a more "open" feeling in the mids and highs, and not as much of that dirty/gritty edge to the transients.

[@user-bo8ex4ji7n]

@@Baphometrix Agree with your assessment and my opinion was that neither were necessarily "better" I listened to the comparison with different sets of monitors, and for some it felt like the 44.1 version with OS was slightly more mid/low-mid forward and it made it feel like a more focused mix. No doubt that the 48 one felt a bit wider/open, but that's not always what I want/need in a mix.

I think you missed the point of that final comparison, which was that the A/B differences were negligible. I think the changeable nature of the music made it harder to notice the lack of difference between the formats.

Thank you, thank you, thank you, thank you. I've been telling people (mostly amateur engineers and audiophiles) this stuff for years but this is the first video I've seen that actually illustrates it perfectly with smart examples and incontrovertible proof. High sample rates for the final, consumer delivery format are useless. Even for basic tracking, they don't really matter because the majority of microphones don't pick up much of anything over 18k anyway. The only reason to use them is in mixing and it is far more practical to just use over-sampling rather than record everything at a higher sample rate. Dan Worrell is the best.

[@jeff92k7]

Great video and explanation. Matches up with what I've been doing for years. I record and edit/mix almost everything at 48kHz. With popular music, the space and processing savings of 48k are noticeable and any harmonic content above 20k is pretty much buried under other instruments anyway. Plus, producing high sample rate content is pointless anyway since pretty much all forms of music compression (size) will bandpass limit the content anyway before applying the lossy compression. However, there is still one thing that I record and edit at higher sample rates - that being orchestral music. With typically few microphones (allowing acoustic mixing of the band/orchestra prior to microphone capture), the space and processing savings is unnecessary. There are some instruments that do have harmonics, and even natural energy, above 20k. I find it best to capture and edit at the higher sample rates and then apply bandwidth filters upon final mixdown. This avoids the issue of those frequencies above 20k turning into aliased content in the below 20k range during initial tracking/capture or in the editing stage.

[@squidcaps4308]

Aligns with my own experiences and lessons over the years: bandpass everything, all audio is bandpassed at some stage anyway so you better do it.. before it is too late and the signal encounters something that can't cope with its demands. Distortion and heat will be the result of that and you will get degraded audio signal. Also: Hi-res record releases are not meant for consumer consumption, you once again have to deal with bandpassing the signal before it hits your speaker. The end result is intermodulation distortion in the analog chain too. Most of it will be turned to heat but it is never a good idea to push too wide of a sausage thru a too small hole... A good speaker has ultra- and infrasonic filtering but one of the principles i have picked out is that it is far better to cut the signal before amplification than after. If for nothing else, components are smaller and the circuit design can be considerably better.

[@Rhuggins]

I hope one day to be as wise as you 🙏🏽

[@JohnnyNatrium]

About these high res 'record' releases (I'm assuming digitized recordings of analog master tape playback then of course, just stating this because in common parlance the term record is often read as synonymous with vinyl plate prints); To deny that they are *meant* for consumer consumption (as opposed to what consumption?) is simply contrarian. You know about these releases, so you must know that their resellers have a consumer demographic. I consume, as a consumer - which includes every producer because none of us only uses music materials for work aka in your terms "producer production": just to source, process, stock etc. - I consume hi-res consumer content recreationally, like the vast majority of their target demographics. And I'm not sure if you're simply generalizing a part of this market, or if you're making a case against the release of hi-res digitizations of any music source material, for any recreational consumers. Certainly when taking what you're saying literally, that is what you are doing; but of course communication is too complex to know for sure. In any case, consider the consumption of hi-res releases, by a consumer who bit-streams it to a high quality digital-to-analog converter, going into an analog (pre)amplifier which easily handles the output signal of the aforementioned converter, ending up, in any circumstance which assumes no use of destructive ignorent elements in the signal chain between, playing back through high quality speakers or headphones. What about this is 'not meant' to be?

Dan, for years, I have searched for this conclusion. I spent two weeks chasing my tail trying to mix a solo acoustic guitar song: each corrective tweak created more deficiencies than what it solved. No matter what I did to "improve" the mix, it simply sounded like there were both dead spots and artificial bright spots that nothing could fix. After watching this video, I tried a 'what-if'. I lowered the DAW session sample rate from 96kHz to 48kHz and made no other adjustments. Immediately, as if someone flicked on the sonic fullness switch, my mix sprang to life. Life will never be the same, thanks to this video. 48 kHz is my new sample rate. If a project calls for a track to make its way into the movie domain, I will simply upsample the 48 kHz master to 96 kHz to meet that format. Thank you for this most excellent 'put the sample-rate argument to bed' video. Keep up the good work!

[@JohnnyNatrium]

This video demonstrated that you will hear a difference, assuming you apply digital processing of the signal to a common degree. What did you think the point was of him advocating the use of functions which use 8x the project sample rate, featured in the distortion plugins?? It just also demonstrated that you're better off using higher sample rates on a per-process/plugin basis, to avoid using resources on processes which cannot benefit from it (meaning not setting your entire project sample rate, based on the highest denominator which is your most aliasing-prone plugin(s) because it affects the CPU power needed for everything which doesn't audibly affect the signal as well. This has always been the case in out-of-the-box processing, because every analog signal processor, such as the type of distortions he's emulating here, was already 'upsampled' separately, by way of being an analog process, while the drum machine that the band used, was not unnecessarily digitally upsampled at the source, or at any digital point in the chain that didn't benefit from upsampling. But you will certainly hear the difference when you apply a digital process that aims to recreate the type of analog warmth that these distortion DSPs are doing. He's literally explained to you that you want very high sample rates for that type of processing, just that it's handy to have this function available and contained within each plugin, which in effect is just a way of getting closer to the way out-of-the-box mixing and mastering is done, assuming the inclusion of analog gear, which is virtually any music that isn't chiptunes.

Thanks so much for helping us mortals with a proper technical explanation of when and where oversampling should be used. Also love the plugs!!!

[@andremigcasol]

in case anyone wondered, youtube is cutting at around 15k or 16k (so you might still hear 20k Hz)

[@masis3256]

Oof I nearly forgot

[@peterselie1779]

Not for all videos. This video uses the Opus codec with a 20 kHz filter. The 20 kHz tone at 4:59 is actually clearly there (I checked with a spectrum analyser), allbeit a bit attenuated.

[@TheAnotherOSC]

Check the stream you're receiving on the "Stats for nerds" option. If you're receiving an opus stream, you're fine.

[@nexusobserve]

bandwidth limiting when using multiple stages of distortion to prevent aliasing.... that's what i've been doing! also it is incredible how much of a different 41.1 to 48 makes this is an amazing demonstration

This is absolutely incredible holy shit. Finally, i actually understand this shit. Your ability to break this stuff down is actually amazing. Adding vibrato to show the aliasing? Brilliant. Thank you sir 👍🏻

If there’s a lot of pitching shifting and tempo change in the project higher sample rate may be beneficial

[@maaaquemeseyo]

It’s the third or fourth time that I’ve seen this video. Every time has blown my mind. Stellar.

[@ezrabrownstein3237]

The increase in depth and separation with the oversampled version is a astounding, even with the lossy mp3 playback over KZbin. I thought when you switched to 48k I wasn't going to be able to hear it but I was blown away again by just how much more separation presented itself in the high end especially.

[@BojanBojovic]

I am not able to hear any difference.

[@flash001USA]

This was a great video and you broke it down in layman's terms where people could grasp the concept. In reality the better the original recordings are captured or managed can also play a very important role in eliminating some of these issues you are pointing out especially if it means being able to use less plugins. In my home studio I try to use plugins sparingly not only to limit how much processing power is required by the computer but just to keep things simpler. I also run a Hybrid DAW station with an analog mixer with the option to run external compressors and limiters when needed which allows me to capture a really decent analog drum mix where the DAW can be just more of a multi-track recorder and the same goes for capturing bass guitar and using an external compressor/limiter rather than using plugins to manage the bass guitar's dynamics and as long as you're mindful of the gains during recording, you're golden. For me and my needs this works but for a modern day commercial recording studio this probably wouldn't fly or at the least they would be limited especially dealing with many different styles of music due to the dynamics they may see like speed metal vs classical music along with music production for a movie etc and the effects required to make it deliver.

This video is a staple in the hi-res audio debate of whether it's actually worth anything, and you do a great job at explaining how it's mostly just a bunch of people who don't know the details who obsess over hi-res. For example, I was one of those people, and then I watched this video lol.

[@rfpm]

The point is made at the end that higher sample rates can result in a higher chance of increased intermodulation (lower quality content), is this touched on at any other point in the video? Also he said that "higher samples rates do nothing to improve the quality of audible content below 20khz" isn't this contradicting what was shown earlier in the video in Acustica? Really great video by the way, I loved it.

[@ImpostorModanica]

Good question

[@gijscoolen6439]

He touched on this when using multiple instances of harmonics-generating plugins (saturation, compression) in a row: even at 96kHz the first plugin adds harmonics that will 'bounce back' off the nyquist freq. The second plugin then generates harmonics off of those 'false' harmonics and so on. The reason the chance of this happening more often in higher samplerates is human error: because you tend to not worry about aliasing and thus don't turn on the oversampling algo because you're already working in a high samplerate (so you think..) Or at least, that's how I understood it...

[@rfpm]

@@gijscoolen6439 Ah ok, yeah it's the reasoning behind it being said that higher sample rates can be lower quality that puzzles me. Seemed to imply more than just forgetting to use oversampling. The statement "higher samples rates do nothing to improve the quality of audible content below 20khz" as mentioned in my first comment still puzzles me too.

[@heavysystemsinc.]

I think the point is that increasing samplerate doesn't automagically mean better audio fidelity and cleaner signals. A lot of things have to align in the stars (as it were) for this to 'just happen' and that no matter what, with digital audio, you're going to have work around how digital audio naturally exists. Also, the point he made about increasing the sample rate was also that you'll use far more CPU with marginal results in many cases. It's like the differences between 4k computer monitor and 8k computer monitor. Your computer has to work 4 times as hard to give you a picture that literally no one can tell the difference unless it's blown up to the size of a movie theater screen and even then you'll only notice the difference once you get 5 feet from it, and no one likes watching a movie theater screen from 5 feet away.

Honesty one of the best videos about this, thank you.

[@simonslee73]

Amazing video! Could you also do the same video for resolution as that has the same myths. So many DAWs support 32bit floating now but so many still use 24bit. Would be great to know the math behind this as well.

[@ncshuriken]

My leaked experimental version of Ableton 13 supports 64bit flying point audio which it isn't even possible to record at yet, except on the prototype interface I stole from MI5's top secret recording studio (2 miles below London underground) when the guards were distracted by a girly mag I threw on the floor, so I'll see y'all later!

[@njleeusa4035]

@@ncshuriken Reaper records in 64 bit FP

[@JoeStuffzAlt]

CPUs might actually handle 32-bit float better than 24-bit int depending on the algorithm. 24-bit actually has a ton of information, you probably won't hear it the difference, but I would not say the word "always" when it comes to computers There's a good chance some DAWs will store 24-bit samples as 32-bit integers since CPUs handling 32-bit data better than 24-bit, plus it would increase mixing quality

[@jarcau_vegan]

20:15 This dance makes me think about how most of the content in DNA is just mere historical aliasing.

[@manniesingh2738]

What a beautiful description, wow.

[@einarabelc5]

So you want to attribute the boundaries of Nyquist to DNA, huh?

[@jarcau_vegan]

Hi, well, that's an interesting question. I'd say that I can't do that, because it is Nyquist who theorized about boundaries, and these boundaries must be attributed only to him. DNA is just a container of lots of aliasing, not the boundary between this aliasing and the contained meaningful information. So, the noise to signal ratio is strong, intense and loud in DNA. To the point it clips my mind. But not in human DNA... Human DNA is untouchable, superior, super-superior. It is sacred. It is beyond Nyquist. Human DNA's undetunned and high pitched frequencies makes us to be born with the ability to think that all that there is in the Universe belongs to us. Sorry for the rant... I'm still learning to balance in LUFS. Hope this helps. LUF 🍀
