What is High-Resolution Audio?

[@alexxander3436]

The audio on this video is screwed it self 😂😂😂😂

[@FernieCanto]

+OhNoItsGojira Informative, yet contradictory. The video itself said that the CD format is more than sufficient to capture all the range of audible sound, yet tries to convince us that reproducing ultrasonic frequencies, inaudible to humans, make any difference, and that you need more than 16 bits to hear "the tapping of a pianist's fingernails". It tries to create a difference between "hearing" and "experiencing", suggesting that Hi-Res audio will compensate for all the loss of quality you get from the shitty mastering and production in recent professional recordings. The snake oil is strong in this one.

[@raffiequler7510]

You are very ignorant. The frequencies above 20 kHz have a huge influence on what goes below 20 kHz. The sound of a studio master file is always thicker, warmer, more spacious and more dynamic.

It’s a waste of bandwidth and server storage. KZbin is a video streaming service first and foremost, not a music streaming service. (And not a very good one, at that) Both their video and audio compression is quite lossy. They have so much more content to store and stream compared to the ‘competition’ in video streaming services (Netflix etc), and have less of a need for high quality video and audio. Personally I’d like to see KZbin improve their video compression before allowing bandwidth hogging lossless audio.

[@judenihal]

"let's make a video about high end audio. let's use the cheapest microphone we can find to record it..."

[@dvamateur]

It's ironic, because Hi-Res audio is better, but not for the reasons mentioned in this video. That's the sad part about advertising... To put it short, Hi-Res audio has tremendous advantage for hardware design like the D/A converters. High sampling rate of 192kHz or more is not to reproduce frequencies above hearing range, it's to eliminate the interpolated noise we have insert in between the samples in regular CD audio D/A conversion (recovery) stage. And we have to insert a lot of noise. 64x times that of original information. It's outrageous. We are still fooled though. To put it in simple terms, D/A converter of a CD player is conning us big time. With Hi-Res audio, we don't need to insert as much noise in between the samples, because the sample gaps are smaller. In fact, in DSD codec (sample rate of 2.8224MHz) we don't need add any noise. But I digress... To put it simple, Hi-Res audio is more truth to the honest storing of the actual audio information that was recorded by the A/D converter. In other words, Hi-Res is less of a scam than CD audio.] Do we need more than 16-bits? Yes, we need a few more bits than that, but not to represent 144dB volumes, that would be pain our ears would not handle. We need those extra bits to represent the quiet (pianissimo) parts of a musical piece. Great thing for the classical buffs. You don't believe me we lose resolution on a CD for quite parts? Find a song with a fade away ending. Then crank up the ending, you'll hear graininess in the sound. That's because you might end up with like 4-bits of resolution for the quiet parts. I am not saying you should listen to song fade aways. I am saying this is useful for classical music pianissimo parts (or good jazz piano, you know stuff like that). These are all valid reasons for higher sampling rates and higher bit resolutions, which Hi-Res audio provides. Hi-Res also eliminates the need of near brick wall filter at the A/D stage. It's not really a square brick, the filter has some slope. When we're recording into 44.1kHz digital audio, we start rolling off frequencies above 20kHz. The reason we use 44.1kHz and not 40kHz sampling rate, is so that we have space for the filter slope. Yes, we use that extra 2.05kHz above 20kHz just for that. With Hi-Res we don't need that steep of a filter. We can process all frequencies, even 40kHz, without them folding back into the audio range (aliasing). It's fantastic. Hi-Res is a great thing. Sony advertises it wrong... It's sad.

Well, accurate more or less. I'd still want to believe that an ultrasonic whistle can have influence on us. I mean, you can't hear it, but boy, doesn't that thing vibrate and buzz in your mouth? Also, ultra high frequencies, being very high harmonics, might have an impact of our perception on the overal timbre. I believe harmonics are infinite in nature, so we won't capture all, but why not capture most if we can? I am a simple man. I am looking for the most truth to the honest digital audio encoding. Truth doesn't exist in science of course. But I think we should try our best to get as close as possible, with good intentions and all.

44.1khz at 16-bit was chosen for a reason. The frequency is high enough to exactly reproduce any human audible frequency, and the bit _depth_ (not bit rate Sony) is high enough that there is effectively no noise.

Going above 44.1khz and above 16bit resolution is just useful to work with audio (like using RAW to edit pictures), it doesn't improve listening experience. Human hearing highest frequency is at 20Khz, which 44.1khz sample rate files can record and play perfectly.

Though you could skip this part and just re encode it to 44.1Khz 16 bit lossless file (uncompressed wav or flac). Now ask someone to put yo some headphones and ask that person to play a few seconds of one of the two files that the person will choose without you knowing which. Try to guess which one is and have the person take note of your guess. Repeat this multiple times (try let's say 10). I'm sure at the end of it, you will guess correctly nearly half of the time. This experiment has already been done with experienced audio engineers and the result was that they could only guess correctly 49.6% of the time. Google about it.

[@dumbpublichater9365]

This is baad marketing. 1) 96 db should be absolutely sufficient dynamic range for any consumer application, audio is compressed when it is produced to much lower range, and I dont speak only about squeezed dubstep. Ok, some very quiet part of classical recording can benefit from lower noise. 2) Again, consumer doesnt hear over 20, not even 18 unles it is child. There is *hypothesis* , that if the hardware is able to produce the high frequencies, and if the hi res oversampled format is used, and if the recording actually *contains* that high information, then the high overtones can backwards influence those closer to the fundamental and actually change the *perception* of the hearable tones. It is difficult to test it though, bcs comparing two identical files in audible range, one of them having low pass somewhere obviusly make them sound different due to the missing content on one of them, however, it is not possible to state whether the perception of low information which is shared actually varies comparing them. And to be able to even try to perform this test with hi freq-hi res audio we would need a dog to tell us.

The former is sampling rate for music, which you need in order to capture the multiple, simultaneous soundwaves that a song has. The latter is, as you mentioned, the frequency spectrum that a young, healthy human ear can capture and detect.

[@peterselie1779]

Because the CD was designed when sony still had honest sound engineers who knew 44.1 kHz / 16 bit PCM is enough to recreate the human audible range fully without any perceivable artifacts whatsoever. DVD has 48 kHz audio, because 48 kHz divides evenly by all the commonly used frame rates (24, 25, 30, 50, 60 fps) for video, which allows a fixed number of audio samples per video frame, which is handy. Blu-ray was designed for dolphins, appearantly.

Just sharing my experience. I bought some songs from HiRes website. Then I compare the song with CD version. Did I hear the difference? Yes, for only some of them. Ok, hmm.... HiRes is true then! So I tried another approach. I down sample the 24/192 to 16/44.1 with software, and I compare the down sampled with CD again, did I hear the difference? Yes! So lets compare the down sampled version to original purchased version, hmm...... I cant really hear any difference among them. So what? Hi Res, seems like just a remastered version of the same music, and purposely push up the sampling and bit rate and then tell the customers, Hey! Because it is BIG, so it is BETTER!

[@arwlyx]

I think the real advantage with buying hi-res audio is the fact that it was mastered differently for that audience, without the DR compression, with the bonus that it carries less guesswork to be made by reconstruction algorithms due to the higher sample rate. Also be aware that you cannot see the advantages of superior audio files without proper hardware to do so, going from onboard audio on my motherboard to a sound card and entry level studio headphones made me see the quality difference between files that I couldn't see before, even the MP3 files sounded better by upgrading those two.

[@BavarianM]

Wrong

[@HughCorner]

Using a phrase like "high definition" for audio is misleading because it makes people think they're getting extra detail when they're not. 1) all using a bit depth of 24 bits does is lower the noise floor, which is inaudible at 16bit anyway, and 2) the standard CD snapping rate of 44kHz is more than enough samples to capture the frequency range of human hearing. Tl;Dr - all "high resolution" audio does is cost more money and take up more disk space without improving the detectable quality of the sound at all.

[@MacSvensson]

Well they are and they aren't. Whether you can see the difference between fullHD or 4K images or not, is irrelevant. There is more detail in a 4K image. That's a fact. Same for HD audio. Just stating facts. Whether the receiver aka. the human ear can hear a difference, is - technically speaking - irrelevant.24 bits compared to 16 bits doesn't only lower the noise floor, it also captures the correct 'loudness' for a particular frequency better. There's a significant difference between 65K and 16M+ levels. Ofc, you are right when you say it wouldn't make a difference in most cases. It takes high end materials and apparatus throughout the entire chain for it to stay relevant. Good amp, good speakers, good wires, and a good ear. So in that regard, you're probably correct.

[@kacperuminski1547]

@@MacSvensson Formats capable of reproducing frequencies of over 20kHz actually harm fidelity since equipment often suffers from intermodulation distortion which only manifests if you try to make high frequencies go. All higher bitrates do is minimize quantization during recording which is basically rounding the loudness to the nearest value. Quantization adds noise which is avoided when using a higher bitrate. Doing that is however unnecessary since you the noise is already about -100dB under the signal which is enough for all musical recordings.

[@Jadinandrews]

Sampling rate is not just about reproducing frequencies, it also allows accurate phase differences between two channels to reproduce 3d effects better. Although our brains only discern tones up to about 20khz, they are much more precise in discerning arrival differences between the ears. This information is filtered by completely different circuitry in the brain which is why we can instantly pinpoint the location of a sound in the real world. Even the best binaural recordings lack realism and depth. To add to this, it has been shown that the average human has a temporal resolution of around 8-10 micro seconds which corresponds to a frequency response of around 120khz. To be clear, you do not 'hear' this information, your brain just 'positions' it.

If that's true, then why would you need a much higher sampling rate and higher bit-depth if they exceed these measures that are supposedly already enough? Also, digital streaming services like Apple Music and Spotify actually offer almost CD-quality playback.

The question as to whether high res audio is worth having is.. Do sound frequencies we can't hear interact with sound frequencies we can hear? That would be the only reason it would sound better.

[@etmax1]

The compression method that MP3 uses is called lossy because it drops a lot of info in a manner that our ears don't "easily" notice, but how much is lost depends on the sample rate used. AAC which is I think essentially MP4 but with Apple specific settings is considered lossless so even though it's compressed it shouldn't sound any different to CD. Now High Res will sound better but if you want to be able to hear the difference then you would need to invest in a very expensive amplifier and speakers to have any chance. Yes you are right to ask question of whether it's worth it, and I would say no. It's like a 0.01% improvement.

[@warlockboyburns]

​@@etmax1 High res matters less for acoustic music because the sound frequencies interact with each other producing the final sound that the artist was hearing before they are recorded by the microphone, with electronic music/electric guitar the sound frequencies don't get a chance to interact with each other so any loss of detail means we don't hear what the artist was hearing. Sound frequencies interact with each other. Ideally electronic should be recorded from pa speakers/monitors with microphones in my opinion.

If the master is designed for high res then by math alone you get more information to enjoy and by that I am not talking about freq's above 20khz.

If I am old and my eyes are bad I can't see everything clearly but I can see that there are more details than the flat low res picture. The same with sound. I decided to test this myself a while back and what I find is high res brings the symbols clarity and the jazz drum brushes or a hit on the rim of the drum where on lower res I couldn't make this out on a hi res created file. Digitally a hi res player will recreate the hi res created sound and likewise a normal res player will not bring out these details digitally. I would not attempt to compare Vinyl since that format has all the high res detail in its design range available to hear when you push it out a good turntable, speakers and amp.

Your speaker impedance is 8 ohm, average of 6.8R with a dip to 4.5R and a rise to 10R still well in the audio bank (10kHz ish area). The voltage drop of the drive signal along the cable will change with the load impedance. We are outside of any feedback loop so this is an un-correctable error. Ohms law, so irrefutable. This difference in impedance for the above is 196bits at full signal. IE if we drove a full 16bit encoded sine wave at the 4.5R frequency and again at the 10R frequency, the 4.5R tone would be smaller by an equivalent of 196 bits due to the additional voltage drop over the speaker cable. The point I am making is to get 16bits resolution through a real world system is next to impossible, so 24bits is _fairly_ pointless. It isn't just speaker cable, the temperture drift of your volume pot or left / right mismatch makes the speaker cable issue look small. THe whole system just chips away and you can not avoid it.

In electronic/line input music high res should sound better because frequencies we can't hear interact with frequencies we can hear which only happens through our speakers but in acoustic/mic recorded music that process already takes place through the air before its received by the microphone (not that acoustic instruments have frequencies lower or higher than our hearing). So to guarantee we hear what an electronic artist hears (or more) we need to have high res

I'll give you a hint: 16-bit/44.1 kHz is an optimal end-user format; its limitations exceed perceptual human hearing. "High-res" formats deliver no tangible benefit to end-users. Such formats are only useful in a studio environment, i.e. during recording and mixing.

[@MrSpitfire06]

Actually there's a difference it's call dynamic. The High Res is not there to actually give a greatest quality of sound but a greatest RESOLUTION. When you hear a sound in real life, there's no such things as formats or compression. High Res is a way to listen to music like the fucking instruments are in the same room as you cause the sound is much more "realistic" with more dynamics. That's all, you hear harmonics above the 20 Khz cause a sound is form by these harmonics

[@petersimonsen4985]

[@RizkhyDestatama]

the media and format means nothing if the data itself (the music) is created in a bad way. 16 bit on CD capture a lot of dynamic range, yet modern music made with less dynamic, wherever you put that file, it will be sound the same. now there is more advance format Hi-Res, if the music itself mastered in a bad way what's the point of having higher dynamic range if the label does not produce music that way. the weird thing is is sound better because the music mastered differently, look at the DB database it's clear that the vinyl have greater dynamic than CD, even though CD should be better because it has lower noise floor.

Sony, once was an innovator using science to push the envelope. They, with Phillips, developed the compact disc and through the 1970s, 80s, 90s and 00s were had revered products both for home audio and the studio. How sad is it now Sony resorts to marketing and psuedoscience, trashing their legacy in the process. If Sony was really interested in natural sound, rather than pushing hi res, which has no sonic advantages over CD for human beings, they would stop releasing brick-walled, squashed, loudness wars type of recordings from their remastered music catalogue.

[@stp22]

Today a WAV rip of a CD is called HiRes audio. After 20 years of crap FM, cassette and MP3 of course good old CD file size sounds great.

Nyquist sampling rate is the minimum requirements to reproduce a single frequency sine wave. it's not enough to reproduce complex mix of music. usually you need 20x to reconstruct an analogue signal with DAC.

[@AynkaranRamachandiran]

Çerastes What i meant is, If the sampling is done in 2x the highest frequency, it will be 4 samples to reconstruct the highest frequency, which is not enough. In my opinion, at least 20 samples required to closely reconstruct the highest frequency.

HiRes makes no sense, because the human ear is not able to differentiate between "regular" lossless and hi-def. The CD standard fully covers the whole spectrum perceivable by humans. Worse, as some sound engineers will tell you, hidef can actually introduce errors.

Virtually every modern CD has OVER-compression of dynamic range. If this stupid loudness war was stopped, then we'd have no need for any format above 16/44 - heck, I'd estimate that most contemporary albums use about 2 - 3 bits of dynamics!

[@ezrazski]

false -- the format is different than any loudness war. loudness is a constant battle between air and volume for that particular format. the format going up to hi-res could decrease the loudness war but it's no guarantee. they aren't that interdependent.

[@ariellewest5024]

What’s put on a cd is up to the mastering engineer not the limitations of the physical medium. If you want loud we can push the levels up to where you’re getting a square wave instead of a regular sign wave is not the fault of the CD.

Hi-Res - Sony reinventing the wheel for dummies with mp3. DSD, 24/96k was available 25 years ago with Meridian Audio doing a lot research on Hi-Res.

I think it has more to do with the quality of the actual recording than number of bits or sampling of the final product.

[@zogzog1063]

Pretty decent effort - I will give you a like despite this being pitched at the adolescent level. The fundamental points not addressed is why (a) 24 bit are better (at least from a sound engineering point of view) and (b) how the higher frequency sounds better (and I believe it does) despite CD quality (aka Redbook) being beyond the limit of human hearing.

[@emmanuelpoirier4602]

hd is higher resolution which means more info recorded and reproduced which means more energy and more energy nuance felt. You don't just hear with your ears but with your whole body as your cells are communicating with frequencies see How cells work by Bruce Lipton. So that means higher quality music means better health. Remember that when scientists measured the ear bandwidth they had certain tools to do so, those have evolved. Also when ear capabilities measurements where done scientists had certain presupposed hypothesis in mind, those are gone and where back then too: that's why audio engineers have recorded music at a far higher resolution than CD a long time ago. Don't believe you have limits, you have none. Science don't know everything, it keeps learning all the time.

[@maxiemoon92]

High res can help the interpolation and reconstruction process of a dac but besides that high res isn’t very useful. CD quality was built to the spec of the auditory system as long as that information is reconstructed back into a wave form correctly there shouldn’t be a difference 🤔 IDK Sony 🤷‍♂️

[@bustersgotavmax]

If only these companies concentrated on good quality Mastering for their digital releases, instead of ignoring the subject. I buy high res pretty regularly now from hdtracks and find the biggest sound difference is in mastering and not as much the difference in sample rate from CD quality to 24/96.

Some do some don't. The music I listen to sounds awesome but I only listen to mainstream artist which tend to have the best mastering processes

[@TurntBucket]

so i get why a recording format can be labeled hi-res (as it is converting analog signal to a digital one with some specific resolution) but what does that have to do with speakers being hi-res? a speaker is already receiving the analog signal. Does calling the speaker hi-res just mean that it produces the amplitude of sounds more accurately and has a wider dynamic range it can reproduce than speakers that would not qualify as "hi-res"?
