    Researching this for my own spin on this topic... One error here that's crucial: 44.1 WAS NOT compatible with 29.97 (which is actually 30/1.001). The recorders used the old 60hz black and white standard. But if it's audio only, it didn't matter. 48kz works with NTSC by using a leap frame every 5 frames. So if it was audio for video, 48khz was standard. Audio alone, then 44.1khz is fine plus you can squeeze in about 5-6 min on a CD with no perceivable audio loss

      Thank you for stopping by while researching. You might also appreciate my 32 bit floating point video, the deepest dive on it you'll find online: ruclips.net/video/xyMUAWXjrhA/видео.html
      Around 1:35 I show the math and explain what they were able to get sample wise with 29.97. On screen I was showing something about 30FPS used to achieve 44.1K. This is why I talked about "close enough is good enough" because even at 29.97 analog provides enough samples to exceed human hearing frequency ranges. All the info is in this video, I just don't break it down deep on camera.
      It was when we went digital video that 48K became standard with audio without having to drop or leap. Well, with exception of the time code jumping from 59.29 to 1:00.02 and dropping 2 frames every minute.

      ​@@SoundSpeeds I don't think that's the complete story - it's a hard topic to research unless you get deep down into the weeds of audio engineering (like really deep) which I'm not really all that interested in. Now I'm not talking about what "sounds good" - because they're all the same as far as I'm concerned in that respect. The devil in the details is the engineering and how to make it all work...
      44.1 is definitely the number you arrive with even 60hz/50hz video recording. But on the earliest Sony Digital recorders around 1980 there was also an option of 44.096kHz for NTSC. CD recording standard just went with 44.1 - but if you wanted sync with NTSC - 44.096 was the correct number because 44.1 does not play nice with 29.97 - that would require 1471.47 samples per frame and with 47 being a prime number, there's no easy way of splitting that over the frames.
      As for the arrival of 48 - that happened long before digital video was even possible - Even before the 44.1 became solidified as a standard in the CD format (1982ish) - there were companies like Decca recording at 50khz (which was another option). 48kHz sort of found a grove in Europe (because it played nice with the broadcast audio standard at the time 32khz - 3:2 ratio) - lots of software had been developed in Europe for 48 (again from companies like Decca). 48khz worked PAL broadcast and for 24fps film... just good number...
      But for fitting 48 into 29.97 - that's slightly trickier - as you correctly pointed out - that's 1601.6 samples per frame. Problem there is you can't have a fraction of a sample per frame (probably because it's too prone to errors) - so you have to have a leap frame every 5 frames. I'm assuming it goes 1601/1601/1601/1601/1604 - or 8008 samples over 5 frames (or even other ways of distributing those extra frames).
      The other option would have been 50khz - NTSC would need leap frames every 3 frames but 24fps would be thrown off and you lose that capability with 32khz European broadcast. So 48 was the least trouble and it only affected us NTSC folks - and we were already used to having to make accommodations for our weird frame rate.
      By the time DAT arrived in 1987, this was already pretty established.
      This is where I was getting a lot of this info from - it's a bit hard to read for someone like me that isn't quite at the level of an engineer.

      I'll check it out. Weird how the technical end of it comes from a different angle than we did in the pro audio world.
      To me I think we missed a huge opportunity it to correct the framerates back to 30FPS or 24FPS when we went digital. It would have been so easy to do and all we'd have to say is "Analog was 29.97 or 23.976 and digital is 30 or 24." It would have been so easy to correct then.

    • @CyrilleBoucanogh
      @CyrilleBoucanogh 2 года назад +3

      @FroobTubeLIVE, 48 KHz is better for everything, because the transition filtering accuracy is more forgiving, so use it for every recording you make. The 44100 is not actual as CD audio is out of usage today. Higher sample rates like 96 KHz and 192 KHz or higher are better for acoustic instruments recording with good transient response. But they have sense only if you do not use dynamics compression. Higher sample rates are also used for accurate audio processing due to rounding errors caused by lower sample rates. Alliasing factor can be beaten only at very high rates, such as 768 KHz and higher. But oversampling is used in all advanced modern plugins to overcome aliasing.

      @@SoundSpeeds Unfortunately like many other musicians on Friday morning at 8 A.M. I snoozed on my Music Acoustics class, but the teacher wasn't as articulate as you. Your analysis helped me make a decision on equipment to purchase. I'd been looking at the Behringer Wing to be the center of my studio desires because it is such a great value for money and does stand alone and works well with DAW's. But was concerned about the sample rate at 48khz. It's all about what you can actually hear...and maybe feel. Oh, and the medium audio, video, or both huh. Do you have any videos about floating point? WING has 40-bit floating-point processing at 48kHz or 44.1kHz. As I understand it, the ceiling and floor are increased so you don't need to worry as much about what the gain is, just get to recording and adjust afterward. Thanks for your time, I appreciate it.

      Higher sample rates come in hand when doing slow motion audio recordings or when trying to resample high frequency sounds humans can't hear. For example, if you want to hear the way a bat's sonar sounds, you can't unless you record it with a microphone that pick up sounds up to 48kHz and use a 96k sample rate. Then you stretch out the sample rate thus slowing it down and then you can make out what bats sound like but a few octaves lower where you can hear it.

    • @balisaani
      @balisaani Год назад +1

      96kHz is also used by classical music producers for longevity (shelf life), in the event 24-96 becomes the new audio standard on all streaming/listening devices (smart TVs, iPhones, etc) one day, their albums (original sessions) are already at 24-96. Some people can hear the difference - between 44.1 and 96 - most cannot (certainly not on iPhone earbuds or Bluetooth headphones).

      Not really a myth. RUclips convert audio to 44.1K for streaming but it's like how I said in the video... if converting audio from one country's format to another country's format, it makes it easier to encode the audio evenly.

    Can the Human Ear hear the difference between 48k and 44.1k? Will they have a difference in Sound and depth when watching a movie at home, and listening to Music on fx Spotify? My friend Said that 48k would be better for listening to Music, but i can’t hear any difference what so ever

    • @SoundSpeeds
      @SoundSpeeds  4 года назад +1

      Great question and no, humans shouldn't be able to hear the difference. In blind tests, audiophiles haven't been able to tell. It's all about math and simplification for the numbers with exception of if you are doing slow motion sound. Recording at higher sample rates (like, 96K for example) and then slowing it down to half speed makes it 48K. In that case you'd need the higher sample rate and only in that circumstance would human be able to hear a difference between 44.1K and 48K and that would require a trained ear. At half speed, they would reproduce frequencies 11,025KHz and 12KHz so... trained ears.

    Thank you very much indeed for this extremely interesting video.
    CD format dates 1980, DAT format came some 7 years later. i wonder if when they decided for the DAT format they felt a need of increasing the sampling freq to 48k. Maybe professionals rated the CD format not good enough for high fidelity ? i can only say that a friend of mine with a very analog taste and a huge collection of high quality LPs cannot stand easily CDs but likes some dat copies of his LPs quite a lot. I am sure that the higher 48kHz sampling freq adds something nice to the sound. 45 minutes of music (the average duration of an LP) take 476 MB at 44,1 and 518MB at 48. Just a little more space. But i feel like the difference can be sensible. So the CD could contain a 16/48 recording of an LP analogue master easily. What a pity. What is lost is lost for ever. Asa i will have time (retirement) i would dedicate myself to recording. i love whole numbers ... i do not like 44.1 at all. It seems truncated to me. Also 48 is three times 16 as well said in the video. 16 bit dac chips were available from the very beginning. Again a real pity.

    • @SoundSpeeds
      @SoundSpeeds  4 года назад +1

      DAT isn't compressed like a CD is and that's probably what's appealing to your friend. Technically lossless although some data is lost in the the 16 bit quantization. People also don't appreciate air as much as they do a noise floor. There's a warmth that air adds and although it's on both 44.1 and 48K, you may notice it more on 48K.

      Alejandro Reyes That's actually a different creature altogether. In the case of NTSC framerate, back when TV was just black and white, it was 30 FPS. When they added color, they had to find a way to fit the color signal into the existing B&W signal. They had a few options to consider but the one that meant changing the least while remaining backwards compatible was to decrease framerate to 29.97 and hide the chroma in the signal. PAL and SECAM standards came along after color TV so they incorporated color into their signals without framerate changing fr a whole number.

    • @Soundgrains
      @Soundgrains 7 лет назад +2

      24-bit audio having a high resolution than 16-bit audio reduces the error created during the sample quantization process. That error is manifested in the audio as quantization error noise. Quantization error noise sounds like tape hiss. The greater the error due to quantization, the more audible the noise, thus a higher noise floor.
      The noise floor of 16-bit is generally too low to be audible in a track that has good levels. The key against noise in a recording is signal to quantization error noise ratio. 8-bit audio has a very audible noise floor at ~-48dBFS without dither and noise shaping. Recording in 24-bit (~-144dBFS) reduces the need to record close to the point of clipping (0dBFS) and is thus preferred during the recording process. If you record with 16-bits (~-96dBFS) with a peak of -16dBFS then your effective signal to quantization error noise ratio is only 80dBFS. With dynamics processing such as dynamics compression, this dynamic range will be reduced and could possibly become audible (although this is rare).
      That being said, 24-bit audio is most useful during the production stage. 16-bit audio is sufficient for most general consumption as ambient noise would be the bigger issue. But with proper gain staging and recording levels, there is nothing wrong with using 16-bit audio recording.

    What does 2000 mean here, like 20.0 FPS, 19.20FPS, 20.0FPS and 16.01FPS?

      It doesn't mean anything. Is just a joke round number which means consistent number of samples frame.
      EDIT: That was a typo. Should have read "It was just a nice round number".

      @@SoundSpeeds try to keep this type of jokes aside, I'm programmer literally I grab any type of information as serious matters.
      Then imagine some guy making an article later in Reddit about how he found the "magic FPS numbers"

      No, that wasn't a joke. It was a typo. It should have read "just a nice round nunber".

      You're probably not killing them but instead talking dirty to them.

      In the Hebrew alphabet which every letter equals a number which is called gematria. Was used in Greece as well. The first letter the middle letter and the last letter of the entire alphabet adds up to 441. Each letter is a vibration of sound and a collection of letters create a name of something. Hence all sounds that can be heard within human hearing is within the spectrum of the Hebrew alphabet. Just a fun fact I noticed.

      You can use 48K for music only but you won't gain anything.

    Seems like legacy formats are ready to be retired. 48Khz, 24bit sounds great, then again 80's metal, diesel engines, and people screaming in my ears diminished my hearing 😡
