Explanation of 44.1 kHz CD sampling rate - Columbia University

Explanation of 44.1 kHz CD sampling rate. The CD sampling rate has to be larger than about 40 kHz to fulfill the Nyquist criterion that requires sampling at twice the maximum analog frequency, which is about 20 kHz for audio.

During a recent conference call discussing audio sampling rates, the question came up: Why do CDs use a sampling rate of 44.1 kHz? The 2 Most Common CD Sampling Rates: 44.1kHz & 48kH. First, a little background: When you sample an audio waveform, you have a choice as to how many samples you take per second.
Why 44.1 kHz? | Intelligent sound engineering

44.1 kHz, or 44,100 samples persecond, is perhaps the most popular sample rate used in digital audio, especially for music content. The short answer as to why it is so popular is simple; it was the sample rate chosen for the Compact Disc, and thus is the sample rate of much audio taken from CDs, and the default sample rate of much audio ...

Other audio sample rates: 48 kHz, 88.2 kHz, 96 kHz, etc. While 44.1 kHz is an acceptable audio sample rate for consumer audio, there are instances in which higher sample rates are used. Some were introduced during the early days of digital audio when powerful anti-aliasing filters were expensive. Moving the Nyquist frequency even higher allows ...
44.1kHz vs 48kHz Audio – Which Is Better? | Pro Tools ...

Last Thoughts on 44.1 kHz Versus 48 kHz Audio In the end, 44.1 kHz, 88.2 kHz, and 176.4 kHz sample rates remain the preferred options for studio recording when outputting to a CD. However, if your audio is to be used in a video or delivered on a digital format, 48 kHz and its derivatives may provide the better option.
What audio file format is used for CD audio files?
https://fileinfo.com/help/cd_audio
WAVE and AIFF are two audio formats that support 44.1 KHz, 16-bit, stereo audio, which is the standard audio specification used by audio CDs. They are also encoded with pulse code modulation (PCM), which is the same encoding used by CD audio tracks. Therefore, WAV and AIF files can be easily converted to audio tracks when burned to a CD.
audio - Why do we choose 44.1 kHz as recording sampling ...

That was at 44.1 kHz (or more precisely 44.056 kHz). So this would make it easy to transfer recordings, without resampling and interpolation, from the F1 to CD or in the other direction. My understanding of how it gets there is that the horizontal scan rate of NTSC TV was 15.750 kHz and 44.1 kHz is exactly 2.8 times that.

As an example, for an audio CD, an analog waveform is sampled 44.1 thousand times per second (or 44.1kHz), with dots that are 16 bits in size (bit depth). In other words, the digital audio standard for CD audio is 44.1 kHz / 16 bits. PCM Audio and Home Cinema. PCM audio is used in CD, DVD, Blu-ray, and other digital audio applications.
