Digital Audio Basics: Audio Sample Rate and Bit Depth
https://www.izotope.com/en/learn/digital-audio-basics-sample-rate-and-bit-depth.html
The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear …
Explanation of 44.1 kHz CD sampling rate - Columbia University
http://www1.cs.columbia.edu/~hgs/audio/44.1.html
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. The sampling frequency is chosen somewhat higher than the Nyquist rate since practical filters neede to prevent aliasing have a finite slope. Digital audio tapes (DATs) use a sampling rate of 48 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. Over the years, a number of standards have developed; in digital media used for entertainment purposes, the two most common sampling frequencies are 44.1 kHz and 48 kHz.

The most common values for the sampling rate is the aforementioned 8kHz (most common for telephone communications), 44.1kHz (most common for music CDs), and 48kHz (most common for audio tracks in movies). Lower sampling rates mean less samples per second, which in turn mean less audio data, since there is a smaller number of sample points to represent the audio.

The standard sample rate used for audio CDs is 44.1 kilohertz (44,100 hertz). That means each second of a song on a CD contains 44,100 individual samples. When an analog sound, such as a vocal performance, is sampled at a rate of tens of thousands of times per second, the digital recording may be nearly indistinguishable from the original analog sound.

For years, the digital audio sample rate standards have been 44,100 Hz (44.1 kHz) and 48 kHz. However, as technology improves, 96 kHz and even 192 kHz sample rates are becoming common. These lower sample rates are used strictly for multimedia files. 32 kHz is generally used with 12-bit audio on DV.

The diagram above indicates that even at a sampling rate of 44.1 kHz (the CD rate), some audible frequencies, pictured in red, are attenuated by the filter. How much is attenuated is determined somewhat by the quality of the filter and its steepness (or 'Q').
High bitrate audio is overkill: CD quality is still great ...

You only need a sample rate of 44.1kHz. If you’ve looked at your music player’s information tab, you may notice some of your songs have sample rates of 44.1kHz, or 48kHz. You may also notice that your DAC or a phone like the LG V30 support files with sample rates up to 384kHz. That’s overkill.
