What is the sample rate for CDs? – Easierwithpractice.com
https://easierwithpractice.com/what-is-the-sample-rate-for-cds/
Most digital audio has a sampling rate of 44.1kHz, which is also the sampling rate for audio CDs. This means that the audio is sampled 44,100 times per second during recording. When the audio is played, the hardware then reconstructs the sound 44,100 times per second. Those individual samples vary in the amount of information they have.
Explanation of 44.1 kHz CD sampling rate - Columbia University
http://www1.cs.columbia.edu/~hgs/audio/44.1.html
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. It has been claimed that thier sampling rate differs from that of CDs to make digital copying from one to the other more difficult. 48 kHz is, in ...

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 ...

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 sampling rate is chosen for a certain application depending on what acoustic artifacts need to be captured.
Understanding Audio Quality: Bit Rate, Sample Rate ...

Higher the bit rate with more sampling rate, requires high bandwidth and produces good audio quality. Low bit rates refer to smaller file size and less bandwidth with a drop in audio quality. For good quality music usually 64-128kbps(96kbps+ recommended) bit rate is preferred. Sample Rate is the number of samples per unit time. A sample is a ...
Digital Audio Basics: Audio Sample Rate and Bit Depth

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 ...

You need a sampling rate with more than twice the highest frequency component. But how do you know the "highest frequency component" .. let's say in an audio signal. Somewhere it is said that audio frequencies go up to 20000Hz. So you need a sample frequence higher than 40kHz. For the audio CD standard 44.1kHz is chosen.
Upsampling or Oversampling? | Stereophile.com

(Because of its association with DVD-Audio, 96kHz is often chosen as the new rate.) I first heard this at HI-FI '98 in Los Angeles, where Steven Lee of Canorus, the then distributor of Nagra and dCS, was using a professional dCS 972 sample-rate converter to upsample 44.1kHz audio data, first to 96kHz, then to 192kHz.
