Digital Audio Basics: Audio Sample Rate and Bit Depth

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 …

The sampling rate of 44.1 kHz came to be that of the Compact Disc. Even though CD has no video circuitry, the equipment used to make CD masters was originally video based and determined the sampling rate. This sounds good, except that NTSC video actually runs at 29.97 frames per second, which makes the field rate come out to 59.94 instead of 60.
Explanation of 44.1 kHz CD sampling rate - Columbia University

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.

A higher sample rate tends to deliver a better-quality audio reproduction. Sample rates are usually measured per second, using kilohertz (kHz) or cycles per second. CDs are usually recorded at 44.1kHz – which means that every second, 44,100 samples were taken. If you can master sample rates, you can create more accurate recordings.

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.

In a typical digital audio CD recording, the sampling rate is 44,100 or 44.1kHz. If you’re wondering why the frequency is so high when the human ear can only hear frequencies up to 20kHz at best. It’s because of the Nyquist-Shannon sampling theorem. Christopher D’Ambrose puts the hearing ability of the normal middle-aged adult at 12-14 kHz).

High-Resolution Audio files have a sampling frequency of 96 kHz/24 bit, which is significantly higher than the 44.1 KHz/16 bit sampling frequency of CDs. How does that translate to the listening experience? Listening to High-Resolution Audio allows you to pick up on the subtle details and nuances that you would hear in a recording studio.

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.
