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 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 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.

- The sampling rate for CD should be larger than 40KHz. - The sampling frequency for audio is higher than the Nyquist rate, as practical filters need to prevent the aliasing to have a finite slope. - The sampling conversion rate is simplified when the rates are multiples of an integer of each other. « Previous Next »

When comparing bitrate, or the amount of data transferred per second, High-Resolution Audio’s bitrate (9,216 kbps) is nearly seven times higher than that of CDs (1,411 kbps) and almost 29 times higher than that of MP3s (320 kbps). And the higher the bitrate, the more accurately the signal is measured.

44.1 kHz (44100 Hz) is the sampling rate of audio CDs giving a 20 kHz maximum frequency. 20 kHz is the highest frequency generally audible by humans, so making 44.1 kHz the logical choice for most audio material.
