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 frequencies between 20 Hz and 20 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 bit depth may be 16-bit, 24-bit, 32-bit, for audio CD 16-bit is preferred. The sample rate is measured in hertz(Hz). According to Nyquist Sampling theorem the sampling frequency to produce the exact original waveform should be double the original frequency of the signal. The human hearing bandwidth is 20Hz-20kHz, the audio sampled can be at the rate …

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.

Sound Quality Comparison of Hi-Res Audio vs. CD vs. …

    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.

    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. If you’re wondering why the frequency is so high when the human ear can only hear frequencies up to 20kHz at best.

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.
