    A higher sample rate will give you a more precise capture of the original audio signal. In a typical digital audio CD recording, the sampling rate is …

Understanding audio bitrate and audio quality | Adobe

    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.

    Sample rate directly affects audio fidelity in terms of upper frequency response: the higher the sample rate, the higher the available frequency response. A fundamental principle of sampling states that to accurately capture a sound, the sample rate must be at least twice the highest frequency in the sound.

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 audio sample rate determines the range of frequencies captured in digital audio. In most DAWs, you’ll find an adjustable sample rate in your audio preferences. This controls the sample rate for audio in your project. The options you see in the average DAW—44.1 kHz, 48 kHz—may seem a bit random, but they aren’t!

Sound Quality vs. Data Rate

    https://www.dspguide.com/ch22/3.htm
    An 8 kHz sampling rate, with an ADC precision of 8 bits per sample, results in a data rate of 64k bits/sec. This is the brute force data rate for natural sounding speech. Notice that speech requires less than 10% of the data rate of high fidelity music.

Codec comparisons by bitrate, CPU usage, sample rate, and ...

    Best (20+ kbit/s) Good. Fair. Poor. * Numbers listed represent the default bitrate for each codec. Represents one voice stream at theoretical max. Codec bitrates are only in effect while speech is active (either being transmitted or received). These exclude 14.4 kbit/s of overhead from Vivox packet headers while speech is active. ** PCMU is essentially free in terms of CPU usage.
