AUDIO CODING: BASICS AND STATE OF THE AR T
http://www.eeng.dcu.ie/~ee502/AudioCodingBasics.pdf
The basic task of a perceptual audio coding system is to compress the digital audio data in a way that - the compression is as efficient as possible, i.e. the compressed file is as small as possible and - the reconstructed (decoded) audio sounds exactly (or as close as possible) to the original audio before compression.

8 bits (256 levels) linear encoding would probably be enough if the signal always used the full range. But signal varies in loudness. If full range is used for loud parts, quiet parts will suffer from bad quantization noise (only a few levels used). If full range is used for quiet parts, loud parts will clip, resulting in really bad noise.

The basic principles behind the quantization, time to frequency mapping and psychoacoustic models stages of an audio coding system are analyzed. Emerging audio formats and new trends, such as parametric audio coding, perceptual noise substitution, PNS, spectral band replication, SBR, and sinusoidal modelling are examined.

Audio Coding (cont.) In general, producing quantized sampled output for audio is called PCM (Pulse Code Modulation). The differences version is called DPCM (and a crude but efficient variant is called DM). The adaptive version is called ADPCM.
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!
