Digital Audio Chapter Five: Quantitization
https://cmtext.indiana.edu/digital_audio/chapter5_quantize.php
The solution to reducing digital noise is to use larger sample word sizes (greater bit depth or precision), which therefore corresponds to the dynamic range of the system, since it affects the signal-to-noise ratio. For digital PCM systems, this is …

https://cmtext.indiana.edu/digital_audio/chapter5_quantize2.php
Chapter Five: Digital Audio. 6. Quantizing, Approximation Errors and Sample Size | Page 2. Digital audio editing programs can often use sample sizes above their final product's bit depth. Standard samples sizes of 20-bits, 24-bits, even 32-bit floating-point or long integer samples are now common, used to minimize fractional values and their ...
Detection of quantization distortion in digital audio systems

In recent digital audio systems, 16‐bit uniform quantization is employed in most cases, because a dynamic range of 96 dB is considered satisfactory for most cases. Ideally speaking, a dynamic range of more than 120 dB is required in music reproduction.

Quantization Level - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/engineering/quantization-level
One audio wave will occupy the time of 50 radio waves, which means in effect that the shape of the audio wave is represented by the amplitudes of the peaks of 50 radio waves, a 50-level quantization. You might also like to consider what sort of quantization is involved when an analog tape system uses a bias frequency of only 110 kHz, as many do.

μ-Law. μ law is a compression algorithm used for non-uniform quantization. The expression of μ law is. y = (ln (1 + μ (m/mp)))/ (ln (1 + μ)) Where μ is the compression parameter and m is the input amplitude & mp is the peak amplitude of the input signal. When μ=0, then there is no compression and the quantization becomes uniform.

Chapter 5 Sampling and Quantization Often the domain and the range of an original signal x(t) are modeled as contin- uous. That is, the time (or spatial) coordinate t is allowed to take on arbitrary real values (perhaps over some interval) and the value x(t) of the signal itself is allowed to take on arbitrary real values (again perhaps within some interval).
