Digital Audio Chapter Five: Quantitization
https://cmtext.indiana.edu/digital_audio/chapter5_quantize.php
6. Quantizing, Approximation Errors and Sample Size. Samples, the periodic snapshots of the instantaneous amplitude of an input signal taken by the ADC, are assigned numeric values that the computer or digital circuit can use in a process called quantization.The number of available values which can be assigned is determined by the number of bits (0's and 1's) used for each …

Chapter 2 Quantization. Basic operations for AD conversion of a continuous-time signal x(t) are the sampling and quantization of x(n) yielding the quantized sequence x Q (n) (see Fig. 2.1).Before discussing AD/DA conversion techniques and the choice of the sampling frequency f S = 1/T S in Chapter 3 we will introduce the quantization of the samples x(n) with finite number …

For speech, we could modify quantization steps as we go, by estimating the mean and variance of a patch of signal values and shifting quantization steps accordingly, for every block of signal values. That is, starting at time i we could take a block of N values fn and try to minimize the quantization error:

Quantization is the process of converting a continuous analog audio signal to a digital signal with discrete numerical values. Example: In a compact disc, an analog recording is converted to a digital signal sampled at 44,100Hz and quantized with 16-bits of data per sample.

Signals - Quantization and Sampling
https://makeabilitylab.github.io/physcomp/signals/QuantizationAndSampling/index.html
1. Quantization and sampling. ¶. Most signals in life are continuous: pressure waves propogating through air, chemical reactions, body movement. For computers to process these continuous signals, however, they must be converted to digital representations via a Analog-to-Digital Converter (ADC). A digital signal is different from its continous ...
