The difference between the original signal and the reconstructed signal is the quantization error and, in this simple quantization scheme, is a deterministic function of the input signal.” The quantization errors that were in the original 24/96 tracks are exacerbated in the down-mix to 16/44.1 audio file that would be used for issuing a CD.
What is "Quantization Error"? - inSync
https://www.sweetwater.com/insync/quantization-error/
For music or program material, the signal is constantly changing and quantization error appears as wideband noise, cleverly referred to as “quantization noise.” It is extremely difficult to measure or spec quantization noise, since it only exists when a signal is present. Quantization error is one reason higher digital resolutions (longer word lengths) and higher …

Quantization Error (Linear Converter) When noise is a result of quantization error, audibility is determined using the signal-to-quantization-noise-ratio... If amplitude values are quantized by rounding to the nearest integer ( the quantizing level) using a …
Digital Audio Chapter Five: Quantitization
https://cmtext.indiana.edu/digital_audio/chapter5_quantize.php
Chapter Five: Digital Audio. 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 …

How DPCM operates is to form the prediction, form an error en by subtracting the prediction from the actual signal, then quantize the error to a quantized version, en. The equations that describe DPCM are as follows: Codewords for quantized error values en are produced using entropy coding, such as Huffman coding.

• To measure the Quantization noise, we should replace the 17 signal bins with the value of the leftmost signal bin (92) to approximate the quantization noise in the signal bins. The integral of this modified PSD from 0 to F s/2 is the noise power, …
