Quantization Grid, Split from Topic ID #55966 Options

[KMD]

I have thought that this phenomana may be real for years . I call it the "quantiztion grid". An analog waveform can change direction or cross the zero line at an infinite number of locations. Sampling and Quantization create a grid to which features of the waveform are statistically constrained. Increasing the sample rate at a fixed bandwidth inreases the quantization grid density. Whether it is perceivable is what is in question. This experiment may have proved it. I will give some thought to a simillar experiment that forum members can do for themselves and start a new topic on it.

The movement of the quantization levels by dithering averages to zero over a number of points. Statistically the dithered quantization levels still fall on the original quantization points plus a deviation ether side with the statistical distribution shape determined by the noise used. I think it would be useful to be able to statistically analyse the shape of a piece of audio to asertain what process recorded it.
