The same algorithm from Audio File Granulator applied to the incoming (and buffered) audio signal
The bidule that F***s Beyond Repair is a pseudo sample rate/bit depth reducer.
Apply high-pass triangular-PDF dithering (adds "ear-friendly" noise to prevent "harsh" quantification noise when down-converting) on an audio signal. The 32 bit floating point outputs samples coming out of this bidule will only contain the resolution of your chosen final bit depth, so when another down-conversion is made in the audio outputs OR the audio file outputs, then nothing more will be taken out.
Note1: This module possibly does a better job at dithering than the Dither option in the DSP preferences, but as dithering is to a large extent a suggestive improvement, we let you be the judges.
Note2:Make sure the incoming signal DO NOT break the [-1;1] limit.
