The same algorithm from Audio File Granulator applied to the incoming audio signal.
The bidule that F***s Beyond Repair is a pseudo sample rate/bit depth reducer.
Apply highpass triangular-PDF dithering (adds "ear-friendly" noise to prevent "harsh" quantification noise when downconverting) 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 debth, so when another downconversion 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 juges.
Note2:Make sure the incoming signals DONT break the [-1;1] limit.
