A bit cruncher is not a  established descritpion as "oscillator" or 
"filter" would be.


Usually in the audio context it means a function, that converts digital 
(audio) signals by non audio related, but more logical means.

Example:
A filter reduces partial tones of a signal. This is something, which 
might happen also with natural musical instruments (e.g a damper on a 
violins string)


A simple bit crunching for example can reduce the resolution of a 
digital signal  from 16 Bit to 8 bit; this has nothing to do with a 
musical context and is a plain technical approach, though it hass a kind 
of musical effect (adding overtonal noise to the signal).
Similar the reuction of sampling rate.


An advanced kind of bitcrunching is the exchange of bits in their 
position corrsponding to a certain pattern.

Lets assume a pattern like "move each bit three positions forward round 
robbing".  A byte like 00010000 (which is the decimal value 16) wil 
become 010000000 (which is decimal 128). But a byte like 10111101 (which 
is decimal 188) is converted to 11110110 (which is decimal 246). So the 
same function creates with the first value a change of 112 with the 
second value a change of 58. So the result of this "crunching" is 
nothing which has to do with simple natural processes which could be 
described in "simple" algebra. The results do not sound like a natural 
change.

In fact. most of the advanced "crunching" patterns sound with audio like 
ugly distortion or noise , but in some way a controllable noise; but 
applied to slower changing controlvoltages this crunching might result 
in interesting CV-changes.
