The Sonic Reducer is a simple bitcruser/aliaser that uses sample and hold to degrade the signal. It's loosely based on the Analog Bitcrusher by Colin Raffel, but improved in many ways.
Stripboard layout and PCB etch file (both verified)
Resolution - controls the pulse width of the oscillator. Narrower pulses lets more clean signal through, so it works like a clean blend
Sample Rate - controls the frequency of the oscillator
