BITCRUSHER

A bitcrusher reduces the sampling rate and resolution of a signal without any filtering, resulting in aliasing and quantization noise. When a digital signal is resampled at a lower sampling rate it creates copies of the signal (aliasing). Unlike a fuzz, these copies are not harmonically related to the original signal. Samplers and digital audio workstations use filters to remove the aliased components, but they are essential to a bitcrusher's character.
