Interestingly, he’s also included the ability to downsample audio, giving is project both pure digital effects for the price of one. created his bitcrusher purely in software, sending the resulting bitcrushed and much smaller file to an Arduino for playback. It sounds like a robotic nightmare, but it’s still there. Play it through a speaker at a decent sample rate, and you can still hear it. Instead of recording samples of 256 values for 8-bit audio or ~65000 values for 16-bit audio, a one-bit bitcrusher only records one value – on or off. Because and say we can only reproduce audio signals less than half of the sample rate if you run some audio through a sample rate reducer set to 1kHz, it’ll sound like crap, but you’ll also only get bass. There are two major effects that are purely in the digital domain.
wanted to experiment with bitcrushing, and couldn’t find what he wanted. One of those is the bit crusher, an effect that turns 8- or 16-bit audio into mush.
Compared to the traditional way of doing things, digital audio is relatively new, and there is still untapped potential for new processes and effects. When it comes to audio effects, you have your delay, reverb, chorus, phasing, and the rest that were derived from strictly analog processes.
