One of the things I do frequently, either for the sake of experimentation or for inspiration, is to apply multiple levels of processing with the intent of significantly manipulating an otherwise mundane sound. With a myriad of audio effects available to us this is also a good exercise in learning how certain kinds of processing impacts audio.
I started with a loop of hand drums going through Fragulator (Pluggo). Fragulator fragments the input signal into chunks, similar to grain-table synthesis. The chunks are looped at varying speeds to create a broad variety of effects. It was already drastically different from the original, so I chose to add only one more device. Harmonic Filter (Pluggo again) controls twenty-five filters with a cellular automata algorithm. I used its filter sweep mechanism to spread the stereo spectrum and provide tonal variety over the 1:25 minute recording.
