Big difference would be stochastic grain selection (with
inputs/control over the selection tendencies), but it'd definitely
start as a straight-up windowed fft convolution engine. E.g. one
parameter that could make for interesting selections is to hunt for
decaying peaks, and favor using those to get a "crisper output"
instead of the haze that results from windowed fft convolution.
