// title: arbitrary nonlinear filter
// author: mesmeon
// description:
// run first code block, then second, then third. re-run third block to randomly generate a new array of filter parameters. processes standard audio in and plays through standard audio out
// code:
//larger sparse arrays; some may lead to silence
//feedback warning!
