Supercollider Study: Randomising RLPF

A simple study in generating sound effects by randomizing the cut-off frequency of RLPF. Put input signal to be something similar to

1{ Splay.ar(Klang.ar(`[[6000,7000,8000,13000,17000],[0.3,0.2,0.2,0.1,0.3]], 1.1, 50)) }

and randomise the cut-off frequency with LFNoise0. In practice the frequencies and their amplitudes in Klang should be the returned value of a list-valued function, so for the x value in LFNoise0.kr(x), but these are implementation details that aren’t important.

The effect is quite OK. The interesting part is after 00:05:30.
