I was doing a little performance comparison test with Supercollider and I found this interesting:
{
Mix.new(
Array.fill(300,
{ Pan2.ar(SinOsc.ar(LFNoise0.kr(rrand(0,20)).range(40, 110).midicps),
LFNoise1.kr(0.2),
300.reciprocal) }) )
}.play;
It sounded to me like the background noise people make while talking and talking in those big shopping centers, but it has many artifacts in the foreground. Anyhow, the background noise sounds similar to me. Eh…
