For more info about SC \, visit www.audiosynth.com. +Anyways...SC has a unit generator called "DUST". Dust will produce +random impulses at a specified "density". I believe that Dust was given +its name because it creates a sound that is similar to actual dust +on old vinyl LP's -- you know that old crackling sound like Rice Krispies. +; +#X text 432 331 The idea is quite simple. If you want a "very dusty" +sound \, you make the density quite high...if you want a "slightly +dusty" sound \, you make the density quite low.; +#X obj 434 484 delay; +#X obj 434 506 bng 15 50 10 0 empty empty empty 0 -6 0 8 -262144 -1 +-1; +#X obj 434 423 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 +1; +#X text 432 376 Dust.ar(2) in SC will produce 2 dusty impulses randomly +per second.
