jitter — Generates a segmented line whose segments are randomly generated.
kamp -- Amplitude of jitter deviation
kcpsMin -- Minimum speed of random frequency variations (expressed in cps)
kcpsMax -- Maximum speed of random frequency variations (expressed in cps)
jitter generates a segmented line whose segments are randomly generated inside the +kamp and -kamp interval. Duration of each segment is a random value generated according to kcpsmin and kcpsmax values.
jitter can be used to make more natural and “analog-sounding” some static, dull sound. For best results, it is suggested to keep its amplitude moderate.
Here is an example of the jitter opcode. It uses the file jitter.csd.
