Hallo,
Does anybody know how I get a delayline with fast changes in delay length? The
delay length should be gaussian normal distributed. I always get noise and
clips in audio signal.
sr = 44100
ksmps = 100
nchnls = 2
0dbfs = 1.0
instr 1
; kRes random 0, 44.1
kRes gauss 1 * 0.01
; kres =10
kAmp = 0.5 ; amplitude
kCps = 1 ; frequency of output (1 if unknown)
iFn = 1
iBas = 1 ; frequency of input
iMod = 1 ; play as loop
gaOutSum init 0
aDump delayr 1
aAudioIn loscil kAmp, kCps, iFn, iBas, iMod
aMove deltapi abs(kRes)
delayw aAudioIn
out aAudioIn , aMove
; printk 0.1, kresdeltapi
; printk 0.1, round(abs(kres))
endin
f 1 0 0 1 "guitar_sample_1.wav" 0 0 0

What do you expect to hear?
I'm not sure exactly what you're trying to do, but when I try your code I hear pretty much what I'd expect to... 'modulated white noise' on the delayed channel. (I don't have your guitar sample, but I used 'sing.wav' -- from the examples, I think.) After all, Gaussian noise is still a string of random numbers, so each successive sample (or rather sample buffer, size depending on that a/k ratio) will be picked off a random point in the delay line, and will be pretty independent of the previous one -- hence, noise... (:-))
I suspect what you're looking for is some kind of randomized 'sweep' in the delay. My mind is blank though on how you might go about generating that.
