Audacity Forum

Hello sirs. I thank Steve. I thus wrote the part of the code which corresponds in (* a b c). a = the function (here, I believe that it is (step-to-hz pitch) and two arguments: b = vibamp and c = 0.01 I wrote: (fmosc pitch(*(step-to-hz pitch) vibamp 0.01) (lfo 6 *saw-table*))) The problem also, is th...

Hello sirs. I thank steve for these comments. I have an other code noted in Sal. define function vibtone(pitch, vibamp) return fmosc(pitch, step-to-hz(pitch) * vibamp * 0.01 * lfo(6), *saw-table*) play vibtone(e5, 5) The author of the code indicates: ;; making vibrato a percentage of the fundamental...

I thank Steve for these very precise comments. I have 3 questions to ask. 1) The code SAL is preceded by the following text:"...The C:M ratio is based on frequencies, so we convert pitch p to Hz using step-to-hz..." My question is the following one: is it the code according to whom realizes this cal...

Hello sir.
I would want to use this code in the Nyquist Prompt in Audacity.

Hello Sirs. I try to write in LISP this code noted in Sal: define function fm(p, a, c-m, mod-ratio) return a * fmosc(p, mod-ratio * step-to-hz(p) * hzosc(step-to-hz(p) * recip(c-m))) play fm(gs2, pwl(0.3, 1, 0.7, 1, 1), 0.5, pwlv(0.5, 0.5, 10, 1, 2)) ~ 2 return s I wrote: (defun fm (p a c-m mod-rati...

Hello. I thank Steve for its help. I try to use in the console Nyquist of Audacity 2.03 the code following SAL: define function fm-lfo(amp, freq) return sound-srate-abs(*default-control-srate*, amp * hzosc(freq)) play fmosc(g5, fm-lfo(pwl(1, 500), 6)) ~ 2 I wrote: (setf amp 1 ) (setf freq 440) (defu...

Hello Sirs. Somebody could indicate to me how we write in lisp langage this code:
define function fm-lfo(amp, freq)
return sound-srate-abs(*default-control-srate*,
amp * hzosc(freq))
Beforehand thank you.

I found this code . it generates glissandi. On the other hand, it is very difficult to have a control of this code. I simplified It. I would want to ask beginner's question. The code is the following one: (defmacro sweep (dur) (stretch-abs 1 (mult (pwl 0 0.8 dur 0.05 dur) (hzosc (sum 440 (mult 3360 ...

Hello Sirs. I found this code on the forum. it generates glissandis. On the other hand, it is very difficult to have a control of this code. The code is the following one: (defmacro sweep (dur) `(stretch-abs 1 (mult (pwl 0 0.8 dur 0.05 dur) (hzosc (sum 440 (mult 3360 (ramp dur))))))) (defun lowpass ...

Hello Sirs. I thank Steve for his comment. If I had noted the value " 12 "it was because I believed that this value would be the duration in seconds of the sound affected by a random pan. After all, I try to generate a sound at the end of 35 seconds. I would like that this sound lasts 12 seconds. It...
