Bonjour. J'utilise Audacity 2.0.3/ Mon ordinateur fonctionne sous Windows height. Je n'ai pas de carte-son externe. Je voudrais enregistrer la sortie audio d'un software dans Audacity. Le problème est que jusqu'à présent , lorsque j'enregistrais, c'était le micro de mon portable qui captais la sorti...

Bonjour. J'utilise depuis peu un software gratuit où l'on peut charger des fichiers au format Wave. J'avais essayé d'encoder des fichiers audio dans ce format avec Audacity 2.0.3/ mais je me suis rendu compte, en regardant les propriétés de ces fichiers, que la vitesse de transmission devait être ég...

I thank you. I do not understant how this code works. If the sign = means: something is equal to the sum of x more y, It would mean that "modstep" here is equal to the sum of x more y. It is just if I say that x is equal in:(hz-to-step and y is equal in: (* (3.0 5.0) (step-to-hz C4)) or (* (0.6 step...

Hello Sir. I looked for a function in LISP who would look like in: two things are identical (in fact, they are not identical). I found only (eql [" (eql expr1 expr2) [LISP] - are the expressions identical? (works with all numbers)]. When I pass of a code written in Sal, in a code written in LISP, I ...

Hello Sirs. I work on the following code: set modstep = hz-to-step((3.0 / 5.0) * step-to-hz(c4)) play fmosc(c4, pwl(1, 4000, 1) * osc(modstep)) ~ 10 This code generates a wave where appears a harmonic scanning. I wrote:  (setq modstep (eql (hz-to-step (/ 3.0 5.0)) (step-to-hz C4) )) (defun mytone ()...

Hello sir.
It seems to me that fmosc has 3 arguments: (step-to-hz pitch), vibamp and lfo. The pitch has for value E4 or 64. Vibamp has for value 0.01. lfo has for value 6;

I thank you. In fact, why I try to make understand to Nyquist which is the ratio, it is because the code which I wrote does not still work. i wrote: (setq vibamp 0.01) (setq lfo 6) (defun vibtone (pitch vibamp) (mult (fmosc (step-to-hz pitch) vibamp lfo) (*saw-table*))) (vibtone E4 5) The Nyquist pr...

Hello sir. I moved forward in the understanding of the variable vibamp. This variable corresponds to the amplitude of the vibrato. The amplitude is expressed as a ratio of the frequency of the fundamental of the sound. If vibamp is equal to 1, the frequency of the fundamental oscillates between -50 ...

I thank the moderators for their comments. If I do not call the vibtone function it is maybe because I did not specify the role of vibamp. I would want that Nyquist understands that if I write (vibamp 0.01) it wants to say: vibamp is a variable and 0.01 is a value chosen for vibamp. But also, it mea...

I thank steve for these comments. I thus corrected a part of the code in LISP. I wrote: (setq vibamp 0.01)(setq pitch 76) (defun vibtone (pitch vibamp) (fmosc pitch (* (step-to-hz pitch vibamp) (lfo 6 10 *saw-table*) ))) It allows to associate two arguments (76 and 0.01) with the function step-to-hz...
