Newbis: I'm seeing "s" in a lot of the plugins. I'm guessing "s" is what allows the code to refer to the existing sound that's being modified? The "s" variable is the sound object given from the Audacity Nyquist interface to the Nyquist interpreter, see Nyquist Variables . Unfortunately the Audacit...

Sorry, not mucht time yet, but maybe this helps: The Nyquist FMOSC can take a wavetable as argument. If you turn the Audacity "s" sound into a wavetable (or two wavetables with a stereo sound) then FMOSC can do an LFO-controlled frequency modulation (= vibrato) with it. If a second FMOSC is used as ...

celoftis: ... do you have any suggestions on how to approach this task?

See http://sox.sourceforge.net/, i.e. libsox, also the sox "-m" option and the "mixer" effect.

I'm sorry to tell but I think here is a general misunderstanding what Nyquist in Audacity can do and what not. Nyquist has no access to the Audacity GUI, so there is no way to pop up a "Dialog Box 2" or to highlight parts of the waveform with Nyquist in Audacity. If you choose a Nyquist Plugin, then...

Jvo: Imagine you display a stereo signal on an oscilloscope in x-y mode ... if there is just one signal in one channel the display shows a simple line ... if you insert the elliptical equalizer into the signal path the picture changes to an ellipse due to the phase shifts introduced. Thanks, that's...

Here is what happens if Germans try to use English language: Preface: Somewhere in the early 2000s the German commercials department of a famous fashion manufacturer (no names here) came in a fit of "everything today sells much better with an english name" to the not really well-thought idea to offe...

steve: I don't think that *scratch* can hold sounds can it? Obama says: yes, we can! ;; store a sound in *scratch* (let ((len (round len))) (setq *scratch* (snd-fetch-array s len len))) ;; read a sound from *scratch* (snd-from-array 0.0 *sound-srate* *scratch*) A Nyquist "sound" object is a pointer...

Everything looks as if Steve is right and you just simply can't do this with Nyquist in Audacity. Mixing the tracks via *scratch* and then finding the peak afterwards would be the only other way to get the desired result, but this will surely crash Audacity if the tracks are longer than a few seconds.

You could store the (peak s) value in *scratch* and then compare it to the (peak s) value of all subsequent tracks but I'm afraid that Audacity then will start to allocate memory for all tracks together and crash, but haven't tested this yet.
