is there a way I can take a sound and multiply the waveform by another sounds waveform using the mult command?
The easiest way is to create a stereo track with one sound in the left channel and the other sound in the right channel.
To join two mono tracks to create one stereo track, see: http://manual.audacityteam.org/man/splitting_and_joining_stereo_tracks.html
You can then multiply the sound in the left channel with the sound in the right channel, and return the result to both channels:
(mult (aref *track* 0)(aref *track* 1))
That will amplitude modulate one channel with the other, the result probably won’t be pleasant/musical …
I just started to use audacity and I would like to multiply a soundtrack by its self.
so what I did so far was duplicating the sound (named one sound1 and the other sound2)
And put that in Nyquist Prompt:
(mult sound1 sound2)
what did I do wrong and should I use it as a stereo sound?
I am sorry I have no glance about anything
Thanks for your help!
In the Nyquist Prompt, you can do this (assuming a mono track):
(mult *track* *track*)
TRACK is a special symbol that passes the selected audio to Nyquist. If the selection is a mono track, then TRACK is a sound. If a stereo track is selected, then TRACK is an array of sounds, with the left channel as the first element of the array, and the right channel as the second element.
