generating f(x) type wave forms?

Permanent link to this post Posted by dmonty » Thu Mar 16, 2017 1:57 pm

How can I generate various y=f(x) wave forms using nyquist/audacity?

I'd like to work with this:
https://www.wolframalpha.com/input/?i=plot+x%5E3+*+e%5E(sin+(+x+*+3))+*+0.00001,+x%3D0+to+33

Thanks.

There's an example in my most recent reply to your other topic: viewtopic.php?p=324116#p324116
This example generates a pulse derived from: y = c^-(x^2)

In brief, create an array to hold the 'y' values, and populate the array, mapping the array index values to 'x' values. Then use the "snd-from-array" function to translate the array into a sound (http://www.audacity-forum.de/download/e ... l#index158)

Goldwave audio-editor has a function-generator which does that sort of thing ....

I thought this sounded interesting, so I've written a little plug-in here: viewtopic.php?p=324316#p324316
