Randomized Splicing

Hello everyone, I am working on a linguistics study in which I am taking speech samples, chopping them, and randomly splicing them back together in order to make the speech unintelligible. I got this great chopper code from this topic thread http://forum.audacityteam.org/viewtopic ... 19#p233319 and I thought I would put it out and ask is any one knows a way to randomize chunks of audio. I have thought about splitting the audio track around the chopped chunks and then manually moving them around, but perhaps there is an easier way. Thanks for any insight :)

Was the "reverso" effect not suitable? http://forum.audacityteam.org/viewtopic ... 46#p258146

Does this have anything to do with recording inter-dimensional beings?

We ended up going with the chopper code you suggested- which was super helpful! Now I'm trying to figure out a way to assemble the chopped bits back in random order :)

I found this old (experimental) plugin and have updated it and enabled it for longer audio chunks than the original design. Give this a go (try the default settings first):
wavelet.ny
(3.16 KiB) Downloaded 185 times
It is called "Wavelet..." (which is a reference to early experiments by Iannis Xenakis rather than to modern Wavelet theory).
Note that this plugin is only intended for experimental purposes - there is no error checking in the code, so if you do something stupid with it, it will do something stupid ;)
If you use it in your research and your research culminates in a published paper, please include a credit (and I'd be interested to read the final paper, if that could be arranged).
