Building representational models of that process is hard. So most people don't bother - they mush stuff up at random and keep the bits they like.
Like this.
Unfortunately this music prof is ignoring 60-odd years of computer music history and reinventing the glitch-with-Max thing that was big 10-15 years ago.
Autechre, Amon Tobin, and many many others have been making music like this for a while now. The sound/sample world is different, but the techniques are very similar.
Why no, American born electronic artist Brian Transeau "developed" the technique as recently as 2011.
If this guy created anything, it's the plugin with the same name that automates the process (and even that is debetable for 2011 -- similar plugin tools existed way before).
In essense: don't trust anything your read on the internet. This Wikipedia page is an example of the worst BS on Wikipedia, it should be taken down.
Now I wonder how that Wikipedia article survives...
Lejaren Hiller showed that computers can compose competent music in 1957 with the Illiac Suite. Since then there have been countless other using computers doing things like the project in this article (Autechre is a PERFECT example).
I love that people are doing work like this and sharing it (full disclosure, this is a hobby of mine), but I wish it were presented in a less pretentious way (although admittedly this comment could probably also be a lot less pretentious).
