If you explore it carefully, you can gain some pretty cool insights.

Fibonacci sequence might be a good one to experiment with at the start, just to get a feel for how things work.

Also you can upload your own sound files for calculation of "auditory roughness", of frequency analysis, etc."

and it's all done through a web interface.

I expect I'll like this.

woah listen to pi @ high tempo.

use a high enough value for precision so the tune lasts long enough.

This is a great way to "visualize" mathematical patterns.

Except it's auditory visualization.

I guess that'd be 'auditorialization'

also helps to constrain the pitch span to something tighter than 0-88 - so maybe 20-60 - that way the melodies are brought into sharper focus
