Interesting. Thanks Dave, Greg and Alex.

I looked at PySonic, but it uses a closed source library, so that rules 
it out.

PythonSound looks like an interesting project. It is a pretty-much 
complete synthetic music composition system. Very neat. I'm not sure how 
current it is though. Doesn't look like much has happened since 2002. 
Still, if it works that is enough.

I have played with snack. It provides a very simple way for python to 
use, play, and filter sounds as well as generating tones. It can also 
convert formats on-the-fly. And it lets you view sounds graphically 
(waveform, spectrogram, energy section), which can be useful for some 
things I want to do in the future.

OpenAL has some interesting 3D capabilities -- something that will be 
very useful for me later... but after a quick scan thru the 
documentation I can't see much else. Guess I have to sit down and really 
delve into the docs.

MusicKit (& SndKit) looks very interesting, for building music, sound, 
signal processing & MIDI applications. I haven't had time to investigate 
it properly yet.

Also, of course, python itself has a very basic wave module with simple 
capabilities.

Best wishes,

- Miriam
