Howdy- You could try SNACK: http://www.speech.kth.se/snack/ Also, I've ported PortAudio to Python on the Mac. PortAudio is allegedly platform-independent, so if you can compile the PortAudio library on your platform (or get binary libraries), you can probably compile my extension. Here's info about PortAudio: http://www.portaudio.com/ Cheers, Tom Loredo
