Well, Nicholas Chase just posted an OpenLaszlo tutorial/app that shows how OpenLaszlo handles sounds. Try http://www-128.ibm.com/developerworks/edu/os-dw-os-php-openlaszlo1-i.html You have to register, but it's free, and they don't bug you. It's PHP driven, but that part's easily ported to Python.
Anyway, there's the basis of an all open-source or freeware application that animates with sounds. Ron -- http://mail.python.org/mailman/listinfo/python-list
