I'm a full-time python/zope hacker but never done any multimedia apps with python. but here's some libs you might look at: Numeric (c extensions that give you high-speed matrix math stuff, might be handy for DSP) http://www.pfdubois.com/numpy/ SciPi - extensions that give you lots of pretty fast stuff including data visualization and DSP. http://www.scipy.org pygame - libraries for doing games and apps with openGL graphics, includes a lot of handy multimedia stuff (e.g. an audio mixer). http://www.pygame.org pyUI - built on pygame, for general-purpose UIs. http://pyui.sourceforge.net/ -- Paul Winkler http://www.slinkp.com
