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.
