hi thomas,
I know that python is actually too slow for audio processing,
but I just want to do a fft, extract critical bands and some other analysis 
- feature extraction in general. all that can be done using Numeric Python 
is a highly optimized package for number crunching tasks. that package is 
written in c and I wouldn't
get it much faster if I wrote an external in c than just using numpy.
I've already checked if I could do all analysis using pd-objects and just 
passing the results to pyext but it doesn't seem to be possible, at least 
not as flexible as I'd need it.
I've heard about "dyn" and the things that should get possible with it, but 
it doesn't help me for what i want to do.
and supercollider is only for mac.
if i'd just get chunks of audio into pyext it would be fine...
