Given that you are manipulating multiple wav files and joining them 
together into a swf file, I can't believe that you seriously believe 
that the Python code is likely to be the bottleneck. If it takes ten 
seconds to process the wav files into a swf file, who cares if you 
speed the Python code up from 0.02 seconds to 0.01 seconds?

But I could be wrong... I look forward to seeing the profiling results 
from your code.
