None of the above is suitable for signal processing in Python, for (1)

I would use the 'array' type in the stdlib or better still, the array
type in the NumPy package. The NumPy array has a much richer set of
operators you can apply efficiently to a signal sample stream.
Years ago I used it on a contract for on-the-fly 2-D image processing
from a batch currency scanner (counterfeit detection) and it was able to
do pretty complicated calculations and keep up.

True, numpy rocks :), I've used it for speech processing myself with
audiolab that Asokan mentioned and now i'm using it for 2d biomedical
image processing ... Although I know nothing about GNUradio, I can tell
you numpy rocks... :D
