Hi!

You may find this example useful:

http://neuralensemble.org/trac/NeuroTools/browser/trunk/examples/single_neuron/playing_with_simple_single_neuron.py

We used scikits.audiolab to record a numpy array and pyaudio to play  
it on your computer.

(and btw, it's an educational example, not scientific!)

cheers
