Hello Matthew,

For this application I would strongly consider using a system designed and optimised for real-time DSP.

SuperCollider would be my first choice: http://supercollider.sourceforge.net/


My kind regards,
J Anderson

The problem I'm having is that I can't find anyway to filter specific frequencies from a live microphone input. I've found a number of python libraries that seem able to achieve just that but they any examples I find are for far more complicated things. SciPi is the only one with a decent following that could possibly help me. So, to reiterate, I wanted to know how I could choose an audio port and look for a specific frequency being picked up on that port. (I'm using Ubuntu, Python 2.7.1, and the latest version of Numpy + Scipy)
