Cool, Nathan. I was thinking about writing a singing game - well maybe not a game so much as a tool. It plays scales and gives you your statistical accuracy as far as hitting the correct note (just based on pitch - also would do intervals etc.) I was thinking about also adding support for music so you could practice hitting notes for a specific song - maybe encoded as a MIDI track so you could just load up a midi file and choose a specific track to be the vocal line and the rest will just play as a midi file for accompaniment. That's all extra, though. The scales stuff is the most important. I have been trying to decide if processing the wav to get frequency information in Python would be fast enough or not -- I'll probably try it first and see. Do you have any opinions on the relative speed of this? Would I have to leverage numeric or some fft library in order to get realtime performance? Because at that point I may just write it in C and make a socket-based reporting system that lets you query current pitch, and just request that information from Python. That also has the benefit that you could set the processing C code affinity to a different processor core from your Python frontend.
Is your API stable at this point?
