Attached please find a screenshot--though the mailing list may not let it through--of some of the sound analysis available in rsound.plt, a planet package that I'm developing and using with my class. It is emphatically not real-time at the moment, and would therefore be more of a starting point for your game than anything else, but you might be interested; this picture shows a piano waveform, a zoomed version of the same, and a picture of the evolution of the FFT over time.
