Music Training Question

[blackcougar]

is there any way to work out what note is played through the speaker input, maybe a c++ library or something.

The idea is that one could play a piece of music (piano/guitar/flute etc) into a speaker from notation on the screen and then get an assessment of how well they played the piece.

You could even make it an educational game!

Any comments?
