essentially what i'm looking for is a program that will allow me to create sheet music from my wav files (or m4a, aiff, etc.). i use sibelius as my music engraving program, so i could import any midi file into it. i've seen some programs that claim to be able to convert wav to midi (for windows) but i've not seen them for osx. i don't really know how it would be possible, but i figured i'd ask. anyone know of anything? thanks in advance.
