Download MFreeEffectsBundle from Meldaproductions and use MAnalyzer. This is hands down the best in the world at this and other stuff as well. The guy seems to be some sort of genius or something. It's borderline disgusting. :hihi:

The last two formulas under the heading "Note frequency (hertz)" is what you want.

middle A is generally 440hz isn't it? so an octave above that
would be 880hz.(?eeek..). you must be able to find a chart for
this. middle A, being MIDI note#..?
