Note/Frequency Calculator

[Adagio12]

Hey Folks

Can any of you Fine Feathered Philanthropic Bitheads point me in the direction of a piece of software which will,when given an alternate frequency other than A-440Hz as concert pitch,give a readout of the new "adjusted" frequencies of all the other MIDI note numbers... preferably for macosx...or otherwise for PC

Cheers!

Make your own:

f = f0 * 2^((n - 57) / 12)

where n is the MIDI note number (57 = middle A), ^ denotes the power operation, f0 is the frequency of middle A (e.g., 440 Hz), and f is the frequency of the note you want.

Of course, this only works for equal temperaments.
