I don't think Apple provides a function to do this in Mac OS X.
This is one of heavy subjects in DSP field.
If you want to detect the frequency of one tone,
it can be easily done with FFT.
But it's not that easy if you don't know what FFT result data mean
and how to fetch the fundamental frequency of the tone from the data.
If the sound is complex, for example two tones at the same time,
it becomes much much harder to detect the frequencies.
