Hi,

I'm looking for some way to generate a tone that resembles the sound of an instrument. I need precise control of the base frequency (pitch). I'm wondering what would be the best way to generate it on an iPhone. Store a file with a know frequency and resample it to the desired frequency? Synthesize a tone by calculating a bunch of sines? Doing some FFT trick on a file? If someone can give some insight into what would best fit the H/W available it would be grateful.

Kind regards,

Remco Poelstra
