Apps Reproducing sound from freq. spectrum

Dear readers,

I'd already like to thank you for your time.


We (Me and 3 other students) are working on an application for android.
School said: "create an application android that has to do something to do with sound. Sound has to be the key-factor of the application.".

So what we are creating is a soundboard. It reproduces the sound from the parameters we insert.

So let's say you have a piano. with (random):
harmonic frequency 1: 200Hz
harmonic frequency 2: 400Hz
harmonic frequency 3: 600Hz
harmon... etc.

So what I want to do is reproduce a sound throughout the speakers/headphone of the android based telephone (HTC).

Does anyone have tutorial or name of a class we can use?

Anything that can be useful, please tell us about. We've read the whole google database, but nothing useful (we think) can be found.

I hope that you guys have some information for us.


Greats,

Jelmer (and the rest of my project group)
