Iphone FFT implementation

It's required to have 2 deliverables:

- an Objective C Iphone application embeddable library

- a sample AppStore distributable application

capable of:

- listening to an input sound from the mic/line-in in a pre defined bandwidth interval (e.g. music instruments)

- provide a quasi real time measurement (customizable sampling time) for the sound frequency

(e.g. providing a Fast Fourier Transform implementation)

- output the value of the frequency on screen

There are no graphical requirements, the library should be as portable as possible and the sample application as thin as possible.

Hi, i can prepare a really simple iPhone app (using an already existent open source library for the frequency detection) that shows the value on the screen. I have to spend only some hours to adjust the library, but i Lisää
