iOS Polyphonic Guitar Pitch Detector

Project Budget (USD)

Project Description:
I am looking for real-time audio processing within iOS that will find what pitches are being played by a guitar, by listening to the microphone. Should be able to separate 1-3 notes (guitar strings) well, and 4-6 notes as reasonable as possible.

No graphics or UI are needed.
The expected app will rapidly listen to the microphone and update the screen with up to 6 UILabels holding the pitches of the played strings.

If only partially applicable, please describe limitations.
If you have a demo, that would be best!
