Tuner library for iPhone OS(repost)

We need a musical tuner library for iPhone OS that can: * Play a certain tuning note on a certain pitch * Recognize the note played by a musician and compare it to the configured pitch. It must be able to display the difference in a graphical way. The settings that must be possible: * Setting the note to hear. * Set the pitch. ## Deliverables The library should be functional equivalent to the attached JAVA example. A quick explanation: # These method are for playing a note: --public void playNote(String name) --public void stopNote() --public boolean toneActive() # These methods for the listening to the microphone input: --public void powerOn(boolean on) - set the tuner on/off --public void run() - The thread listening to the input --public void setPitch(int hz) - set the pitch of the A # General methods --public String[] getNoteNames() - get names of the notes --public String getStandardNote() - standard note (A) The implementation must be able to tune in multiple octaves. It is recommended to use the sample JAVA code to make a Objective C equivalent. This example doesn't include the FFT (DoubleFFT_1D class in the JAVA example).
