Auriotouch, get musical note from frequency FFT
I'm developing a kind of guitar tuner.
I have a function that gives me the FFT, and the values of the FFt for each frequency.
How do I get the musical note from there? Do I have to chose the highest peak?

Is pitch and speed the same thing in audio programming context?
Pitch means "perceived frequency". Nice. But when I make pitch very low in OpenAL, sound plays a lot of times longer. If I make it very high, sound plays very short but with high frequency. For me, logically the consequence of making slower or…

I know the (pitch, yaw, roll) coordinate system has its own flaw mathematical-wise. However I really hope something instead or derived from this coordinates can be an alternative.
What I am try to do is moving the device (let's say it's an iphone)…
