Determining when a sound above a certain frequency is played on iPhone
- by eagle
I'm wondering what's the easiest/best way to determine if a sound, being recorded on the iPhone mic, is above a certain frequency.
My guess is that I would need to use the Audio Queue Services since I don't need to record the audio to a file.
I'm using SDK 4.0, so I can use the FFT functions in the Accelerate framework if needed.
