Does anybody know what the frequency range of auriotouch is in FFT mode? Also, where is it defined in the code if possible. I’ve been digging through it, but am not very familiar with FFT or frequency calculation so am not having much luck. I’ve also done some googling and searching on stackoverflow and have not found results there either. Thanks for the help in advance.
An FFT’s frequency range is (sampleRate/2)/nbins – (sampleRate/2)
The aurioTouch code doesn’t set the sampleRate, but it does get the hardware’s sample rate at
aurioTouchAppDelegate.mm:300So, in the case of aurioTouch, the frequency range is going to be half whatever the current hardware sample rate is.
