I have a ch开发者_如何学运维ildren\'s iPhone application that I am writing and I need to be able to shift the pitch of a sound sample using Core Audio. Does anyone have any example code I could look a
I\'m trying to do some note recognition on mp3 or wav files. The prob开发者_如何学Clem is: How do I use the FFT on the files?
Ive been experimenting with the FFT algorithm. I use NAudio along with a working code of the FFT algorithm from the internet. Based on my observations of the performance, the resulting pitch is inaccu

I have simply pitch detection. Input (microphone) data are passed to fft routine, then I\'m looking for a pitch with maximum value It means:
I was looking to implement voicepitch detection in iphone using HPS method. But the detected tones are not very accurate. Performous does a decent job of pitch detection.
How do i get frequency using FFT? What\'s t开发者_StackOverflow社区he right procedure and codes?Pitch detection typically involves measuring the interval between harmonics in the power spectrum. The p
