Maximum amplitude of a FFT signal…HELP!!!

April 2, 2009 | 4:17 pm

Hello everybody,
I have just started to study how to create an external for Max/MSP 5 using the SDK.

I want to create an object that analyze an audio signal in real time, using the fft.

My goal is to find the maximum amplitude value (in dB) of the fft signal, and the relative frequency.

Has someone already implemented a similar object?

Do you have any suggestion?

Other question: how can I use the object fft (or better pfft) inside the C code? Is there some predefined function?

HELP!

Thanks in advance

Why not use tristian jehan’s analyzer~ set of objects ? Sounds like they might be useful to you
