Hi list,

I need to analyse the low-frequency (1 to 5 Hz) content of a non-audio signal.

So I'd like to proces Fourier Transform of my low-frequency, low sampled signal, within PD.

As my incoming signal is low-sampled at 25Hz (coming from a camera), i think i can't use fft objects designed for audio processing.

Do i have to rewrite an fft algorithm within pd, for low-frequency processing, or does this exist yet ?

Has anyone built such a process in PD ?
