Hi
By the way, for the moment I use FFTW for the frequency identification.
Is there a way to identify a frequency with quite high precision without
computing a big spectrum analysis ?
depending on your signal you could just count zero-crossings (with some
filtering to get rid of any DC and higher harmonics)
