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 ?
For a 0.7 Hz precision with fft, I need 65536 samples, what will take a
lot CPU load every 1.5 sec.
Mario Lang has written a commandline tuner using FFTW, too.. It works fine in
realtime it seems. Maybe it's worth to take a look..
