Gilles Degottex <gilles.degottex@xxxxxxxxxx>: > JACK support is done ! > http://download.gna.org/fmit/ Great, best tuner there is. Very good note recognition, two "interfaces" to look at and tune to. Turned out I pretty soon started to use the "Error history", with strings it's enlightening. Thank you. * On startup fmit says "JACK: format = 16 bits Mono". The alsa backend in jackd is initialized with "creating alsa driver [...] 32bit". Does that mean the 32-bit frame that gets data from a 24-bit-device is truncated somewhere? In fmit? * Threshold for note recognition seems to be at about -40dbFS. E1 has energy above that much longer than E3 of course. So I get x seconds for E1 and about 1/6th of x seconds for E3. Setting "Volume threshold" in the configure dialog from 1% (default) to 0% renders quirky results. I don't understand "Components threshold". Would have tried but ... see below. Can there be something done about this? * Changing things in "Configure", saving and ok'ing crashes fmit. This is with a 'make features="enable-gui enable-debug" configure', is "enable-debug" the right argument here? INSTALL is a bit unclear about that.
