Hi. In case anyone inside this community cares, I'd just like to let you know that I was annoyed enough by the fact that there are two free software guitar tuners around which both require X Windows that I just wrote a text mode (command-line) guitar tuner for Linux which basically merges the strong points of both graphical programs. By default, it uses a very simple (Schmitt Trigger based) algorithm which is so cheap in terms of CPU time that it actually should run on ARM processors. Alternatively you can switch over to a FFT phase difference based algorithm which produces more accurate results, but can be quite CPU intensive. ALSA and JACK are supported as audio transport mechanisms. So if you ever felt the need to tune your electronic guitar exactly without using a tuning fork, have a look at http://delysid.org/tuneit.html Some sample output obtained from my guitars A string (it works with arbitrary notes, no need to only use A): lexx:/# tuneit -f -l 4 -j Note A ( 110.000Hz): -2 cents ( 109.868Hz) -- CYa, Mario _______________________________________________ Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
