NAME
       gtkguitune - KGuitune

SYNOPSIS
       gtkguitune

DESCRIPTION
       This  manual page documents briefly the gtkguitune program.  This manual page was written for the Debian GNU/Linux distribution because the
       original program does not have a manual page.

       Guitune is a linux program for tuning guitars and other instruments by using the method of Schmitt-triggering, i.e. counting the number	of
       triggerings between two trigger levels in a certain amount of time.

       With  FFT  you need many samples to archieve the accuracy needed for tuning instruments. You often get times of around 1 second between two
       measurements and the computer is quite busy in this second calculating the FFT. Using Schmitt-triggering you get a measurement  every  10th
       of a second or even less (depending on the sample frequency you use). Most of the time the computer only waits for the samples.

       The  Trigger levels are adjustable. For a pure sine-wave the trigger levels could be zero. But for a wave wth overtones like the one in the
       figure above you need a non-zero triggerlevel. It is preadjusted to a level of 60% of the current maximum which should be able to deal with
       most instruments.
