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.
