Tuners for musical instruments on Linux

Like me, many other people have a hobby to play musical instruments and sometimes one has the hatred ready to tune their instruments (like the guitar for example) and other times one just wants to play and not waste time tuning to "ear". Well, there are some alternatives that will allow us to tune our instruments with free software.

Ingot Tuner

Lingot, which was originally developed for electric guitars, is a musical instrument tuner for GNU / Linux systems. This app can tune most instruments: from guitars to pianos. Also, it is very easy to use and highly configurable.

To use Lingot (Lingot is not a guitar only tuner) it is necessary to have a microphone or the instrument connected to the input port of our PC. Once connected, Lingot will show us the note we are playing and the frequency spectrum.

To install Lingot, we can download the sources and compile them. Although for Debian / Ubuntu users the packages are available in the repositories, so just a:

sudo apt-get install lingot

Gtkguitune

This is another tuner for instruments, but especially for guitars. GtkGuitune is an instrument tuner for GNU / Linux, which uses the Schmitt trigger method or Schmitt trigger; for example: counting the number of triggers between the levels of one trigger and another in a given time.
Using gtkGuitune is very simple, we just have to bring our guitar closer to the microphone and Guitune will regulate until we have the right sound.

This application is also available in the Debian / Ubuntu repositories, so for its installation it will be enough to execute a:

sudo apt-get install gtkguitune

Or failing that, we can access the sources from the following link.

FM Tuner

fmit (Free music instrument Tuner), although it seems to be a bit left out, it is also a free musical instrument tuner. It is a graphical application that allows us to tune our musical instruments with a history of errors and volume. In addition, Fmit provides certain advanced features such as: wavelength shape, harmonic ratio, microtonal tuning, among others.

Fmit is available for both Linux systems, such as FreeBSD and Windows. In addition, it supports captures through Jack, Alsa, PortAudio and OSS.

For users of Debian (and derivatives), Suse, Fedora and FreeBSD there are packages available on the official website.
