Free guitar tuner software for linux

GuitarTeX is a tool for guitarists who want to print good looking and easy to play song sheets or song books from their chord or chordpro files. It uses the well known chord format with several extensions. The program was developed on a Linux system, but it should run on any other Unix system which has a Perl/TK environment.
It is based upon an idea of Martin Leclerc and Mario Dorion from Canada and their program Chord (Version 3.5 from 1993). To use GuitarTeX, you need to have knowledge of the Chord program (explained later). Though the LaTeX text processing system is used by GuitarTeX, you dont have to know very much about it. GuitarTeX produces Postscript or PDF output automatically (if you want). The Chord directives supplied by GuitarTeX are described in Chapter 5.
Main features:
- Graphical user interface with integrated editor and syntax highlighting
- Prints good looking song sheets including guitar chords without using monospace fonts

- contents, headlines with page numbering, chord table and index

tunerd is a very simple daemon to control an FM tuner. I found that most FM tuner control programs opened the device (/dev/tuner), set the property (frequency), and closed the device again. This is fine on most tuners, but my USB FM tuner always turned off when the device was closed. I needed a program that would always keep the device open - hence tunerd.
Because tunerd always keeps the device open it needs some way to be controlled so that other programs can talk to the FM tuner. To allow this tunerd will listen on a TCP/IP socket for requests to set/get various FM tuner attributes. This package also has another program called setuner which controls the FM tuner by talking to tunerd. I use this to control my FM tuner from a web page and cgi-bin script.
Compile instructions:
./configure
make
Enhancements:
- Fixed minor code compatibility problems and updated configure scripts
