Free tuner software for linux

QTuneroid is a musical instrument tuner, designed to tune musical instruments on PC using a microphone or by directly connecting the instrument to the PCs sound card.
This program actually is a fork of Tuneroid by Jozef Kosoru (check his page at "http://www.uid0.sk/zyzstar/?tuneroid" ) which i made because i needed a good tuner, but dont want to use huge and sluggish KDE desktop, nor even install KDE libraries. So i ported Tuneroid to pure Qt and made some tweaks to UI slightly...
Enhancements:
- small ui fixes
- several build fixes

Deluxe Tuner is a GUI that gives you the full control over menu creation with Deluxe Menu. Deluxe Tuner allows Web developers to create DHTML navigation systems.
Deluxe Tuner creates and configures Deluxe Menu, creates and sets individual styles, saves and loads ready-to-use .js files, generates and saves Google XML Sitemap, generates search engine friendly code, generates and saves Sitemap HTML, supports real-time preview, supports many visual effects, and has many ready-to-use templates.
Enhancements:
- This version adds search engine friendly menus, site map creation, Google Sitemap support, support for Deluxe Menu 2.0, an option to enable or disable copying of menu files when saving, and minor bugfixes and changes.

Amarok XM Tuner is a script that allows playing of xmonline channels through Amarok. Based on a shell script by B. Galliart it requires python and pycurl. You must have a valid xmonline account. The tuner is opened from the playlist.

tuneit is a simple command-line instrument tuner for Linux.
It uses two different algorithms for pitch detection. By default, a simple and fast Schmitt Trigger based algorithm is used to detect the fundamental frequency of an instrument.
For better and more reliable results, there is an alternative FFT based algorithm which is much more CPU intensive.
As audio capture backends ALSA and JACK are supported. By default, tuneit will try to use the hw:0,0 ALSA device.
Options:
tuneit [OPTIONS...] [captureDevice]
Valid options:
-f Use the more CPU intensive FFT based algorithm
-i List available input ports and exit
-j Use JACK as the audio transport system
-l LATENCY Measurement window size in 1/N seconds (default is 10)
-r RATE Set desired ALSA sample rate (default is 48000)
-t HERTZ Tune the A note of the scale (default is 440.0)
Enhancements:
- Now uses the floating-point version of FFTW3 and in-place transforms for better performance when using the FFT algorithm.
- Fixes to support compilation with GCC 4.0.

This is a nice instrument tuner for GNOME 1.0. There is a compact very simple interface. There is also a console version and a GNOME 0.30 version avaialble.

It was derived from the original gtune utility which was a console program. It uses FFT routines which are quite slow and I dont think it should be run on anything below a pentium class computer and I reccomend a P166. This new version (0.10) now works for the more recent releases of GNOME, and is simpler than the original. It also now compiles two targets, gtune and gtune_console, so you can use console mode gtune if you want to.

You can download gTune for Gnome 1.0 source here, or you can download a staticly linked version of gTune 0.10 here. All you need to do is uncompress it into a dummy directory and execute the command "./runme". I hope the next releases will use the autoconf stuff, but this program is very simple anyways.

This new version isnt perfect however, it now determines intervals on its own, but Ive only been able to test how it does it on my machine. It works perfectly on mine, and should on your, but be careful the first time you run it and mail me if you have any trouble with it. I dont want to scare you off, I dont anticipate anything going wrong (did I just jynx it?).
