LINGOT is a musical instrument tuner. It’s accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune other instruments.
It looks like an analogue tuner, with a gauge indicating the relative shift to a certain note, determined automatically as the closest note to the estimated frequency.
- It’s free software. LINGOT is distributed under the GPL license.
- It’s really quick and accurate, perfect for real-time microtonal tuning.
- Easy to use. Just plug in your instrument and run it.
- LINGOT is a universal tuner. It can tune many musical instruments, you only need to provide the temperaments. For that purpose, it supports the Scala project .scl format.
- Highly configurable via GUI. It’s possible to change any parameter while the program is running, without editing any file.

guitarix is a virtual guitar amplifier for Linux running on Jack Audio Connection Kit. It is free as in speech and free as in beer. The available source code allows you to build it on other UNIX-like systems too, namely BSD and MacOSX.
guitarix takes the signal from your guitar as any real amp would do: as a mono-signal from your sound card. The input is processed by a main amp and a rack-section. Both can be routed separately and deliver a processed stereo-signal via Jack. You may fill the rack with effects from more than 25 built-in modules from a simple noise gate to brain-slashing modulation f/x stuff like flanger, phaser or auto-wah.
