Tuner is a python application that can be used to tune a music instrument. It defaults to a guitar standard tuning, but I guess you could use it for any instrument.

Tuner just emits sounds. It does not process the soundcard input to assess the tuning. To do that, you should look at greater applications such as guitarix or Lingot.

Tuner does not aim at being actually useful. I wrote it as an exercise to learn python and GTK. I use it. Sometimes.

## Features

Playback through internal speaker or via soundcard output.

Configurable key set:

• Keys can be added or removed.
