Temperatune

Temperatune is a simple tuner app that runs in the browser. Its key distinguishing feature from the myriad of other online tuners is its support for temperaments, which makes it much more useful for people who want to play early music in period style or music which does not originate in the traditional Western style (such as Arabic music). Of course, Temperatune doesn't have built-in support for all these types of music; instead, it allows the user to define temperaments as JSON files that Temperatune understands.

Browser support

I currently test Temperatune in the browsers I have access to, namely, Firefox and Chrome for Linux and Chrome for Android. However, it should work on any modern browser (meaning anything except Internet Explorer), and I hope to eventually find ways to test on more browsers.

Installation

To build and run Temperatune on your own machine, you should have Node.js and NPM installed (NPM comes bundled with Node.js). Then, to run the development version in a local web browser:

$ npm start

To build an optimized production version:

$ npm run build

You will find the resulting files in the build directory.

User-defined temperaments

The part of Temperatune that handles temperament definitions is actually a separate module, called simply "temperament". Please see its README for detailed usage on how to write your own temperaments or how to use the same backend in your own project. For your reference, the JSON files corresponding to the built-in temperaments can be found under the src/temperaments directory of this project.
