# Chiptune.js

## I highly recomend using [chiptune2.js](https://github.com/deskjet/chiptune2.js) which fixes some important issues with this project.

This is a javascript library that can play module music files. It is based on the [libxmp](https://github.com/cmatsuoka/libxmp) C library. To translate libxmp into Javascript [emscripten](https://github.com/kripken/emscripten) was used. Audio output is implemented with the Web Audio API as specified by W3C.

## Features

* Play all traker formats supported by libxmp (including mod, xm, s3m, it)
* Simple Javascript API
* Pause/Resume
* Support for Google Chrome (also future Firefox versions)
* Load local (HTML5) and remote files (XHR2)

## To do

* Stereo playback
* ~~Looping mode~~
* Module comment text
* Playback information (e.g. position, speed, bpm)
* Mixer settings (e.g. sampling rate, interpolation, resolution)
* Seeking

## Demo

A demo is available: [DEMO](http://deskjet.github.io/chiptune.js/)

Just drop a module (e.g. from [modarchive.org](http://modarchive.org)) on the demo page and press the play button.

## License

As libxmp is LGPL 2.1 licensed all code derived from libxmp and libxmp itself remain under that licsense. Especially the libxmp.js file, which is basicly libxmp (plus a wrapper) compiled to javascript.
You can find a copy of the license text in the libxmp folder of the repository.

The code not derived from libxmp is MIT (X11) licensed.
