Chiptune.js

Version 2

This is a javascript library that can play module music files. It is based on the libopenmpt C/C++ library. To translate libopenmpt into Javascript emscripten was used. For audio output inside the browser WebAudio API ist used.

Please note: The compiled libopenmpt.js in this repository is based on an outdated version of libopenmpt. Newer versions contain bugfixes and other improvements. Download the latest version from the libopenmpt developers here and replace libopenmpt.js.mem and libopenmpt.js.
If you prefer to compile libopenmpt.js yourself (to save space or make custom changes) follow the instructions in the "Development" section.

Features

  • Play all traker formats supported by libopenmpt (including mod, xm, s3m, it)
  • Simple Javascript API
  • Pause/Resume
  • Tested with Google Chrome and Firefox
  • Play local (HTML5) and remote files (XHR)
  • Stereo playback
  • Module metadata
  • Looping mode

To do

  • Playback information (e.g. position, speed, bpm)
  • Mixer settings (e.g. sampling rate, resolution)
  • Seekbar support

Demo

See it in action here.

Just drop a module (e.g. from modarchive.org) on the demo page and enjoy.

Development

Download the latest emscripten SDK. Follow the instructions for your OS. Make sure emcc and em++ commands are available in the PATH.
Next download and extract the libopenmpt source code (unix like) from http://lib.openmpt.org/libopenmpt/.
Use this command inside the libopenmpt source folder to build:

make CONFIG=emscripten

If it compiles successfully these files (and a few more) will be created in the bin directory:

  1. libopenmpt.js is libopenmpt comiled to JavaScript.
  2. libopenmpt.js.mem is the memory initialization file libopenmpt.js will download/require it when loaded.
  3. libopenmpt_test.js (and libopenmpt_test.j.mem) is the libopenmpt test suite and can be run in NodeJS.

Only the first two files are needed for chiptune2.js.

Building Stylesheet

The stylesheet is build with SASS+Compass. To build this yourself, follow the Compass installation instructions, then cd into the chiptune2.js directory and use this command:

compass watch

The stylesheet .css file with rebuild every time you make a change to the source file in the sass folder.
