flac.js: A FLAC decoder in JavaScript
=====================================

The Free Lossless Audio Codec (FLAC) is a widely used lossless audio codec, which means that the audio is compressed
without any loss of quality. A decoded FLAC stream is bit-for-bit identical to the original uncompressed audio file.

The JavaScript decoder was ported from the FFMpeg project and the demuxer is based on the original
FLAC documentation. flac.js uses the
Aurora audio framework by ofmlabs to facilitate decoding and playback.

Demo

You can check out a demo alongside our other decoders
alac.js, MP3.js, and AAC.js. Currently flac.js
works properly in the latest versions of Firefox, Chrome, and Safari.

Authors

flac.js was written by @jensnockert and @devongovett
of Audiocogs.

Building

We use browserify to build flac.js. You can download a
prebuilt version from the Github releases page.
To build flac.js for the browser yourself, use the following commands:

npm install
make browser

This will place a built flac.js file, as well as a source map in the build/ directory.

flac.js depends on Aurora.js, our audio codec framework.
For detailed information on how to use Aurora.js, check out the documentation.
