Aurora.js is a JavaScript framework that simplifies writing audio decoders, handling binary data, the demuxer-to-decoder pipeline, and abstracting browser audio APIs for playback. It ships with LPCM, uLaw, and aLaw support and is extensible via codec plugins like MP3.js, FLAC.js, ALAC.js, and AAC.js.

Use cases

• decode and play mp3 files in the browser with javascript
• play flac audio in browsers without native support
• build a custom audio decoder in javascript
• decode audio files in node.js
• play apple lossless alac files on the web
• abstract browser audio apis for decoded audio playback

When to choose

• you need to decode or play audio formats unsupported natively by the browser
• you want a pluggable framework for building JavaScript audio decoders
• you need consistent audio playback across browser and Node.js

When to avoid

• you only need to play formats the browser already supports natively via <audio> or Web Audio API
• you need a maintained, actively developed solution
• you need high-performance or low-latency decoding
