Official.fm Labs is doing its part with a set of audio decoders built on top of the Aurora.js framework, also created by them. A few weeks ago, FLAC.js was released
enabling web developers to add support for FLAC files to their apps via native web technologies.
The new AAC.js library does the same for AAC files, popularized by Apple and the iTunes Store. AAC files are among the most common, second only to MP3s, so support for them is important to any music app on the web.
You can check out the source code for AAC.js
