## The Web Audio API
|
||||
|
||||
|
||||
The Web Audio API is currently still under development. However WebKit browsers have started an implementation of the proposed specifications which can be found at: [w3.org](http://www.w3.org/TR/webaudio/).
|
||||
|
||||
The WebKit nightly builds try to keep up with the editors draft version of the specifications [w3.org](https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html)
