Web Audio API
Abstract
The Web Audio API (webaudio) describes a high-level JavaScript API for processing and synthesizing audio in web applications. The primary paradigm is of an audio routing graph, where a number of AudioNode objects are connected together to define the overall audio rendering. The actual processing will primarily take place in the underlying implementation (typically optimized Assembly / C / C++ code), but direct JavaScript processing and synthesis is also supported
Current Status
The Web Audio API specification is currently in a draft stage.
Firefox currently supports the incompatible, Mozilla-specific Audio Data API, but it is marked as "deprecated" in favor of the W3C standard. Work has started to support the new Web Audio API in Firefox. The Bugzilla bug 779297 was created to track progress on implementing this standard.
