Summary

The Web Audio API 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.

• Note: for Linux platform, in order to activate this feature, you need to go to about:config and set media.gstreamer.enabled to true
