The MediaElementAudioSourceNode Interface.

The MediaStreamAudioSourceNode Interface.

There are two other node types that Microsoft Edge implements that apply to specific use cases. Microsoft Edge supports all of the following Web Audio interfaces and node types: There are oscillators to generate random signals ( OscillatorNode) and many more. These include effects that can pan audio across the sound stage ( PannerNode), precisely delay individual audio streams ( DelayNode), and recreate sound listening environments, like stadiums or concert halls ( ConvolverNode). Web Audio goes further, and includes a range of audio effects that are supported through a variety of processing nodes. Both can connect audio sources through gain and mixing nodes to play sounds with accurate time synchronization. In concept, the AudioContext is very similar to the audio graph implemented in XAudio2 to support gaming audio in Classic Windows Applications. These get connected to different processing nodes, and eventually to the AudioDestinationNode, which sends the output stream to the audio stack to play through speakers. SourceBufferNodes are typically used to hold small audio fragments. The variety of nodes available, and the ability to connect them in a custom manner in the AudioContext makes Web Audio highly flexible. The AudioContext defines the audio workspace, and the nodes implement a range of audio processing capabilities. These start with the AudioContext and a variety of Web Audio nodes. Web Audio is based on concepts that are key to managing and a playing multiple sound sources together.

This release adds Microsoft Edge to the list of browsers that support Web Audio today, and establishes the specification as a broadly supported, and substantially interoperable web spec. Web Audio is specified in the W3C Web Audio Specification, and continues to evolve under the guidance of the W3C Audio Working Group.

Additionally, Microsoft Edge includes Web Audio support for live audio streams using Media Capture and getUserMedia, and also works with an updated HTML5 Audio Element capable of gapless looping. Web Audio provides tight time synchronization not possible with HTML5 Audio Elements, and includes audio filters and effects useful for enthusiast media apps.

Today, we are excited to share details of our Web Audio implementation in Microsoft Edge. In March, we released initial preview support for Web Audio to Windows Insiders.
