web.audio.AudioBuffer — clojure-interop/cljs-web-api 1.0.9

The AudioBuffer interface represents a short audio asset residing memory, created from an audio file using the AudioContext.decodeAudioData() or from raw data using AudioContext.createBuffer(). Once put an AudioBuffer, the audio can then be played by being passed an web.audio.AudioBufferSourceNode.
