OfflineAudioContext

open external class OfflineAudioContext(contextOptions: OfflineAudioContextOptions) : BaseAudioContext(source)

An AudioContext interface representing an audio-processing graph built from linked together AudioNodes. In contrast with a standard AudioContext, an OfflineAudioContext doesn't render the audio to the device hardware; instead, it generates it, as fast as it can, and outputs the result to an AudioBuffer.
