The AudioEncoder() constructor creates a new AudioEncoder object with the provided init.output callback assigned as the output callback, the provided init.error callback as the error callback, and the AudioEncoder.state set to "unconfigured".
init
An object containing two required callbacks.
output
A callback which takes a EncodedAudioChunk object as the first argument, and an optional metadata object as the second. The metadata object has one member, decoderConfig which has an object as its value containing:
codec
A string containing a valid codec string.
sampleRate
An integer representing the number of frame samples per second.
numberOfChannels
An integer representing the number of audio channels.
description Optional
An ArrayBuffer, a TypedArray, or a DataView containing a sequence of codec specific bytes, commonly known as extradata.
error
A callback which takes an Error object as its only argument.
In the following example an AudioEncoder is created with the two required callback functions, one to deal with the decoded frame and the other to handle errors.
const audioEncoder = new AudioEncoder({
output: processAudio,
error: onEncoderError,
});
