The configure() method of the AudioDecoder interface enqueues a control message to configure the audio decoder for decoding chunks.

config

A dictionary object containing the following members:

codec

A string containing a valid codec string. See "codecs" parameter for details on codec string construction.

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.

None (undefined).

TypeError

Thrown if the provided config is invalid.

InvalidStateError DOMException

Thrown if the state is "closed".

NotSupportedError DOMException

Thrown if the provided config is valid but the user agent cannot provide a codec that can decode this profile.

The following example configures the audioDecoder with the opus codec.

audioDecoder.configure({
  codec: "opus",
  sampleRate: 44100,
  numberOfChannels: 2,
});
