The AudioDecoder() constructor creates a new AudioDecoder object with the provided init.output callback assigned as the output callback, the provided init.error callback as the error callback, and the AudioDecoder.state set to "unconfigured".

init

A dictionary object containing two required callbacks.

output

A callback which is passed a single argument of an AudioData object.

error

A callback which is passed a single argument of the error that has been thrown.

In the following example an AudioDecoder is created with the two required callback functions, one to deal with the decoded chunk and the other to handle errors.

const audioDecoder = new AudioDecoder({
  output: processAudio,
  error: onEncoderError,
});
