/**
 * The decodeAudioData() method of the BaseAudioContext Interface is used to asynchronously
 * decode audio file data contained in an ArrayBuffer. In this case the ArrayBuffer is
 * loaded from XMLHttpRequest and FileReader.
 * The decoded AudioBuffer is resampled to the AudioContext's sampling rate,
 * then passed to a callback or promise.
 * @param buffer An ArrayBuffer containing the audio data to be decoded, usually grabbed
 * from XMLHttpRequest, WindowOrWorkerGlobalScope.fetch() or FileReader
 * @param success A callback function to be invoked when the decoding successfully finishes.
 * The single argument to this callback is an AudioBuffer representing the decodedData
 * (the decoded PCM audio data). Usually you'll want to put the decoded data into
 * an AudioBufferSourceNode, from which it can be played and manipulated how you want.
 * @param error An optional error callback, to be invoked if an error occurs
 * when the audio data is being decoded.
 * @return the promise or null
