 * StreamerNode is an AudioNode that allows you to stream audio from a file or

 * source. Note: This node requires the build to use FFmpeg, and will throw an
 * error if FFmpeg is not available.
 *
 * @deprecated Use the `<Audio>` element with MediaElementAudioSourceNode for
 *   streaming audio instead to achieve the same functionality.
