Please use the most up-to-date spec available:
https://w3c.github.io/media-source/#audio-track-extensions

As implementors, we should always look at the most recent version of any spec,
to not risk implementing bugs that have already been fixed, etc.

If you rename this file to AudioTrackSourceBuffer.idl and do the same with the
implementation files, you can drop ImplementedAs. BaseInterfaceExtension is the
usual pattern, see e.g. DocumentFullscreen.idl and the many
HTMLMediaElement*.idl
