HD and "720" refers to image resolution. Not to the audio.



Not entirely - drop 'hd audio' into YT for a search.

Try this one (for instance):

Listen to that compression! (dynamic, not bitrate). Nothing remotely "HD"
about that clip :-(

This use of the term "HD" to refer to audio is a new and unwelcome
phenomenon, a BBB (Bull**** Baffles Brains) ploy on the part of companies
who should know better. It seems to refer to the use of lossless coding, but
wouldn't it be so much more accurate (and informative) to say "lossless"
rather than "HD"?

"720", of course, is a reference to the pixel height of the image, and very
clearly bugger-all to do with the audio.
