Add to this the fact that most HD-Radio broadcasters, don't actually use
any bit rates higher than 40k. At 40k even aac+ sounds poor, and
presumably the HD-Radio codec will sound even worse.

And that is the sad reality of the situation.

And if the FM band is ever cleared of analog stations, by the time
that that happens, iBiquity HD radio will be a dinosaur in the
broadcasting world, like eight tracks cassettes are in the CD world.

The question listeners and radio stations should be asking is, what
digital system could be developed for future use, rather than
continuing with the present failures of DAB and HD(tm) radio.
