DAVID WROTE: "The marketing just began last monday. The A codec was dreadful until early last year, and there were practically no stations on until lat 2004... except experimental ones. There was no production line transmission equipment till November, 2004, for stations. And the HD2's started in ernest the beginning of this year."
Next year, perhaps August 2007, I fully expect to read how the "REALLY REALLY, FINALLY REAL" HD Radio marketing campaign is getting underway.
The "A codec"? Are you talking about the HDC codec? It's really just a licensed version of the AAC+ codec. The AAC+ codec has not really changed and does not need to change. It's the best general-purpose audio codec out there, head-and-shoulders better than the others. Even a 24k stereo AAC+ bitstream sounds impressive.
For those of you with high hopes for HD Radio, let me bring you back down to earth. Go to the Bridge Ratings website at the link below to see their updated projections for the future of radio delivered via HD Radio, XM, Sirius, cell phones and Internet radio (wired and wireless). Projections out to 2010 should be fairly accurate.

Don't miss the tallest cream-colored bars signifying Internet radio. That's where the REAL competition lies for reach and time-spent-listening. For all of the reasons we have discussed on this board, HD Radio will be a bit-player at best!
