If this has already been discussed, please mention. I initially began reading the links and releases with excitement, but the further I looked the less excited I became. I would be interested to hear people's comments that have a better understanding of "HD Radio".
Outside of "HD Radio", sometime in the future I'll be giving "XM Radio" a shot with a digital out, and toying with different DAC outputs and probably grabbing a decent vintage FM radio as well, but I'm curious of HD Radio simply from a curiosity perspective and possibly a car listening perspective more than anything "audiophile."
Grabbed from Slashdot --
"nfranzen submits this story/advertisement: "Yesterday, I had the opportunity to buy the first High Definition (HD) Radio in the United States. HD Radio, invented by iBiquity Digital, adds a digital channel to the sidebands of an existing analog FM signal. The technology is still pretty new, but I can tell you first-hand that listening to my favorite local FM station in HD sounds just like I am listening to a CD. Well, except for the commercials (grin). Here are some links to local TV news coverage and a news release for more info. HD receivers will hit the open market following the Consumer Electronics Show next week in Vegas." We had an old story about the FCC approving these digital broadcasts in the FM radio bands. "
