Beware of the oncoming Ibiquity spin storm...

M

MoldaMania182

from the ZuneHD! Unlike the last go around, this Zune runs on a state of the art nVidia Tegra platform and looks to be a hit as the preorders are coming in for next month's release. Now since this thing has an HD radio (that few will ever use) you KNOW Ibiquity will be ALL OVER this one claiming a surge in HD Radio "demand" from the consumer. HA!

I've got my popcorn...who else is ready for a good PR laugh?
 
I was playing around with my Insignia today, and couldn't hear any difference between analog and HD with very high quality earbuds. I plugged into my iPod to compare and the difference in audio quality was astounding.
 
If the HD side is being fed the same rolled-off high end as the analog FM stereo, then there won't be much difference (in an urban areas, where you can get full quieting on an analog fm stereo portable). If the station takes the time to do it right, and feeds HD with audio that's clean to 20khz, and does so at a high bitrate, it should sound noticably quieter, and with better separation. Of course it's quite possible, and far too common, for FM HD to sound WORSE than analog stereo! NO excuses...it happens, and shouldn't!

Unfortunately, that's mutually-exclusive with multicasting, which is supposedly HD Radio's "killer app".

Great system we chose here -- or, I should say, was forced upon us.

Oh come on! The iBiquity system is junk engineering no matter how you slice it. I listened to stations with additional channels and ones running only HD1 and it was the same thing. Sounded no better (in fact worse) on the multi's and about the same on the HD1's except for the compression artifacts and the total lack of mobile reception ability. The Insignia is a cute little receiver for playing with HD reception, but if I wasn't a long time broadcast engineer, meaning if I was a typical consumer, I would have taken the thing back and spent my $50 on some nice merlot. By the way, two of the stations I listen to here in Melmfus are exceptionally well engineered. The others maybe not so much, but it's still junk engineering. No matter who's screwing the wires together.
 
"OH COME ON" yourself. HD sounds fantastic ON WDAV in Davidson, NC...and they are my benchmark for how good it can sound. HD-1 at full bitrate, and no multicast. It's DRAMATICALLY better. DEAD SILENT background, and real dynamic range. When the announcers speak (on this audiophile-grade classical station), you can hear (through headphones) EVERYthing going on in the room. It's startligng how much detail you hear. Perhaps they sound so clean largely because there is no heavy processing to exaggerate (data) compression artifacts. But the compresion used on HD Radio is a kissing cousin of AAC+, which is the most transparent codec out there for low bitrate coding. I hate it when people tell me HD doesn't work, when I get 100+ mile (stationary) reception at my home every day (WMIT Black Mountain NC to my home in Wilkes County NC).
 
Oh come on. Is any of this worth it, if you're only able to receive a small handful of stations operating in HD? And the one's that do are pretty much standard off the shelf formats playing the same tired songs over and over and over.

The best part is, instead of a little shhhh you get silence..
And the echo is interesting too.

In case you have noticed, silence isn't golden. This is radio!

Why would I want to hear digestive problems, various clothing and studio noises, or a flea fart at fifty paces?

Isn't that why we have sound proof studios and directional microphones, so we don't have to hear all that noise?
