View Full Version : Digital Radio audio quality

2005-06-10, 03:35
I'd like to integrate DAB into my SlimServer environment and am not sure which makes more sense - DABBAR with a USB DAB, or Alien BBC. I know that AlienBBC alllows access to offline content as well as live broadcasts, but my question is whether there is a substantial difference in audio quality between the two approaches. Any thoughts?

You'd have to check the bitrates used on the various online BBC stations, and compare it to DAB to try and get an idea of a comparison.

But bearing in mind the different compression systems (Real Audio vs. Mpeg L2) it will be hard to do.

As a country we have the worst DAB quality of anywhere in the world and I predict it will get worse still, as time goes on, since the economics of the service almost guarantee it, so I suspect it's a bit of 6 of one, half a dozen of the other!

Neither come remotely close to the FM broadcasts, in terms of quality, I wonder if a way could be found to stream a feed from an FM tuner to the SB for best quality?

That all said, the convenience and access of either DAB or the Internet-based stations are a huge bonus to me, and the 'Listen Again' stuff really adds the icing on a great cake!

I use both, FWIW my feelings are:

DAB (Psion Wavefinder/DABBAR) - slightly better quality than AlienBBC, also more reliable and quicker to play (I listen to BBC R3, R4, R7)

Alien BBC - listen again - worth it just for that!, however often have problems getting some programmes to play.

How about connecting a freeview or satellite box?

DAB bitrates are pretty poor and Freeview, for example, gives higher bitrates.

dSw - do you know of a freeview card or adaptor that will feed slimserver in the same way that DABBAR or Alien BBC can?

Sorry mate - no idea of what kind of feeds DABBAR or Alien BBC can take (or Freeview cards can provide, for that matter).

It might be worth you taking a look at the AV Forums and DigitalSpy websites for opinions on Freeview cards.
