how is it better than cd audio?p

i saw that george michael's new album is available in this format and wondered if it was worth getting it if the quality is better.

It sounds to me like the latest attempt at launching a hi def audio disc onto music buyers. See other previous failed formats for the outcome in SACD and DVD-A

It could be a live gig. You should check the details of the disc. Some blu-ray music discs i own are only in Dolby Digital and therefore of lower quality than cd but in 5.1 sound. I do own music Blu-rays that are in Dolby TrueHD and DTS-MA and are of much higher sound quality than CD. They really do sound very good and also in 5.1 sound. You do need a compatable amplifier or reciever to decode the higher bit-rate sound formats though. If you only plan to watch through your tv then you will only get standard rate stereo sound.
Its the same formats for blu-ray movies. You can only get access to the higher quality formats using a HDMI cable. Normal digital cables "max out" at 1.5mb.
As a rough guide. MP3 is usually 192kps or 256kps. CD quality is around 1411kbps. Dolby digital is 500kps but in 5.1 surround. DTS is 750kps. And the new Dolby True HD can go as high as 25MB a second! But the average movie on blu-ray is about 2.5 to 4MB a second. People usually argue if you can tell the difference or not but its usually down to how well it was recorded. Hope this helps anyone. Feel free to correct me if i am wrong about anything.

Sounds about right. Also Many amps/receivers these days are 5.1 so can effect the overall sound quality from Cd's SACD required purchasing a specialized and expensive player so was a total waste of time. I believe that BD cds allow them to be played on standard BD players (which many would use as players anyway).
I've yet to hear the sound from one but would guess that the quality would be closer to that of Vinyl (which has always been superior to all other formats)
