People rave about the audio quality on Blu-ray DVDs. Why?
A standard DVD includes an LPCM uncompressed 2-channel mix sampled at 48 or 96kHz with 16 or 24 bits/sample.
A Blu-ray DVD includes a Dolby TrueHD 5.1 surround mix sampled at 48kHz with 24 bits/sample and an LPCM uncompressed 5.1 surround mix sampled at 48kHz with 16 bits/sample (I think!).
OK, ignoring the fact that one is 2-channel and the other is 5.1, why is the quality of Blu-ray audio supposed to be a lot better than standard DVD audio? In some cases standard DVD should be better, eg 96kHz with 24 bits/sample.
What have I missed here?
