In Reply to: RE: LPCM 5.1 uncompressed posted by JohanV on October 26, 2010 at 09:42:06
All three that you mentioned can have different bit depths and sample rates. Once the losslessly compressed formats are decompressed, they are in PCM format. The advantage of the losslessly compressed formats is that they take up less storage space on the disc and have a lower transfer rate than PCM, thereby allowing more space and transfer rate for the video.
It is odd that the majority of discs you have looked at are PCM because DTS-HD Master Audio has become the de facto audio standard for Blu-ray. Currently the codec is used for nearly 48% of the discs that have been produced so far. Dolby TrueHD makes up about 21%, PCM about 14% and the rest are lossy codecs (DTS-HD HR, DTS and Dolby Digital).
Follow Ups:
I have several BD concerts with LPCM 5.1 uncompressed (16bit/24bit) and I love the sound. Very neutral and it sounds great on my high-end stereo system.
It's not just the bits but the sampling rate. Many LPCM soundtracks seem to be 24 bit 48 kHz, so more bits and higher sample rate than redbook CD. I think the higher bit rate is probably more important than the higher sampling rate, at least when going from 44.1 kHz for CD to 48 kHz, but both will play their part.
