5.1 ch Audio with wrong channel distribution 2011-12-23 18:09:25 I have various Blu-Ray rips of live concerts with 5.1ch audio.Recently I noticed that in most of them audio data seem to be improperly assigned to different channels.Correct me if I am wrong, but this is how I see the "proper" distribution of audio among channels:Left and Right should contain music being played on stageCenter is Vocals and some Solo instruments, like guitarSide L/R are hall noise and echo, and LFE is bass.Assuming that is correct, here is audio sample with such distribution http://www.hydrogenaudio.org/forums/index....ost&id=6810and its waveform, as seen in Audacity http://www.hydrogenaudio.org/forums/index....ost&id=6814The problem is, however, that out of all concerts I have, only one has such audio. All the others have Vocals mixed with Left & Right, as in 2.0 audiotrack, while the actual Center channel contains quite weak and distorted signal, as if it was "rear center" or something. Other channels are intact, though.Same song, other BD:http://www.hydrogenaudio.org/forums/index....ost&id=6813http://www.hydrogenaudio.org/forums/index....ost&id=6815I thought it could've been ripper's mistake, but then I obtained BD-ISO, and it has the same problem.Unfortunately I don't have 5.1 sound system, so I can't judge how it should sound, but I suppose the first one being better anyway.Therefore my questions are:Is such "wrong" distribution really common for blu-rays and what is considered to be "proper"?Is there any way to reconstruct proper distribution, so that I will have vocal-less Left and Right?The usual method of cutting common between L&R like in any stereo audio doesn't fit quality requirements, so I thought maybe I can use existing center channel, even though it sounds wrong. The reason I need them is that I want to create instrumental collection of songs being performed on stage, by extracting music-only L&R. I already successfully did it for songs from first BD.
