5.1 mixes seem to ignore the four quadrants, which many engineers emphasized in 4.0.
Jon can you do screenshots with spectral analysis of the waveform?Here is a look at the 4.0 Alan Parsons mix audio wav files as extracted with AudioMuxer from the Blu-Ray Disc:
"The 4.0 mix has been coverted with LFE track for the sub and center channel"
im confused
so That means it is 4.0mix through 5.1 channels, they simply pit the low low effects in the center and sub?

Since it is quad there will be sound coming out of your front left/right and surround left/right speakers. Also, if your system configured for bass management (i.e., your front/surround speakers are not full range and you have a subwoofer) then the lower frequency portion of the audio will be redirected to your subwoofer.
AFAIK when playing 5.1 music, the audio coming out of a subwoofer in a 5.1 system is more from bass being redirected from the other speakers (bass management) than actual LFE content since LFE is designed for movie audio. But for 5.1 music the sound mixer may throw some content into the .1 (LFE) so that nobody complains about there not being any LFE

QL, I'm pretty sure you are wrong.
The 4.0 mix is indeed ONLY 4.0. Look at the wav files above. Now, your reciever setup may be taking the 4.0 mix and creating a .1 and a center channel, but there is no fake .1 or C channel on the blue ray. It's straight 4.0.
So, for those with 5.1 systems, your center speaker and sub will be silent (unless your receiver creates audio for these). Because of this, you should have full sized rears to match your fronts, just like the old quad days. Of course, you could listen and get the surround with smaller back speakers, you'll just lose the lower freq's that are in the rears.
Oh, so this is why new Blu-ray movies don't come with LPCM anymore, and have switched to dts HD MA. The studios must not like the idea of these boxes being used.
