My right elbow hurts.
Howdy folks.
Recently I was having a look at my copy of this title in Audacity. (I have the Sony Music 2014 reissue in the 7" sleeve, catalog # EICP 10001.) I was a bit surprised to discover that the reverse-polarity problem in the rears has not been corrected, as reported in a couple of other threads here. Not only that, but the rears are out of time sync with the fronts - specifically, they need to be delayed by 0.6 milliseconds (600 microseconds) to bring them in line with the fronts. The LFE channel appears to have the same polarity as the fronts, as well as being in sync with them time-wise. The latter is hard to tell for sure because LFE is so bandwidth-limited, but it's probably a safe assumption since the polarity is correct.
The center channel on this release is yet another pointless low-level mono mix of all 4 quad channels (same as Rough and Ready), so I didn't waste any time checking polarity or time alignment - I just deleted it.
I'm passing this along for any of you who might have this ripped to PCM like I have. The improvement after correcting the polarity is obvious. The front-rear time alignment is more subtle, but I think it's also important, especially since this mix seems to have a lot of "dual-stereo" stuff going on. The mix sounds noticeably tighter with the delay corrected.
As always, any questions or comments are welcome.
