I had a listen to this for the first time today and I'm not ready to vote yet, but I wanted to throw out a couple of comments about the issues people seem to be experiencing with the disc...
1) Shout sounds 'bad' or 'worse than the rest of the album'. I think the problem here is the drum machine that dominates this track. Technological limitations meant that early drum machines like this one used really poor quality samples - the one used on this track doesn't sound like it's much more than 8 bit. As a result, all the percussion sounds very brittle and grainy, especially in the top end. I think this harshness is also exacerbated by the gating and/or compression used on the rhythm track to give it that big punchy sound. If you listen to the vocals and other instruments on this track they sound just fine, or at least as good as the rest of the album.
2) The Vocals are buried. I felt this way too, that they were at least a few dB too low, so I took a few of the 5.1 tracks in to Nuendo along with the original stereo mix as well as the stereo remix determined to find that there was a problem, but to my surprise, there wasn't - the levels between the 5 full range channels are almost exactly balanced. When you downmix the 5.1 to stereo, it sounds almost exactly like the stereo remix, which sounds pretty much like the original stereo mix. So what is going on then? There is what I would call a 'presence problem'. 'Presence' in audio is the area roughly between 2kHz and 8kHz, and when you boost the frequencies in this region, it makes whatever vocal or instrument you've applied that boost to seem more dominant, or 'present', even if technically the overall level of that track in the mix isn't any higher than any other track. Looking at the 5.1 mix in a spectrum analyser, I noticed that a lot of the activity in the rear speakers was boosted (either on purpose or just because thats what it naturally sounded like) in the presence band. As a result I think some of this stuff overwhelms the vocals, which are arrayed across the front three speakers. For example on track 2 'The Working Hour', the keyboards are mixed so that the low and low-mid frequencies are in the front speakers, and the middle (presence!) and high frequencies are in the rear, and the guitars (which are all in the 'presence' band are entirely in the rear. When all of this really gets going the vocals seem to get obscured as a result, especially if you're sitting anywhere near the rear speakers. This is probably exacerbated a bit by consumer grade home theatre speakers, which are a big more forgiving in the midrange area (ie they have a natural mild 'happy face' reproduction curve, accentuating treble and bass) compared to studio monitors which expose every little wart, especially in the midrange.
Here are a couple of spectral analysis plots that illustrate what I'm talking about - first is one from a random point in 'The Working Hour' - the green plot represents the front channels, and the pink plot represents the rear channels. Notice how much the rear channels are poking through between 1kHz and 4.5kHz, the heart of the 'presence' area:
Now compare that with Steven's 5.1 mix of 'The Ballad Of Peter Pumpkinhead' from XTC's Nonsuch - it was the closest in age/style to TFF of Steven's mixes I could think of. Notice that the rear channels don't overwhelm the fronts at all, especially in the presence band:
When you're doing a stereo mix you have to carefully 'carve out' space for each instrument and voice to sit in the sound field using EQ, so nothing obscures anything else. With a 5.1 mix you have so much more space to work with, so you don't need to worry about things being obscured - in fact it's almost the opposite, you need to worry more that everything stays glued together. The fact that 5.1 downmixes to match the stereo mix so perfectly makes me think that Steven was almost 'too faithful' to the original stereo mix in doing this mix and that maybe a little more outside the box thinking may have perfected it. I'll have to give the disc a few more listens before I come to any definitive conclusions, but this is how I'm feeling at the moment.
