This is good news. I'm sure SW will make something good of this but I find this information a bit worrying
"these original tracks don’t quite run in sync, so Steven had to cut them into parcels."
I would hope there are better ways to re-sync those tracks, like
ndiamone has suggested.
This is a misrepresentation of what has occurred.
The problem, as anyone who uses old tape based systems will be very well aware of, is that not all tape machines run at exactly the same speed. So, when we look at the 24/96 stereo masters (straight out of the archives and re-digitized at this resolution especially for this release series) and try to achieve sync with the new multichannel mixes, we see immediately that some tracks are running at slightly different lengths. I have to state categorically that there are
no discernible pitching issues here and trying to fiddle with the timing (utilizing a time stretch algorithm, followed by a pitch algorithm) will run an unacceptable risk of actually
introducing a problem (artefacts) where there was no problem before.
Let's move on to the statement about "cutting into parcels".
In actuality, the transfers have been cut into separate
tracks. In this manner, once I get the streams from steven I can sync up to the stereo masters by recreating the gaps & crossfades in the original stereo masters so that the start points of every track match perfectly - this has to be done, or else the authoring will not be done properly to spec unless a downmix is added to the surround mixes (never on my watch) because any group in an Audio_TS
must be capable of being presented in stereo.
We achieve this by utilizing PGC Block authoring, which works by doubling up on the tracks in every group - importthe multichannel mixes as stream #1, then the stereo tracks as stream #2, then the track imagery & menus will work on both sets of mixes without having to either double up on menu assets or group assets.
Why is this necessary? Simply because every group has to be playable in stereo, or else we could well get the situation where a stereohead will attempt to play a muyltichannel mix, and as a result (if there is no downmix, or no dedicated stereo stream included in that group) will hear just L & R, missing out completely on any information in the C, LFE, LS/RS channels which is clearly not what is needed.
The solution?
Mix each track as a separate item, and crossfade to the original PQ marks in the stereo streams. So far out of 5 multichannel mixes delivered, we have been able to achieve this withoutresorting to time stretching or pitch shifting - and I defy anybody to tell the difference, pitch-wise. The differences really are negligible - we are talking seconds across a 15 minute track.
AGain, there are other things going on here too. How many of you own "Lizard" on CD? Did you know it is actually a 5 track album, yet when you load it into a player you will find much more than 5 index marks on the disc.
This is because several of the tracks follow the old "Prog Rock" habit of having subsections, almost like an opera does.
So Lizard looks like this on the sleeve:
1 - Cirkus
2 - Indooor Games
3 - Happy Family
4 - Lady Of The Dancing Water
5 - Lizard.
The mixes as supplied look like this:
1 - Cirkus
2 - Indoor Games
3 - Happy Family
4 - Lady Of The Dancing Water
5 - Prince Rupert Awakes/Bolero
6 - The Battle of Glass Tears
7 - Big Top
The indents on the actual disc look like this:
1 - Cirkus
2 - Indoor Games
3 - Happy Family
4 - Lady Of The Dancing Water
5 - Lizard (comprising)
5a - Prince Rupert Awakes
5b - Bolero - The Peacocks Tale
5c - The Battle Of Glass Tears (comprising)
5ci - Dawn Song
5cii - The Last Skirmish
5ciii - Prince Rupert's Lament
5d - Big Top
In summary, what appears to be just a 5 track album is supplied as 7 mixes, yet broken down on the disc indents to many more than this.
Check your CD - it will have marks at all these points. On this particularly long stream, you will see that because we are trying to match the stereo to the surround (out of necessity) the component sub-tracks in "Lizard" (the track, not the album) would have gone off-sync by around 15 seconds by the time of "Big Top" - which is not nearly long enough to make any audible difference on playback. On the DVDA the start times are all properly synced, yet anyone who does rip the tracks & try to align them up will notice the start points are all in sync, but the ends of the tracks rarely are - although I really cannot stress enough
there is no audible difference at all.
Hope this allays any fears that anyone has.
This is one hell of an ambitious project, and we are all putting an awful lot of time & effort into ensuring that it will be as good as it is possible to be - for both stereo & multichannel fans alike.
ITCOTCK aligned up with very little difficulty at all - total loss of sync is under 3 seconds at the worst case, and again, all start points are perfectly aligned. If old multitrack tape machines had been crystal locked for speed, then none of this would have happened. That ain't the way it is though, and exactly the same problems will have been faced many times over in the past. I seriously doubt that Abbey Road have the same machines that were used for the original Beatles sessions - so that remastering programme will have faced the same problems.
Going back - finally - to the sessions that Robert is talking about, I guarantee that all you will think is "Fuck me, this sounds
great"
