Topic: Matrix Time Stretch walk-thru for WaveLab 6.0............

[F.O.Bean]

I recorded Dopapod last nite, and didnt bother getting a patch in my 2nd M10. Well, after the show, Luke gave me the 2/8 PBurgh SBD on a SD Card of mine, and it stays aligned for about 15-20 mins and then goes out of sync :9   If anyone can walk me thru what exactly to do or just wants to do it instead of me, please shoot me a PM or post in this thread

Thanks in advance,
Bean

I am not familiar with Wavelab so don't know how different v5 and v6 are so the following may be spot on or completely different. The ts reference section has a tutorial for matrixing two sources in Wavelab5.

Oh my god, THANK YOU THANK YOU THANK YOU!!!! I looked everywhere for that

The only difference I know is that WL 6 can handle files UP TO 4GB

Nice find, flipp!

That tutorial does not discuss time stretch but rather syncing, which does not solve the question of timing issues. I've found that if there is drift you may need to cut the files up into smaller segments and may even need to remove very small segments of the file if the problem occurs during a song.

I've never really figured out how to use the time stretch, which would be really useful for analog sources. This is something I need to learn. anyone have a reference or answer?

[flipp]

There is a little discussion about that in the Mixing / Syncing Two or More Sources section of README1st! Links to frequently asked about topics... stickied to this section of ts.

note there is also a link to the Wavelab instructions there which Brian had the foresight to make a pdf file of since Fatah Ruark's original site is no longer available; other than poking around some of the links in that sticky I got nothin

Excellent.

i'm more than willing to take a stab too, if the FAQ doesnt help.

You're not alone. I've found my success rate in using the time-strech function to be < 10% (and that's being generous) and the issue is that each time-stretch operation can require 20-40 minutes or longer. I don't believe that WL6 has much in the way of support for newer hardware (i.e. quad-core processors), so it's possible this operation runs much quicker on a new version, but it's slow as heck in WL6.

Anyways... what usually occurs is that it takes me 4-5 tries, at least, to get the right amount of stretch. I probably just suck at math (I do) because I am seemingly off every time and it turns into a routine of trial-and-error.

And then there is the changes in drift over time as you mention. I've seen plenty of recordings lined up perfectly at the beginning and end, but seemingly very far apart in the middle. The rate of a word clock is not an absolute constant and it's definitely possible to see large variations in drift over seemingly short time-segments. When this happens, the only option is to start chopping up one of the files and sync in small portions. bleck.

Quite frankly, I don't think any FAQ or Guide is going to help anyone attempting this process and fair warning... if you are going to attempt this be prepared to spend a lot of hours trying to get it right with the possibility that the only solution is the 'chop' method.

[F.O.Bean]

I did the chop method recently, and IMO! It came out great, but it's not an easy/quick thing at all!

I've been working on time stretching a SBD source of the Joe Russo's Almost Dead show from Brooklyn Bowl with my audience pairs now for several weeks.  Both the SBD and my mics were recorded on a 744T but I was synched to the V3's clock and recorded at different bit and sample rates than the SBD that Bill Mulvey recorded.  This has been a monumentally frustrating task, one that I likely will not pursue again if and when I ever complete getting this done to my satisfaction.

I use Sony Vegas to stretch and it's a snap.  Send me the files and i will sink them up for you.  PM me if interested Eric.

Sweet ted, seeing the ringers tonight but tomorrow i'll try to send em down...have a dropbox account?
