Delay from Inserts, How to compensate

[CisumBlue]

OK, I am using sessions with Auto Tune (EVO) and of course it induces a delay. I am seeing 1380 on the vocal tracks. So does that mean that this track is 1380 samples behind the way it was recorded? If so, how do I compensate. I am using L1 Max on the master track and it has a 64 showing so I assume somehow it is delayed by the L1. I can't notice the delay, to be honest, but obviously I want everything synced. Does this mean I have to put a 1380 short delay on every track that doesn't have a delay it before mixing? That seems kind of weird. What will happen to the auxiliaries I am sending the vocals to, like Reverb, compression etc. Will they then be corrected?

If someone can just explain to me simply how all of this should be handled. I really just realized there was delay on some plug-ins and it had never bothered me. Ignorance is bliss I guess.

Delay on a master track won't matter unless you are trying to overdub. As for the AutoTune delay, I would send to a new audio track, record the processed(tuned) audio. Mute the original track and use Tab to Transient to find the exact start of the original, then spot the new audio so it lines up there. I do this with Melodyne'd tracks and it works perfectly.

I already told you in a different post to watch these videos

http://www.screencast.com/users/peed...ders/tutorials

They are pretty comprehensive.

If you still have questions after watching, then people will be able to give you better specifics than explaining the whole process...

There is no "simple" way and there really aren't any shortcuts unless you buy mellowmuse ATA... But you still need to understand what is going on and it sounds like you don't..

Thanks Flommer - I had watched the videos and am still confused. Sorry to bother you.

Hey you're not bothering me.. I just noticed that this seems like the same question twice..

So what exactly is confusing?

Think of like this:

You have the raw tracks which need to be all compensated to each other based on the worst offender. If your worst offender is 1380, then each other track needs to be delayed by that amount. What albee is suggesting is to not use a plugin like autotune in "realtime". You record the effects of the plugin, make sure it's aligned and then forget about it..

Then you have the parallel effects busses, like reverb or delay, that need to be compensated against each other AND against a submix of all the DRY (from the videos) raw tracks. So if you have 2 different parallel reverb auxes with different plugins on each that have different amounts of latency (lets say that one has 100 samples and the second has 200) then your dry aux time adjuster is set to 200, the reverb with 100 samples delay gets a time adjuster with 100 samples, and the 2nd reverb, the worst offender gets no time adjuster... You see how it adds up?

The master track delay doesn't matter because it is just the SUM of everything you are monitoring... It is not being listened to in parallel to anything, so it doesn't matter that what you hear is slightly late...

Like I said, it's not really simple... But if you figure out what is going on then going through and fixing things won't be that big of a deal..

Note that this is all happening at mixdown time. If you are still tracking, then you should avoid using plugins that cause delay in the first place.

Also it is good to figure out which plugins those are..

A very helpful thing would be if somebody had a comprehensive list of the delay caused by all the plugins out there.. I don't know if such a thing exists or would be practical.. But you can certainly figure out the plugins that you have..

Well Auto Tune is a big one and it is helpful to sing harmony to a track that is already tuned. Really what was confusing is this...I often use auto tune and I solo the track and bounce it to disk and then import it as the corrected track. If I "spot" it back to the correct spot is it then 1380 samples off from where it should be? If that's true I could just move the corrected track back 1380 samples rather than go in and place delay on every other track. Assuming some other track has a different delay, say 64 like Peeder's, then placing a 1380 on the dry aux wouldn't work for that track. So that's kind of the issue. I'm not dumb, just ignorant :)

Also, it would be helpful if digi just added the automatic comp. If garage band has it why wouldn't PT.

Would that be possible at all? Plugin delays depend on their respective signal processing (also user parameters, think of adjustable lookahead or IRs of varying lenghts) and the chosen buffer size as far as I recall. Haven't been messing with DSP in some time, though.

Right that's what albee is suggesting. You fix it, shift it back then forget about it..

If I "spot" it back to the correct spot is it then 1380 samples off from where it should be?

This depends on what you consider to be "correct" or "where it should be". To me, the correct position is the same place where the original, uneffected audio is..

The dry Aux is not for dealing with individual track delays, at least not in the videos... That is for dealing with the delay caused by plugins that are on parallel effects busses...

Say you had 10 basic audio tracks and only one of them had a plugin that was causing delay. You could then bring the other 9 tracks together to an aux and use a time adjuster there..
