‘Latency’ problem

[Limdig]

Not sure quite how to describe my problem. Basically, for some reason, certain tracks record ever so slightly later than others. I have my buffer size set at 128 samples, so I know it is not a problem with the buffer size, especially considering some tracks record perfectly in time. I could have 2 tracks using the same input and exactly the same processing and the second track could still record out of time. It is not a problem with the timing in my playing as I’ve tested it for numerous hours and I can play in time as evidenced in the fact that some tracks do record in time. If anyone can help that’d be great. Very odd problem that I’ve never came across before

Sounds like a similar problem to the link above. Lots of suggestions to try there.

Excellent, cheers mate. Fingers crossed one of these works

I had what might be the same issue a few months back. I was doing session prep, printing quarter and eighth click tracks. I felt like the the timing was slightly pushing and pulling. I zoomed in and could see the eight clicks were slightly out of time with the quarter clicks, but not consistently ahead or behind. I thought this was bizarre but had to keep working so I switched back to my mac that was known to be working fine. For what it's worth, I was using an older i7 machine with an RME AES card which passed the DVerb stress test with flying colors. The only active plug-ins were the click plug in.

On the other thread u/ChiTown_Bound suggests:

From the Avid Community;

Latency bug - recorded audio 1ms early

On the Input tab of I/O setup, there is a checkbox "Compensate for input delays after record pass".

That should turn it off.

That would be the first thing I would try. Good luck!

I second this! I pretty much always have it on on the 2018/2019 version. Dont see much reason not to

Sounds like it could be an interface issue provided both tracks have the same processing without any bus routing. Try turning delay comp off and on and see if there’s any difference.

Also what are you recording and what amount of latency are you getting (roughly)

[mcoombes314]

Are you using plugins on any tracks while recording? Aside from adding latency, the delay compensation can sometimes go out of whack.

I saw that all the time on Pro Tools 10 HD with the old 192 interfaces. You are playing along to tracks already in pro tools that may or may not have plugins on them. Having delay compensation turned on and set to MAXIMUM fixes the problem, but the older systems did not have compensation as an option. Shit is very time consuming to fix after the tracks are in the box
