Delayed Audio

[Phil O]

Lately in DP10.11 I've seen a strange intermittent delay in recorded audio. Audio tracks are added and the project goes on in the normal fashion for overdub recording and then a track will suddenly be recorded about 150 ms late with no changes in set-up. This appears to be a random event. All takes will be fine then one track will print to the soundbite late. You can see it while the track is being recorded if you're zoomed in far enough. Do 4 takes on a vocal track and three might be fine but one is way late. I've tried changing buffer settings but no change. There are no glitches or evidence of loss of sync or buffer overflow. Everything sounds fine, just late.

Anyone else seeing anything similar?

Have you checked the drive audio is recording to? I’m wondering if it could be an access time or write error?

[Phil O]

I don't think it's a drive issue, but it could be. The drive I'm recording to has plenty of free space and is an internal on my cheese grater. Also, I was recording drums yesterday and I could see the hits being written in the Sequence Editor. They were being written late. It was clear that they were being written to the right of where the cursor was at any given moment. I'd hear the hit and the waveform was being written at the cursor position like it normally does, but the hit would be written to the display later in time. Very strange. I'm thinking it's a pre-gen issue. Dunno.

Has anyone found out what's going on with this? I'm having the same issue, and it's rendering DP unusable.

Plugins on master track appear to be the problem. Probably worth having this version of the solution tacked onto the end of this thread.

Strange that one can just create another "pre-master" aux, route everything that way that would have normally gone to the master, load up whatever plugs you want to use on that aux, and no problem, at least not in my case.

If you change the Buffer Size while a track is record-enabled, subsequent recordings will be mis-placed. At least in DP10.13, if I recall correctly the version in which I discovered this. I reported to MOTU and posted here about the issue.

To resolve, simply disable, then re-enable recording whenever buffer size is changed.

Good detective work guys. Thanks!
