Occasional mis-sample on print track
 

Our studio uses a print track internally within our Pro Tools sessions so that we can QC our mixes in real time before client delivery.

Recently, we have noticed our prints creating a “blip” right at the end of spots. This happens inconsistently and fairly infrequently, but it is enough that our clients have noticed and reported the issue to us.

In the last one or two samples of a selected region to be printed, the print track will randomly pull audio from earlier in our spot, despite every track being routed into the print being completely faded out by this point. I am completely sure there are no other hidden tracks causing this final blip, especially because the issue can be solved by changing nothing within the session and simply printing the same region again, non-destructively even.

Has anyone experienced this before?

I can grab some screenshots if that would help anyone understand better.

Have you done the usual prefs and databases trashing?

Are you printing real time? Or offline and importing to the tracks? I almost always do it offline now and place onto the print tracks for playback. I have not had this issue.

If it's real time do you have any post-roll?

is there a master fader with a hard fade to zero at the end of the region?
if not, I would try that

My suggestion as well, or if you can pin it to a certain track, fade that one. Where I have seen this is when my master track fades out, but snaps back slightly before the actual end of the bounce, causing a reverb tail to jump back in. If the fade out stays out for an extra second or two, that usually solves it.

Alternately, if you're going to export your print, put a short fade at the end(or beginning) and consolidate before the export.:o
