hi Durin interesting... It seems to me that as I lower the playback resolution of the video window in Audition, I get smoother playback. But it's still not at all what I would expect, and without fail within a few seconds I see dropped samples (even at 1/8 resolution). I'm still get dropped samples with the video window closed, but the software is noticeably more responsive. Today I have been migrating the dynamically linked multitrack session to a new session - the primary reason being I need to work on a 5.1 mix now that the sound edit is complete. Since my Premiere Pro timelines have stereo masters, the Audition sessions created when I send from Premiere are also stereo, so I've created a new multitrack session in Audition with a 5.1 master to do my surround mix, and I've exported an H.264 from my original (Pro Res 422) timeline in Premiere. I'm currently populating the session with the audio exported from my stereo session (the dynamically linked session I did the edit in) and I'm up to 60-odd tracks with no dropped samples. - I'm keeping an eye on this as I add more tracks, automation, and ultimately some mastering effects (plug-ins), so we'll see. "Looking at your session screenshot, while there are a lot of individual tracks, there's not that much content." Exactly. Lots of tracks, but rarely more than 6 at any one time in that session. I have some plug-ins on some tracks now, and some are a little CPU intensive but the tracks are all pre-rendered. However the problems started before I even had those plug-ins in place, and weirdly even muting tracks that did have plug-ins (and I thought could have been the problem) didn't reduce the jittering audio playback. Honestly I've worked both in Audition and in Logic Pro many, many times with more tracks and more plug-ins than this (and on slower machines) before having problems with audio playback. It doesn't seem to me I'm asking the software to do an awful lot.
