Something weird at the Circle K

[jkess]

My PT rig is doing some weird stuff. Anyone experience bizarre audio shifting (on the order of a few bars later in the song approximately)? The waveform doesn't move, its just being played back later. That is, I printed a song, listened back and a few tracks were playing back in totally different places. By simply rebooting the computer all was fine - without touching any of the tracks.

Also, there seems to be occasional strangeness when using the F6 tool to reveal audio. All of these issues seem to be when I am mixing and the processing load gets very heavy. It's not when I am in the early stages of a song. I typically run at 96khz which could be taxing the system and bringing about processing issues. An engineer who also works here noted the same things and said he also gets some occasional snapping or popping sounds while the system is operating with a very heavy workload. Any of this sound familiar to anyone?

Thank you kindly.

Hi,

Well you've really answered your own question! when the CPU is near max you can get pops and clicks and also what you experienced when you bounced to disk and listened back and stuff was shifting! you can use RTD (record to disk) as apposed to BTD (bounce to disk) by bussing your mix to another track and recording it onto this track! this might ease your problem when bouncing.

You can try making your HW buffer bigger in the playback engine, this will give you more CPU and might be enough to stop the problem!

Also in the playback engine there's a tick box for "RTAS engine" ignore errors during playback" if this is ticked you won't receive watnings from PT that your system is overloading but instead you will just hear the results of it overloading!

I have experienced something similar several times on a LE PC system. In this case the audio plays back in perfect sync but the waveform is late (by up to about a bar).
