I sound design using a large bank of SFX that I continue to add to and manage in Soundminer. I know these sounds very well.
I tag the sounds into Pro Tools when designing in my time-line from Soundminer. In my sound design/editing process I set levels, process sounds further using FX plug-ins, time compress, pitch shift, etc....I know what these sections sound like in great detail before I move forward in the timeline. Then upon playback when mixing stems on my mix pass, I get occasional white noise blasts for the exact duration of some of these imported sound regions (I can even solo and isolate the source of the noise.). At first I would go back and replace quickly and then I realized the error was not consistent with the quality of the parent files. In other words, the parent files in the specific session to which these regions refer did not contain the error.
The only solution I have found to said issue is to quit Pro Tools (Let it think about what it has done.) and reboot. Then playback is then smooth and these white noise errors cease. Any clues as to the culprit? I have had no DAE errors and my computers CPU usage is not maxing out.
It only happens occasionally, but it really freaks out this one client....
