I have all new hardware and softward - a Windows 10 laptop PC with Adobe Audition CC - all deployed this year.
When recording - admittedly with multiple windows open on Google Chrome and in Word - my recordings occasionally skip.
More accurately, and when I have the Adobe window open but not on display, the recording inexplicably pauses for a split second. When I go back to listen, the sentence "Mary had a little lamb" may sound like "Mary h/tle lamb." There is a brief instance of an audio spike at, what shall we call it, the stutter.
This happens maybe 20 percent of the time I record, particularly in long form for my podcast recording.
I typically use a sample rate of 44.1k (I have been unable to change the 48k default setting) in mono at a bit depth of 16. I also clean my PC regularly with CCleaner and Revo Uninstaller.
Any ideas on how to cure this?
You haven't really given us too many hardware details like ram, cpu, etc but I would be shutting down all other applications as well as anitvirus software, search indexing, everything that might take away cpu cycles or require hard disk access - basically everything else.
Start with that and see how you go.
I agree - get rid of all the background stuff, especially anything that's likely to try to steal your sound device...
