Audio Dropouts: Adobe Audition 2019/Windows 10/Audient ID 14 Interface.

What do you have the buffer size set to? Also, it's worth noting that if this happens at some times and not others, it is almost certainly a background process happening in your PC that's causing it by effectively stealing processing power from Audition. Typical culprits here are Wifi searching and anti-virus software doing scans, but it's also possible that the OS is doing awkward things like altering the size of temp files. If you look around, you'll find that there are sites that will tell you how to optimise your PC for audio recording, and it's well worth taking the steps they give you - things generally improve significantly after you've curtailed Microsoft's attempts to stop you using your machine the way you want to!
