Novice question: My mixdown in Adobe Audition is rendered with a clicking out of the right channel. I don't know where it's coming from or how to get rid of it. I suspect it might be something like a computer process or wifi. I've never seen this before and I'm not an audio pro. Any insight will be very appreciated!
Start by eliminating tracks and/or plugins from your mix to see exactly which track is causing the problem. In fact, mute everything entirely and see if the clicking still occurs. You should be consistent with your mix parameters during this process and mix using full-speed offline mixing if that is possible with audition.
Also experiment with buffer size changes at the asio/core-audio level.
I strongly suspect a plugin is doing this, so identify the track containing the suspect plugin then start testing each of the plugins individually and then remove the offending one.
