Adaptive Noise Reduction - Mic 'robotic' distortion

So I have my mic set up to utilize the 'Adaptive Noise Reduction' effect to cut out excess background noise, and for the most part, it works like a charm.

The way I have it set up is I have Audition open and in the Audio Hardware settings, I run my microphone in through the "Default Input". I then have the "Adaptive Noise Reduction" with latency at 50 ms which cancels out any excess background noise. Finally, for my default output, I have "Audio Virtual Cable" so that way it takes the filtered audio from Audition and uses it in Discord or OBS or any application that I'm speaking into (I set the default microphone for those applications to "Audio Virtual Cable").

Unfortunately, every so often, people I'm talking to tell me that I've "gone robotic" - aka, the mic becomes extremely choppy. Here's an example of this:

At the beginning, everything is working fine with Audition filtering out background noise and my voice coming through clear as day. At the :28 second mark until the end, however, it gets extremely choppy and distorted and there's nothing I can do to fix it other than wait for it to go away. It usually clears up in around a minute by itself.

Does anyone know the cause for this, and if so, how can I fix it?

Much appreciated!

    Yes - that's the only one you can alter!

    That sounds remarkably like a buffer overload (where it empties before it can be sufficiently re-filled). Something else is using up resources in your PC, at least temporarily. If it is, and you aren't monitoring directly what's coming out of the processing, then the easy answer is to increase your sound device latency, which makes the buffer bigger, so it doesn't run out.

    There are any number of possibilities as to what might be taking over resources, but ultimately the solution is to monitor the processes in your computer to see if you can find anything which correlates to this happening.

    By increase the sound device latency, are you referring to the latency setting within Audition?
