intermittent background noise

learn some audio engineering

There isn’t a lot. I had to get techie when I listed the numbers you have to type into the blank boxes when you run the tools.

And given you record in a nice, quiet room, there are only three tools. Rumble filter, general volume and overload safety. I wrote a mostly English explanation of what they are.

Further, the values stick, so you only have to type them once.

I’m not the only one. There was a poster recently using different spells, and they managed to pass submission after minor adjustments.
