I think you’ve been here already, right?

This might wait for a Windows elf.

there is however a Leveller

There is a reason Leveller show up under Distortion Effects. Other tools and processes sound much better and the developers were going to shovel Leveller out the door, but we said there was no better way to get Taxicab Voice, 2-way Radio Voice or Air Traffic Controller Voice distortion.

If you’re getting desirable work with it, then you should keep using it, but just know that it’s an older, brute-force tool that intentionally creates distortion to get it’s job done.
