I used to use Audacity like 20 years ago, lol, so I can't speak to what it can do these days, I am an old sound engineer certified in Logic Pro X and proficient using Pro Tools, Ableton, Cuebase, etc, and building tools I use myself. So yeah, give them a try. For automated tools, they are pretty good if I don't say so myself. I had 2 other engineers work with me on the mastering tool alone.
