So after this conversation I decided to go check and see if there had been
improvements in the noise reduction in Audacity. There has been, and
fairly significant, at least it is usable now for certain materials, but it
still doesn't hold much against other solutions out there. Granted I only
checked with a boom recording from a shoot I did a little bit back, but yes
there are definitely still artifacts there, and possibly worse is a
reduction(Not huge, but noticable) of consonant sounds reducing
intelligibility slightly, especially on quieter parts.
Still overall much better than it used to be, and if I needed to do a quick
cleanup I might consider it now at least, that is a huge step from where it
was. But my preferred method is still using some proprietary plugins I own
