Harrison Mixbus daw could be useful, as your sound can be recorded or
imported into that time-tested console environment, with it's own
useful plugins and capabilities. The price is amazingly low
for the potential and tools, and is often on sale.
You can view a track in audacity, import it to mixbus,
export, and visually/sonically compare the two versions.
Then dig in to the details.
IK Multimedia sell T-racks Sunset Sound Studio,
and Lurssen Mastering Console as plugin suites
with similar purpose, that run in modern
wine/reaper, and when wrapped by LinVst,
may also run in Linux Mixbus, worth trying the demos.
You could have three world-class sound facilities
at your fingertips. Youtube has videos.
