Two “lite” plugins (Mac & PC) from waproduction which offer one-knob multi (4) band compression.
Simple to use & free, so ideal for the novice.

Puncher is less aggressive than KSHMR, (the attack/release are not adjustable in the free lite versions )
I can confirm the 32-bit versions work in Audacity in Windows.
I don’t think the full paid-for versions are worth the money,
but the free “lite” versions are worth the effort of downloading
[ You need to give them a (disposable ) email address ].
The multi-band compressor knob in KSHMR is named “pressure”.
(confusingly there is also a one-band compressor knob, named “comp”).
