How to enable Old Equalization Plugin on 3.3.3

[Trebor]

I am missing the the Equalization effect plugin … When I attempt to enable Equalization it does not work …

If the equalization plugin is 32-bit it will only work on a 32-bit version of Audacity.
The latest version of Audacity is available in 64 & 32 bit, (32-bit Audacity will run on 64-bit Windows).

If you need a free 64-bit equalizer plugin for Audacity, the ToneBoosters V3 are good …

Free (v3) ToneBooster's plugins

https://www.toneboosters.com/support.html click on “Where can I find older (legacy v3) plugins ?”. Many are improved versions of Jeroen Breebaart plugins, (32-bit Windows only), but these (v3) are 64-bit versions, Windows & Mac. DeEssers, compressors, equalizers, limiters, tape emulation, device/room emulation, bit-crush, gate, reverb, chorus, delay … IMO well worth the effort of download.
