You're looking for a multi-band compressor. A multi-band compressor is not an effect that is standard in the Audacity plug-ins folder.

However, you can select any 32 bit multi-compressor VST plug-in you may have on hand.

In Audacity go to "Effect" > "Add / Remove Plug-ins ...". When the Window opens select (1) Show: All, (2) Enable and (3) OK to add the effect to the effect drop down list.

Audacity is a 32 bit program. I don't know if you can use a 64 bit effect but I don't think so. I have jBridge but none of my 64 bit plug-ins show up on my list
