Compressor

I can’t compress my audio at the moment. I can use noise reduction, but not the compressor.

More information required. Please read this: https://forum.audacityteam.org/t/how-to-post-a-question-on-the-forum/23175/1

I’m using Audacity 2.2

Audacity versions go by three numbers, not two. If you have a two number Audacity, it may be a bogus version.

It’s Audacity 2.2.2
