I host a “how-to” podcast about podcasting and using Audacity and would highly recommend Chris’s Dynamic Compressor for podcasters and other Audacity users.
In Chris’s memory, and with his dad’s help, I am hosting Chris’s Dynamic Compressor on my own site. I found a bug in the 1.2.7 beta, so I’m currently offering just 1.2.6, but I keep a copy of 1.2.7 also on my server.
