Free Plugins that will work with Audacity?

I'm not sure what version you have, or what version is the most current....I just downloaded v.96 and there doesn't seem to be any provision for using 3rd party plug ins. I use Nero Wave Editor 2 which comes bundled with Nero Ultra 6, and it supports most plugs I use with Sonar (Dx and VST). The ony downside with Nero is it only supports 16 bit files, so not great as a mastering platform. I also use Acoustica, which supports 24 bit files and only costs $29, but it doesn't support all the plug ins that Nero does (only VST I think). Acoustica might be an option for you. Good luck.
