Waves makes a whole suite of programs. They elaborate on all of them at their [a href=www.waves.com]website[/a]. The ones that I've used are the L2 Ultramaximizer, IDR Dither, and the Renaissance Convolution Reverb. I use the L2 for shows where the crowd is much louder than the music and for some stealth shows. I use the dither whenever I go to 16-bit (or as part of the L2 b/c the the plugin is 32-bit and I'd dither back down to 24). I've used the reverb for a very dry-sounding room where I made an onstage tape. I ended up liking the non-reverbed recording better, but it was interesting to compare.
