I ran into the CEO of Izotope at a conference, and followed up by

plugins in Audacity. Here's a thread of email from their QA guy who ran
some tests, Tedd Terry.

For QA folks, any responses to his questions in the last paragraph?
Probably a good idea for us to do this generally, at least with major

I haven't checked all of our products in Audacity and I didn't poke
around too hard for latency compensation options... Just in the
General and Effects options.
