Anyone know of an Audio Plugin For Avid To Remove Ambient Sound?

iZotope RX's Voice Denoise and Dialogue Isolate. Accusonus have a Noise Remover. Waves have various denoisers. There are probably more.

iZotope is my go-to plug-in for cleaning up sound. I went for their Post Production Suite bundle, but Voice Denoise is included in their Elements bundle.

The ultimate is Cédar, but that one's expensive.
