setting an audio track?

Hey PointCardinal!

You can use Auto-Volume to let Rush pick a good level for your track overall, and you can use Auto Duck to automatically raise and lower the volume in reference to other audio in the project. So if you've got a voiceover that comes in and out over the course of the project, Auto Duck will lower the volume when the VO is talking and raise the volume in the spaces between each VO clip. 

Hope that answers your question!
