See from 2:50-4:18

If so can you point me to a tutorial. Thank you!

I know some people use vocal riders but this seems to be the most effective method.

If you change your mouse tool to the pen tool on an audio clip you can adjust the gain. Also now in vari audio 3 you can adjust the volume of each segment as well.
