I was recently using the VSE to put together video to match a narration. The quality of the audio recording was pretty weak (did it with my laptop and a headset in several different places over a couple of days). One thing I noticed was that the volume could vary pretty drastically. I think I was using a volume factor of 4 on a couple of the strips.
Does blender have any ability to graph or otherwise measure the volume to help you balance things out between different audio strips?
