Probably a lot of the problem GP is describing comes from people having inconsistent distance to their microphone, moving around a lot. Then using an audio compressor effect plugin is an appropriate answer.

I've often thought about adding a compressor pedal to my TV sound system. It would be excellent for when you're watching action movies with hard to hear dialogue mixed with loud noises, and the kids are asleep, so you spend the evening turning volume up and down eight times per minute.
