I'm constantly working with audio and video files that have very different volume levels. If I have my speakers at 2% with one of my LBT tv series, it is so loud that the house shakes. Then, I have to have the level at 30% when working with things such as vocal removal (which I do quite freqently). I might think that the speakers are at a very low level and shut down the computer and get blasted. That happened once. It vibraded like when a jet plane went by and I couldn't hear too well for a couple hours after that. Luckily, I was home alone at the time.
