I'm often victim to some loud sound playing on my computer all of a sudden when I have my volume level turned up already to watch a quiet video. I can't turn everything down to the level of the quietest video I will ever watch; that's impractical. I can't even control the volume level of some applications.
Is there an audio proxy or some other plugin that can limit how loudly a sound will be outputted from my built-in audio card? I'd like an audio output level limit control in addition to the system volume control. For example, if I have my volume up all the way to watch a quiet video, any loud sound that plays should sound as if my volume is set to half or something. I've got my Mac connected to external speakers with an analog 1/8" cable.
