I recently discovered a wonderful plugin for Winamp, called "Volume Logic" : Unfortunately, this is a commercial software, and it doesn't exist for VLC.
The problem : When I'm watching movies on my vlc 0.8.2, the music is often louder (too loud...) than the talks :
While I was listening music with winamp, some tracks were just "more loudly" recorded, so that I had to increase or decrease the volume after each song : With "Volume Logic", the sound is automatically adjusted : I have absolutly no technical backgroud, but I thougt it could work the same way...
So, I was just submitting you the idea to integrate such a feature, don"t really know how busy you are...
Bye
