Many people and programs who encode video don’t always respect good practices when it comes to audio volume. There are few things more annoying while running a video playlist than to have to jump out of your chair and crank down the volume because someone didn’t respect decibel limits. Fortunately, VLC includes a live audio normalizer that detects and suppresses sudden jumps in sound. To access it, choose Tools -> Preferences -> Audio.




It’s worth noting that there is a slight delay in the normalizer. If you’re watching a video where a gunfight breaks out, the first shot might be missed by the normalizer but it will kick in shortly after. Also, it seems that if you enable this function while a video is playing, you will need to restart the video for the normalizer to take effect.
