Auto Noise Gate?

[SabyTheGod]

I was watching a movie, and I noticed that in between conversations, the background audio was shut off, and then resumed as the actor spoke, and then shut off a little while later, to then be activated while the other actor responded. Pretty much like a noise gate effect was on. At first, I thought it was the movie, but I noticed that there were already background sounds (raining, cars passing). Still, I only heard it for the couple seconds that the actors spoke, and it brings me to believe that there is a noise gate because those background sounds are low enough not to activate a standard noise gate that is geared toward dialogue. I haven't messed with many settings other than increasing the file cache. It isn't a big deal, it's more of an annoyance as the "attack" time of it is quite responsive, and as soon as there is no dialogue or a sound enough scene, the complete audio shuts off. Can anyone explain if there is a default noise gate and if you can even disable it?

There is no such feature in VLC, at all. Forget defaults.
