The VideoLAN Forums

Hi everyone, I hope I'm in the right section

I noticed that the volume sometimes jumps when playing videos. In one video it always happens precisely at a scene change, the background music suddenly becomes louder than before, which doesn't happen at all if I use another video player or watch the same scene on my phone. Therefore I think the problem is somewhere in the VLC settings, but I use Windows 10 for the record.
What could influence the volume at specific points of a video? Reverting the settings to default didn't help, which worries me a bit.
Does anyone have an idea how to fix this?

Thanks a lot!

Look in the preferences => audio where you find (among other things) "peak protection" which is actually enabled by defaut (I believe).

Also in the preferences => Input/codecs => Audio codecs and here in both A/52 or DCA you have "dynamique range compression" (reduction of loud audio and increase of low audio) but I believe this is not enabled by defaut.

The dynamic range compression was actually enabled by default, but neither disabling this or peak protection changed anything. Thanks for the tips though!

For the record, I realised I was having similar strange compression effects (on audio tracks between loud and quiet parts), and disabling Dynamic Range Compression in both A/52 and DCA seemed to be what fixed it - but it didn't work immediately, only after restarting VLC.

Hi,
I have the same issues both in VLC Player for Windows AND for Android since updating to the respective newest version (2.2.4 Win, 1.9..?? via f-droid-store on android)

Sound in VIDEOS (xvid, avi, mpeg, flv, everything) becomes low and loud - changing when there was a low soundlevel-scene, it's very low. as soon the scene becomes loud again, it gets louder...
Audio (mp3, ogg) works fine, without the changing volume...

I changed the Peak-Protection-Settings, but didn't work.

VLC for Windows shows the same error on two PC: one based on a Asus P7P55D, the newer on a Gigabyte Z97m-D3h, both on Windows 7.
VLC for Android runs on a Samsung Galaxy Tab 8 running an inofficial CM13-Mod.

Error occured on the Windows-Systems after the Updates to 2.2.4, not sure when it happened on Android (haven't seen Vids for some weeks on the Tab)

Checking with Windows MediaPlayer, the Problem didn't occur - so I do believe it is based on VLC...

Does anybody have an idea what to try? (no sound-effects aso enabled in VLC, intalled the 2.2.4 by "keeping old settings")
