I'm trying to set the compressor and normalizer so that when I open different video files from different sources the volume level ends up being roughly the same.

Also, I have no idea what the "RMS/peak" and "Knee radius" settings do.

Please help!

Yeah, I already looked there.

The problem I'm still having is keeping every video played at the same level, particularly some videos end up louder.

Thanks for your reply. To confirm, some videos end up louder even after you have set up VLC to "normalize" the volume per the post below?

I am not a developer, so I unfortunately cannot provide a purely technical answer here. It does seem that there are still significant limitations to VLC's capabilities in this area.
Plus, audio mastering varies so widely that--at least as a non-developer--it would seem to me that this problem will always persist in some form.
Any additional details you could provide about your user specific scenario would be helpful. I will see what I can find with my limited expertise.

Are you constantly adjusting the volume in movies? Music, explosions, gunshots, etc. too loud? Conversations too quiet? If this is your problem, read on. I am combining information found in multiple threads for convenience.

Navigate to Tools>Preferences. Select Audio. Check the "Normalize volume to:" box and set the value to 1.6
Now switch to Advanced view by selecting "All" in the "Show Settings" box at the bottom left
Expand "Audio" and highlight "Filters". Check the "Volume Normalizer" box. You should see "normvol" added to the text box at the bottom
Expand "Filters" and highlight "Volume Normalizer". Set "Number of audio buffers" to 10 and "Maximal volume level" to 1.6
Hit the "Save" button at the bottom
Restart VLC, as settings are not applied until restart. As I did this in increments, you may have to apply one step, save, and restart VLC between for menu options to be present. I haven't tested applying all settings at once, but I believe you can do this all at once.
Double-check all settings are correct after VLC is restarted.

I hope this helps.

Yes, I already set the Normalizer.

I've been futzing more with the Compressor settings and that seems to help. I kind of figured out what the RMS and Knee settings are, but I still don't know how to change them to get the effects I want.
