How to adjust .mkv files audio volume level

audiolosslessmatroska

I have a bunch of .mkv video files which audio is REALLY low volume.

How can i adjust the volume higher permanently in the .mkv file? preferrably with lossless methods (if even possible?).

Yes, i know i could just turn my speakers full volume, but then again if i watch some other video with normal sound levels, then my speakers would kill me!

Mkv is a container format that can hold almost any video or audio codec. You would need to figure out which audio codec(s) is/are being used in your files and see if any kind of lossless volume adjustment tool exists for that codec.

It isn't very well documented, but FFmpeg has a -vol switch which will allow you to increase volume output.

Example:

ffmpeg -i vid.mkv -vol 512 -vcodec copy output.mkv

Some things to take note of:

the -vol switch uses "byte percent", so you can't just specify a 200% volume increase, 100% = 256 so specifying 256 would leave the volume as is, 512 would double it and so on.

Windows – Normalize volume of all the computer hardware and software

This is an old post, but I found a proper solution for those with Windows:

Under Control Panel > Hardware and Sound > Sound, right click your audio device, select properties > Enhancements, then turn on the option "Loudness Equalization".

You can also change the release time by clicking "Settings" inside the properties > Enhancements tab:

The release times determines how long the computer waits before raising a quiet sound, or lowering a loud sound. The shortest setting is instantaneous, while the longest takes one minute before the computer adjusts the volume.
