I'd love a program to "normalize" everything automatically, on the fly. Audacity has the facility to do so, but that is a tack by track process, so would be time consuming if you have LOTS of music.
I have almost 1000 music videos that I have downloaded over time. Sometimes I like to load them up to play randomly but I am finding that they all have differing volumes. Some can be too quiet and others very loud. I need to somehow load them into a programme that will re encode all of them so their volume is all the same. preferably, batch style rather than individually. I find myself consistently returning to the PC to turn it up and down which is ruining the experience. Ideally it could be in the player where it will automatically playback at a set DB but to be able to re encode the source file would allow greater flexibility with the ability to use any playback software.

I'm out of my mind, but feel free to leave a message...
All I can think of, for music videos that is, is to transcode the files using Avidemux and apply the audio normalization filter to the process ; avidemux can be driven by CLI which allows you automate the file processing somewhat
edit: For realtime playback normalization, try this -> (link is dead but config is there)

I use Jukebox Jockey to play my video and audio files. It has equalisation built in. I use it on a dual screen system, large screen for video clips and small touch screen monitor for track selection.
Don't worry, it only seems kinky the first time.
For just consistent audio level playback (using original files), VLC can do that ->

Mp3Gain is probably the easiest way to successfully normalise volumes across multiple mp3 files, it will adjust music files so the volume level of each file sounds the same to our ears.
Most of the others will normalise but only on a per-track basis.
If you have one loud song and one quiet song with most software the individual tracks themselves will be normalised, but there will still be a difference in volume between the loud and quiet songs.
Mp3gain solves this by increasing/reducing the volume of songs to a set value in db so to us they sound like they are all at the same volume.
It's not 100% perfect but does a pretty good job, I've been using it for many years now.
gom player has a compressor that can normalise your audio while playing.
Gomplayer also has a bit of a checkered/nefarious rep for installing malware as well -- be careful out there
There's several audio software programs available that can normalise entire folders, but I haven't seen one that can normalise batch-file audio which is part of a video, which is what the OP is asking for.
A bit of info on the format of the files might be useful.
I'm guessing they're .mp4 files?
If so then the audio is most likely AAC, this will probably do the job though I've never tried it -
On the I linked to above there's instructions for using aacgain as a part of mp3gain to normalise the audio of .mp4 files.
As I posted previously, avidemux can do all of this (I had to do it years back to normalize volume of a directory of .mp3 files) Also handy to reprocess (transcode) videos into the container/format of your preference.
