FFmpeg on its own can't do it. At the moment, there is no audio filter that performs normalization. You will have to export the audio stream, normalize it, and sync it back into the video container.
Step 0: Find out if you want to normalize
This is not necessary, but you can analyze the audio stream for the maximum volume to see if normalizing would even ...

I end up getting a lot of documents that are a complete mess and impossible to maintain that I need to clean up.
You'll want to learn and use paragraph/character styles if you're not already using them.
In the home tab of the Ribbon, look for the "Styles" window.
Selecting a paragraph or multiple paragraphs in Word and then selecting one of the Paragraph ...

Checkout the appropriately named Normalize:
Normalize is a tool for adjusting the volume of audio files to a standard level. This is useful for things like creating mixed CD's and mp3 collections, where different recording levels on different albums can cause the volume to vary greatly from song to song.
It works for all types of file formats, ...

Edit 1:
I should mention that the tools I list below are not actually normalization tools, per se. They are tools for applying the replaygain algorithm to determine the music file's loudness and add a tag to the file indicating the relative loudness. The critical difference is that normalization actually involves re-encoding the audio data, whereas ...

Normalization vs. compression
Normalization is not what you're trying to achieve. If you say that the video track has different volume levels, normalization will maximize the general amplitude of all parts at the same time, so that the loudest part (the peak) goes to 0dB or less, depending on the implementation. That means the loudness difference between ...

The only way I know of:
Use the Virtual Audio Cable to loop back the sound into a sound processing server, like VSTHost or Console. Load a VST Plugin into VSTHost that implements a compressor/limiter. Set the output of VSTHost to your real soundcard.
Some of it is described here.
The compressor will increase the sound level of the quiet parts of hulu, but ...

Normalization will only move the audio up to the point where there is no distortion.You will probably want to "squash" the audio using dynamic audio compression and then increase the gain. Compression isn't really lossless in the sense that you are changing the audio and ultimately the dynamics.
A compressor is a tool that engages at a certain audio level ...

You can use Audacity to normalise channel volumes. I'm using an old copy of Audacity 1.3.13, which is a beta version, but just about any version should have these options - some plugins may have to be installed, but they're easy enough to find.
Load/Open the audio file. You should see two channels, since it should be a stereo file. There may not be a ...

Excel has a built in Transpose function that will switch row and columns but that won't work for your scenario. The only that I think will work is a VBA function. My VB is a little rusty but this one should work. You will need to modify the "A1:E5" range to cover the cells you want transform. And this copies the values from the first worksheet named "Sheet1" ...

Its not really possible, although you can do some things to mitigate the problem.
For a start, if the sounds comes out of your computer in analog form to your speakers/headphones etc, there's no way to somehow sync the physical volume control on the speakers back to the PC etc.
As your speakers/headphones are the last device in the chain to your ears, that ...

The issue is that not all audio is created equal on YouTube or other video sharing sites. It really is the job of the video creator to normalize the sound before it gets uploaded to YouTube. That job is done through compressors, limiters and audio gain.
Theoretically, I guess, you can create a program that listens to the master audio out and applies the ...

No, because the point of MP3gain is to physically (and reversibly) alter the actual mp3 files so that they can be played without having to have an mp3 player that knows about the ReplayGain tag that foobar2000 (and many other media players) can use to change the music volume on the fly.
MP3Gain is most useful when used with cheap mp3 players that have no ...

You can use the command: mp3gain -c -p -s i sochi.mp3
The flag -s i will write album and track replaygain values into the id3 tags, but won't change the gain of the mp3 file. Software that handles replaygain will play the song at the adjusted volume, but software that does not will play it at the original volume.
As long as you don't use the flags -r, -a, ...

How about the "Sound Check" feature in iTunes?
If you already have Sound Check on, there's a possibility that your iPod is applying old (pre-MP3gain) information to the already-normalized songs.
1
To clarify this (I hope), there are a couple of items at play:
1) The volume level of your MP3s
2) The soundcheck values associated with your MP3s
3) Whether soundcheck is enabled for playback within iTunes and/or playback on the device
If your tracks are in iTunes, and Soundcheck values have been calculated, then, when you play those files in iTunes or on ...

If you are on OSX you can use Soundflower (Audio-Driver), this works for some applications.
One example:
Play a movie with VLC
Set the audio > audiodevice > soundflower (2ch).
This will redirect the sound and you will at first not hear the sound
Open garageband and create a new project
Add a "real instrument"
Set the input in garageband > settings ...

I found this, started out as good news

You could investigate Replay Gain. I've not played with it much, but my understanding is that it scans a file (or directory/album) and adds meta-data to the tags, so that a Replay Gain aware player then adds the required amount of gain during playback to normalise the volume level.
Advantages: no decode/recode process, so faster, and no extra audio ...
