Audio normalization(?) for mp3 files

Let's start this right: I AM NOT A TECH. Let me repeat that: I AM NOT A TECH.

I have a batch of files that have 50 or so mp3 music files in each file.

The mp3s come from different sources, and were obviously recorded at  different levels.  If you were listening to one file of say, a dozen mp3s (songs), you might need to turn the volume up or down for various ones.

By the way, did I mention that I am NOT a tech?

What I'd like to do is to adjust the levels of all the mp3s in all the files so they're all about the same, eliminating the need to "turn the volume up--or down." I'd like to do this using software that can do the adjusting for all songs in one file in "a batch" so that I do not have to do each one individually.

And in case i didn't mention it, I am not a tech!

I have done a lot of online reading about audio equalization and normalization and have come away without any real understanding because---can you guess?--I AM NOT A TECH.

The only thing that made a LITTLE sense was that MAYBE MP3 gain was what I should use. But I'm not sure.

So here I am, hoping that an expert who can explain something to someone who is NOT A TECH in plain English, will help me out.

Any takers?

It's really simple: download, install it, run it, add all the mp3 files into the software, set the gain level, then hit Track Gain to normalize, done.

Wayne, a question inspired by your comment: in MP3 Gain, the default "Normal" Volume is set to 89.0. How should I determine what the BEST volume level is to set as a default? We're talking over 60 files, each of which contains an average of 40-50 songs.
Hi RadioGeorge,

I like mine a little louder than that, I normally set it to 91 because most of the audio mp3 files I needed to normalize were actually seminar audios.  They are terrible because sometime the speaker spoke loudly, other times they are a little low in volume.

The best default gain volume will vary from listener to listener.  I would recommend you to find an mp3 file that "fits" your ears then determine the gain level on that file and use it as the default gain level for normalizing.

Here is another video that may help you.  MP3GAin finding volume of your MP3 files:

Wayne, the videos (plus one other listed among them on the YouTube page where these are) helped to explain a lot. I do have one other question as a result of our exchanges here, before I wrap this posting up.

I found a program called GoldWave ( that appears to be similar to MP3 Gain. Could you take a look at it, and tell me how you think it compares and stacks up to MP3 Gain--easier, more difficult, pretty much the same, or what?

Hi RadioGeorge,

I've used that software in the past as well.  GoldWave is a good software that does more than adjust MP3Gain.  I've used GoldWave mainly to edit MP3s. Cutting, and fading the end of abruptly ended MP3 and it can also do batch normalizing of MP3s.  

However, for your purpose I recommended MP3Gain because if all you wanted was to batch normalize MP3s it's very easy to use and it's free.

Hope that helps.

Short, sweet, to the point, comprehensible, and with videos to make sure all is explained in detail.

Can it get any better than that?

Thanks, Wayne!
Glad to be a help RadioGeorge.  Cheers!
