Hi all; I've decided to try out MP3Gain, but one of my main concerns is: if I don't like how they come out, can I "undo" what I've done? In reading the Help file, I noted this:



If I'm interpreting this correctly, if I process a folder with 600 songs in it, I'ld have to write down the names of each song and its associated "volume" level in order to manually set each one back. Not a very realistic way of doing things. I also assume, that the programs built in undo function is only good for a particular session. In other words, if I listen to the mp3's for a few days, I couldn't reopen the program and undo what I've done.

Can anyone confirm that I'm interpreting this correctly.

And one more question: ultimately, my goal is to make all my mp3's play at the same relative volume. But it seems impractical to try to process 20 Gb's of mp3's all at once. If I leave the Target "Normal" Volume setting the same, can I process all the mp3's in groups? Will all the groups be adjusted to each other, or only within a group?

Thanks all for helping me out here, Dex

The latest version 1.2.1 should have full undo functionality. I haven't tried it yet myself but as I understand it it should be able to undo at any time. The undo data is stored in a tag that is attached to the file, so as long as you don't remove that tag it should be possible to restore the orghinal volume. So beware of tagging software that might remove tags...


Yes


Each song (if you use track gain) or album (if you use album gain) will be adjusted to the target volume you specify. They (songs or albums) are not adjusted to eachother, but to the reference target volume. So as long as you don't change the target volume you will always get MP3:s at the same volume.

Hi magic75; Your comments seem to be right on the mark. Although, now that I've tried the program, the question of "undo" seems purely academic. MP3Gain works great! I can't imagine any reason to undo what it does.

I can't believe it took me this long to try this program out.

The only "oddity" I notice is, it does tend to make all the songs somewhat quieter than they were before. I imagine this probably isn't a problem as long as my signal-to-noise ratio remains acceptable. (Which it appears to so far.)

Thanks again, Dex

i want to mp3gain my music directory full of albums and singles via command line. would this be the best way to go about it?



help me out if this is wrong guys... thanks

Just curious, where did you find this quote? I just read through the entire help file, and checked the website, and saw nothing anywhere about command line options or functionality.

i just know that sweep allows you to move from directory to directory without having to type them in, i got it from the mpcgain thread

Well, I guess you have kept the target volume at its default 89 dB, right? Then it is quite natural that they sound considerably quiter than before. Most modern music today is mastered to CD at volumes like 95-99 dB. The point of using 89 dB is that you are almost certain that you won't have problems with clipping when the file is decoded.

Yup . . . been there, read that, its what inspired me to try MP3Gain in the first place.

Probably shouldn't have refered to it as an "oddity".
