MP3Gain Giving Wrong Results

Hi All,

I have been struggling over the past few days to get MP3Gain to work correctly, I have not changed any settings and just run it on my mp3's to normalise the volumes to 89db, half of my mp3's look ok when MP3gain is re-run but half of them indicate wacky hi and low DB's 45db and 105db at the extremes. Can anyone shed light on what I'm doing wrong please. thanks.  :(

Or as an alternative, is there a plugin I can use LIVE that will normalise my mp3's as I play them on air.

Thanks.

I'm inclined to think mp3gain 125 isn't working properly it hasn't been updated since 2007, on widows 11 its refusing to volume level a lot of files
AMD A8-9600
8GB RAM
Windows 10/11
RadioDJ 2045
MariaDB 11.2

Hi Davetherave, thanks for replying, yeah it seems to have done 15k out of 35k correctly and totally mucked up the Db level on the rest. Im running windows 7. It looks and acts like its doing the job but on reloading the files they are all over the place... most strange. OK so it looks like I have to go in search of another way to do the same thing as MP3Gain was supposed to do.

The only thing I am annoyed about is that it takes hours and hours to run and then the results are wrong.

Cheers, Thank you for your input.

Look at mp3 gain and you will see that this program does everything in increments of 3 db, which is a lot, no wonder things go wrong.
I use the Adobe Audition Loudness settings in batch for this.

ITU-R BS 1770-3 loudness
-14 LUFS
2 LU
-2 dBTP
RDJ 2.0.3.9

Thanks mebo870, I was looking for a solution more affordable. it seems to do the job though. maybe I will have to take the plunge and subscribe.

Cheers.  :cool:

After much experimentation I found that if I normalised my mp3's in smaller batches then things went without a hitch.

Im using windows 7 and 32gb ram.

Its a shame that MP3Gain behaves like this for me but I guess 32,000+ of audio files is just too much for it. I think it may have a memory leak as I noticed that my ram filled up and then the program crashed, it could be how I have my PC setup of course... Who Knows.

Anyway...All done now.

Geeez! 32,000 files! ???  I'm sure when Mp3gain was created 20 years ago, no one had any concept to process that many files at once. Unless you were a wild Napster head.  :D

Good idea to break up the processing into smaller batches!. The Mp3Gain support forum describes some of these issues, https://sourceforge.net/p/mp3gain/discussion/

Sincere thanks for the link and for your input, I should have checked the online help before moaning about it not working as it does suggest working in smaller batches. DUH! I can be so thick sometimes!

Many Thanks my friend.

I would also think that I may only use a small percentage of my MP3 collection and after removing duplicates I am left with 34,637 MP3's if I use 20% of them on a regular basis that may be about it...we will see.
