Audio files with different sound levels.

[BorisTheAnimal]

Basically what my problem is that some mp3 files that I have on my Windows Lumia 720 phone are very low on sound when play them and yeah my question is how can one song be louder than the another?

Uh don't if I posted this in the right sub-forum.

The levels can be different. Depending on who originally recorded it, etc.

I have a recording studio and when I do final mixdown/mastering I also set the level of each song. Thus, for example, all songs on a CD are at the same volume level.

I've seen (heard) a lot of CD's that have songs with different level.

You can run each song through a program such as Audacity and change the level to whatever you want. Audacity is a free and popular recording program. Audacity: Free Audio Editor and Recorder

I see, thanks for the response, I actually have Audacity though never realized you could use it for this.!

You can also try the mp3gain program. Free at no charge here:

MP3Gain

It adds a little bit of info to the mp3 header that tells your playback program to boost or reduce the playback volume so that all files are reasonably close to each other in perceived level.

It's very quick. You can process thousands of files per hour on an ordinary PC. The changes can be undone at any time.

The playback levels are adjusted to be within 1.5 DB of each other--close enough that the average ear isn't going to detect the differences between songs.

It isn't perfect. It samples the volume at dozens of places in a given song and uses those samples as a baseline from which to adjust the entire song.

It may not work for you as I don't know if your playback app on the phone is sophisticated enough to read the instructions sent to it by mp3gain. And you may have to process the files on a PC before moving them to your phone.

I've been using it for 6 or 8 years and am satisfied.

You can choose between "album gain" and "track gain". You'd likely want to use "track gain".

Play with it. It's not going to hurt anything.

I'd try it before Audacity for several reasons:

It's very quick in comparison to Audacity and does not involve a re-encoding, which can reduce mp3 sound quality. Its changes can be undone. It doesn't modify the audio portion of the file--only the header. I'd hate to have to modify even a hundred songs manually with Audacity, which is a great program that I use constantly. It's just time-consuming for this type of job.

As stated, MP3Gain is good if you want to have the same level of mp3 files. Just load the songs, and select "Track Gain". Track gain is good if you download songs from different sources. The default volume is 89.0 db. I also used this program, and I am also satisfied with the results.
