I play my MP3s over a cheap stereo. Some MP3s are not loud enough.

Is there some a software program that makes it easy to increase the volume by, say, 10dbs?

If you want to do this non-destructively (ie don't increase the volume in the file as some fidelity will be lost), you can set your EQ to +10db across the board in your media player.

Holy cow. I didn't even realize that this setting existed. My MP3 can only do +3db but that is enough.... thanks for the tip. – user1413 Feb 28 '10 at 13:54

The esiest way is to install MP3Gain and use that.

Tired of reaching for your volume knob every time your mp3 player changes to a new song? MP3Gain analyzes and adjusts mp3 files so that they have the same volume.

MP3Gain does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear. Also, the changes MP3Gain makes are completely lossless. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding.
