Music sound level equalizer / control

[AllAmericanJock]

Does anyone know how to control the volume level of the music. Some music volumes are higher than other music. Some of the music is hard to hear, while others are too loud. The speaker I am using is Yorkville Coliseum C120P. Any suggestions or ideas would be great appreciated.

The first thing you need to do is look at the bit rate of each mp3 file. If you even out the bit rate at the LOR recommended 128 kbps that usually evens out the volume. You can modify music using Audacity:

You can also use MP3Gain to level out all your music so some music isn't louder then others:
