Does anyone have a suggestion on how I can lower the volume on WAV music that I use in a slide show? Would you have any suggestions for a free or very inexpensive program to decrease the volume on the music file instead of lowering the computer's volume. I would like a very quiet background music when the autoload starts playing without adjusting the computer volume.

Right now I use Wavosauras to edit my music length but don't know how to decrease the volume.
