I spent a few minutes playing with the volume level of each track (there are three) until I felt the vocals were louder than the other two tracks, but when I uploaded the track, it seemed like those adjustments didn't translate.

GarageBand is a Mac program that comes with their computers. The purpose of it is as a tool for musicians to create music. While this track was made using canned loops which come with the software paired with the Librivox recording, I've also been experimenting with recording myself playing guitar and bass through amplifiers and plugging them directly into my laptop. So far, it's proved to be the most versatile and most user friendly recording software I've ever used.

Several popular musicians use the program; off the top of my head I remember John Mayer and Macklemore being users. I would recommend it to anyone interested in such things.
