Garageband does not have a master balance (left/right) control. You will have to adjust the pan control for each track individually to balance the sound left/right.
Garageband is a mult-track audio, sound loop and MIDI instrument song creation tool.
The track editor is used to make changes, or add effects to a track in your garageband project.
Unprotected songs can be dragged into the Garageband window where they are added as a single track. It is impossible to split the song down into its individual tracks.
Have iTunes and GarageBand open simultaneously. Drag the songs you want into garageband and edit as you'd like. When you are finished click on share from the menu up top and select "Send Song to iTunes."
Watching the levels for each track in GarageBand helps ensure that the audio signal is not too loud (distorting) or too soft (indecipherable). Properly monitoring levels can help you achieve a balanced mix, prevent clipping, and maintain audio quality throughout your project.
The G3 iMacs were discontinued in 2003 and Garageband was not launched until 2004 so they would not normally have had Garageband installed. If an early version has been installed on a G3 iMac it will be of limited use as Garageband requires considerable processor power to handle multi-track compositions for which the G3 processor would not be suited.
Import it into garageband, then click 'Track' at the top, then 'Hide movie track'. Then export the song to iTunes.
