Same sound level on a mix in GarageBand
I am mixing about 100 tracks from a playlist in GarageBand.
The tracks are from various sources, then transferred into iTunes.
As they are from various sources, the volume level differs quite significantly between each track.
When I've mixed the playlist, I want it to play back at the same volume level.
Does GarageBand have a way of ensuring the same volume level across the whole playlist once mixed?
Thank you.
