Just booted it up here - sounds good! I guess you pretty much brought the levels up on everything that was quiet? It sounds like everything is roughly leveled the same, now.
More or less, yes that's what I did. But, unfortunately it's not as simple as just applying a normalize filter...
On some tracks I actually went in and applied EQ's to different parts of the song.
Lots of adjustments per song to try to get the sound I felt was correct....
Anyways, glad you guys like it! Working on another game now! Guess which one.
