I'm using Garageband v 5.1, with Addictive Drums for drums; here's the process I got through with the drums: Create an Addictive Drums software track [MIDI], program the track, and then export MIDI track to iTunes to create an audio file. Import the created audio file, mix said audio file. Once I've mixed this audio file and exported the audio track to iTunes, the volume is wrong: with normalization [Garageband auto-normalizes it], it's too quiet; without normalization, the volume is fine, but it's "crunchy", and the quality is horrible. Here's how I mix the audio drums file: divide cymbal, snare, and kick audio files into separate tracks, adjust the EQ of each track [kicks and snares give the most trouble], limit each track, etc. I've tried compressing and not compressing, limiting and not limiting, equalizing and not equalizing; I've tried every combination of mixing techniques I can think of, and I'm really out of ideas. I've read online articles, and tried to apply what I've understood [I'm sure I've missed some technical stuff], but nothing has worked. The worst part is, I can record and mix the songs within the DAW; there's no quality loss prior to exporting the audio. I can hear the finished song, but I can never finish the song. If anyone has any advice, I'd really appreciate it, because this inability to record anything will eventually kill my desire to have anything to do with music.
