- Step 1
GarageBand does not export every track at once: set the cycle region over the whole song, solo a single track (the headphones icon) and use Share › Export Song to Disk…
Where to export: Share › Export Song to Disk - Step 2
Choose WAV, save the file with the track’s name (drums.wav, bass.wav…) and repeat for every track.
- Step 3
Upload the files to MixingMusic.AI (up to 12 stems as WAV, MP3, FLAC, AAC or M4A). The AI proposes a mix by style and by each track’s instrument.
- Step 4
Fine-tune with per-track EQ, the MixBus with LUFS and VU, and AudioChat; then master with AI and compare the original and the master at matched loudness.
