File requirements for mastering
Your mixdowns should be
final, and in
32 bit (24bit for analogue mixdowns)
Preparing files
Good practice: Mix without master bus processing.
If you used master bus processing, export both your version and another one without master bus processing (removed, not bypassed).
Add both versions to transfer.
Add references to other music.
Add a label copy.
A mix exchange after mastering has commenced may result into additional charges.
