[Chris Borjis] “if you can make sure your audio peaks bounce between -10 and -6 on your
editing systems audio meters, it should be close enough.”
Unfortunately beta SP doesn’t have that much headroom. Peaks shouldn’t be more than 8db above your reference tone.
Ironically, reference tone only really exists for analog dubs. In the digital domain, it is irrelevant.
If your tone is set to -20db on your QT file, then your audio peaks should not exceed -12db if it is going to go to SP beta. You either have the choice of adjusting your master level to make this so or choosing a reference tone level that is 8db below your peaks. The better practice is the former as the dub house will be expecting those levels. As others have said, don’t present higher levels (ie close to 0dbfs) as they will be often too high for analog routers etc at the dub house.
