Descrição: In analog, there were many "plant standards," which made it rough to move audio from plant to plant. In digital, it's simple: Full scale is OdBFS - not +10dB, not even +4dB; all Is are defined at OdBFS. The trick here is to always keep the audio in digital - right from the mixing board. The minute it hits analog again, the signal needs to go through analog-to-digital converters, which is where the nightmare begins; both levels and phasing are bound to get messed up.
