The ‘base points’ for FadeUp and FadeDown are the ‘Start’ and ‘End’ markers,
respectively; with the ‘mute level’ being (rather arbitrarily) defined to be
-46 dBFS (-30 dB from the “reference level” as shown by Rivendell’s meters. The
fades (both up and down) are logarithmic, meaning that they should be perceived
as being “uniform” to the typical human listener.
With all of that said, I’ve found that FadeUp and FadeDown are very seldom used
at most Rivendell sites. There are a couple of niche cases, but they are quite
rare. Were I redesigning the cart/cut model from scratch, I would very likely
drop those two functions entirely.
Cheers!
