Be advised that there is many ways of mapping faders to mulipliers.
Depending on your practice it is common to have the 0dB (unity gain)
mark somewhere 4/5 up the fader's range, which is inherited from
analogue mixing desks and which I have found useful in the digital
domain as well (despite the danger of clipping at the dac). The mapping
of a fader's value to the actual multiplicative value is also a matter
of feel (tactile). I don't know if there is much research about this
topic, I personally prefer the [fadtodb] abstraction by Thomas Musil
(iemabs/iemlib) which we use for our productions here at the IEM, and
which to my humble opinion comes closest to the analogue desks i love.
