Which master fader? The one in Ardour or the one in
ALSA?
Sorry...Ardour's.
Ardour's steps (around 0db) are very small,
sometimes as many as 4
step for each .1db. (ctl/alt/mouse wheel or send MIDI pitch wheel in
MC mode) ALSA's step are a lot grainier. (my ice1712 with mudita24 is
.5db steps and Qasmixer gives 1db steps)
No, I'm not meaning that I can hear stairsteps as the volume changes. I
was meaning that I thought I noticed timbral changes somehow. I
experimented around with it more, and I'm pretty sure now I was just
falling for Fletcher-Munson effect -- my perception of EQ was changing
at different sound pressure levels.
6db down is one bit of 24... to go to 16 for a CD
means cutting off
bits on the bottom (maybe adding some noise) so -6 is safe.
Wow, I never would have imagined that.
So, I could mix to -6db in Ardour and still use most of the headroom on
a CD? Is there any advantage to keeping your peak level that low on the
master in the digital world? Or, put another way, if I *could* get the
whole track to behave itself and not go above -1db at loudest peak, is
there a reason not to?
