Sorry...Ardour's.

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.

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?
