Hi,
I'm using a MatrixMixer, and I'm a little confused about the metering
options available to me. Ideally, I want a metering value as a floating
point value between 0 and 1, for use in a metering graph (similar to the one
in the MatrixMixerTest project).
What I'd like to know is: Should I use kMatrixMixerParam_PostAveragePower,
and then convert this decibel value to a float? If so, does anyone have the
right equation for this conversion?
Or, should I use kMatrixMixerParam_PostAveragePowerLinear, and if so, what
max range does this cover?
I might just be a bit of a decibels novice, but I'm not quite sure which is
right for my needs :-(
Thanks in advance,
Dave.
