Hi Beat;
(For you to read only after your well-deserved time away from this forum!)
I wonder if this partially answers my previous question regarding output volume differences when using Surround Pan:
A tip from another user forum – and some research – led me to Surround Pan’s “Pan Law” options. Cubase’s manual explained that “without power compensation, the power of the sum of the left and right side will be higher (louder) if a channel is panned center than if it’s panned left or right. To remedy this, the Stereo Pan Law setting allows you to attenuate signals panned center, by -6, -4.5 or -3dB”.
So, I experimented with the different options, comparing peak levels obtained both before and after Surround Panning with different pan law options. Here's what I found: since volume output increases in direct relation to the amount toward centre one pans, one needs a corresponding "sliding scale" of pan law amounts (that is, pan law amounts that would move in very small increments, from 0dB to -.1 dB, -.2dB, -.3dB, etc) in order to exactly compensate for every possible amount of movement toward centre. So, while (for example) -3dB comes close to compensating for the volume increase when panning so that L/R = 30, it's way off when panning so that L/R = 60.
Naturally, the fixed settings of 0dB, -3dB, -4.5dB and -6dB only result in rough compensations. Is this the best one can do?
How did you manage to keep output levels the same, even after using Surround Pan to pan different amounts toward centre?
Thanks again!
