I’m mixing a 7.1 (side surround ie what Nuendo calls “Music”) project and something is off with the front-to-rear pan law. I currently don’t have my surround speakers set up as I’m doing the stereo mix first, so I’m monitoring off a stereo downmix bus with the Mixconvert 6.0 plugin that is inserted in the panner by default. (The bus is 7.1 input to 2.0 output).
My left/right pan law obeys the project setting (equal power) so moving objects left to right results in consistent volume across the stereo sound stage as expected. However, when i place a sound midway between say front/side or side/rear I am getting a 3dB level bump compared to if it’s only in the fronts, or sides, or rears. Positioning a sound at a single speaker or midway left-right between a pair of speakers gives me the correct level. So left-right pan law is ok, but front-rear seems to be using a 0dB pan law so the sound gets louder when panned to a position between the speakers.
Moving a sound from surrounds to fronts over time thus causes inconsistent volume changes which is unacceptable, and not what I’m used to in Pro Tools. Doesn’t matter what downmix levels I set for surrounds in mixconvert (0dB, -3dB, -6dB) I still get the level increase when in a midway position.
(After setting up my surround speakers I will test whether this is occurring in the 7.1 soundfield or in the MixConvert Plugin)
