The rationale behind this is that at LF the L and R signals will add more or less in phase, while at HF the phases are random and what gets added is the power. The mixer app I've been developing has only Ambisonic panning. If you want stereo, you use a first order horizontal only bus (3 channels), use the -45 to +45 degrees range of the panner, and decode to stereo in the master strip. Then it's that decoder that determines the relative center gain of the panner, and it's no problem to make it frequency dependent so you get -6 dB at LF and -3 dB at HF. > I will look at having separate pan controls for each channel on one strip, > as I'm reminded from talking to Paul that Ardour has this :) A2 had this, but no way to change the relative gains of L and R. The full matrix from L,R to L',R' has four coefficients. One of those factors out as channel gain, so three remain. So a really universal stereo -> stereo 'panner' must have three independent controls. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
