Yes

Fons and Jörn,
If i can stretch your time a little further:

Yes, but it doesn't make sense doing so. With six speakers you can't

Thanks for the suggestion - actually I was only using 2nd order encoding

It never hurts :-)

Thanks a lot Fons. Re. near-field compensation, I'm guessing it wouldn't
hurt to keep this enabled in ambdec when combining with vector-panning.
Is this correct?

This is quite simple, linear gain and delays are both is proportional

Dear list,
I'd like some advice on implementing gain and delay compensation for an
irregular speaker array with a listener in a fixed position. This
probably is a question for Fons Adriaensen if he is here, as it concerns
a hybrid ambisonic/vector-panning system using ambdec:
