Re: [Sursound] Optimised Decoder matrix (Ambdec)

Clearly there's no magic here -- this scheme isn't going to let you play third-order recordings on a cube or something as irregular as The Morning Line. As Fons has pointed out on the Linux audio list, decoder design for irregular arrays is still a bit of a black art. Even if there were a

I agree with Fons here. We have used essentially this approach when we needed to play back Ambisonic material on The Morning Line (which is very irregular and needs preferably to use VBAP) right from when we first set it up back in 2008 and you definitely won't find it easy to get it work

Hi Fons, I am just following up on my previous correspondence regarding the 1st and 2nd order decoder coefficients for Ambdec, and was wondering if you would be able to provide me with the optimised matrices for Ambdec? Thanks, Paul Power -- next part -- An HTML

Hi Paul (et al.)... Over the last few months, I put together an Ambisonic Decoder Toolbox for MATLAB and GNU Octave that implements the AllRAD design technique outlined in F. Zotter and M. Frank, “All-Round Ambisonic Panning and Decoding,” J. Audio Eng Soc, vol. 60, no. 10, pp. 807–820, Nov.
