Thanks for that feedback - I have HARPEX, but did not realise it does
third-order horizontal? One drawback with Harpex is it does not do height

you could do HARPEX on the 8 horizontal speakers, then take two virtual

there are no hard upper limits. the absolute lower limit is (N+1)².
in horizontal layouts, i find 8 too much for first order, and 12 too
much for third order. the issue is that additional

Thank for all this guidance.
If the min is (N+1)².
Surely for 3rd order that is
(3+1)² = 16 speakers?
This is what has been confusing me as I see reports of third order over 8

I did wonder about using Daniel Courville's plugins to do decoding for the
height info separate to HARPEX. The HARPEX decoding does sound good ( how can I
confirm it is 3rd order over 8 speakers?) and so if I could add height using
another approach that would be good. I need to look at how to ge

The minimum is (M + 1)^2 for 3D, and (2 * M) + 1 for 2D, but
- You better use at least on more,
- For 3D, the minimum is 8, even for first order. That is because

I successfully used b-format impulse responses from York Uni's OpenAir
library in my 12 speaker cube array at the end of June. This was for an
assessment for my MA in Creative Music Practice at University of Wales
Newport. The IR from York Minster was spectacular and gave a solidly 3D

Dave,
It's possible to skip the A/D conversion by using amplifiers with
digital inputs. Texas Instruments have a 8 channels digital to PWM
converter that can drive D-class amps with PWM inputs; that means only
one A/D conversion, done by the speaker...

Meridian currently include Ambisonic

(Although whether these are analogue comes
down to definitions.)
