This report is very much in line with my observations too, in the concert hall and in optimal studio conditions. I would say that HOA start to be usable for focused point source around the 5th order, and gets better higher up with the problems of then having the speaker setup to fill it… so when it was time for me to write a high channel count piece for the BEAST, I opted for a hybrid setup of: - Third order ambisonic for envelopment and fluffy positioning - point sources (5:2 + an elevated) for cheats strong positioning for everyone* - a quad of real distant speakers in the far corners**
Total: 28 channels, that can be rendered in a 8:4 hemispherical array at worse, and in optimal conditions, is capitalising on the best of all worlds. Quite portable. Obviously, calibration between the different setups was needed, is easily done, with the proper pink noise bursts. It has been played quite successfully in many different settings. I hope this helps p * because sweet spot still exist in all of them except WFS and even that is not super solid) ** because all of the other are based on being on the sphere, again WFS is good for stuff outside the ring but not convenient for many other things like spectral flatness... > On 20 Apr 2019, at 09:08, Augustine Leudar <augustineleu...@gmail.com> wrote: > > Ps if I remember rightly Peter Stitt may have done some studies comparing > vbap and ambisonics in an octoganal array at sarc you could check him out. > > On Saturday, 20 April 2019, Augustine Leudar <augustineleu...@gmail.com> > wrote: > >> I havent done a study on it but ive done hundreds of compositions and >> installations and the differences are pretty obvious.
