[PD] [PD-announce] HoaLibrary for PD - High Order Ambisonics Library

[Pierre Guillot]

Hi Thomas,

We thought that 10.6 for the deployment target was enough but it seems that
we were wrong. We use some dependencies to optimize the matrix
multiplications (the high order ambisonics involve a lot of computations)
and we thought that the efficiency of the optimizations depends of the
deployment target (in fact, we don't really know, we have to try). So we'll
try with 10.5 and I hope that you'll be able to use Hoa with the next
release.

All the best,
Pierre
