[PD] ICST releases Ambisonics Externals for Max/MSP

[day 5]

it's not much different from PD, but the fact remains that in it's  
present state, it is incompatible with PD's API.

although i'm quite busy at the moment, i'll have a look at it

frankly though i see no advantage to porting these externals to Pd over  
using [csoundapi~]'s already implemented version of the same idea  
(Ambisonics encoding).

Initial tests seem to indicate that [csoundapi~] compiled with Intel's  
icc compiler significantly outperforms any PowerPC AltiVec instruction  
that the current Max/MSP version implements using equivalent processor  
specifications and compiler flags

you may be interested in having a look to see if you can't improve your  
code
