[PD] ICST releases Ambisonics Externals for Max/MSP

[Piotr Majdak]

Hi!

There's an ambisonic lib "iem_ambi" (in cvs externals/iem/iem_ambi) which allows 
encode to/decode from ambisonic thrid or higher order. Besides the ambimonitor 
and ambicontrol objects - let's avoid inventing the wheel again :-)
