The Institute for Computer Music and Sound Technology ICST of the  
Zurich School of Music, Drama and Dance is proud to announce the  
release of a set of externals for Max/MSP for Ambisonics surround  
sound processing.

These externals are the result of research and practise using  
Ambisonics since 2000 and have been tested and used in numerous  
concerts, compositions and installations.

The ICST releases these externals under the terms of the GNU Lesser  
General Public License (LGPL).
For more information regarding this license go to http://www.gnu.org.

This release comprises four objects for surround sound processing and  
source-control in three dimensions:

ambiencode~  –  encode n audio-channels in up to 3rd order ambisonic  
b-format

ambidecode~  –  decode up to 3rd order ambisonic b-format to n audio-
channels

ambimonitor  –  graphical user interface object for sound-source  
placement (Mac only)

ambicontrol  –  control sound-sources in the ambimonitor in a variety  
of ways (Mac only)

This release has been developed and tested on Mac OS 10.4 (Tiger) and  
Max/MSP 4.5.x

The DSP-objects have also been compiled and tested under Windows XP  
SP2 and Max/MSP 4.5.x. Due to the considerable task of porting the  
GUI object to Windows, this release for Windows contains only the  
audio-objects.

The files can be downloaded from:

We hope you’ll enjoy them!
