Ambisonics Objects

Ambilib is a collection of external objects for Puredata and MaxMSP. They implement some of the algorithms found in the University of York Ambisonics plugins. They were developed by Dave Malham and ported to Pd and MaxMSP by Matt Paradis. They are open source software released under the GPL.
