HoaLibrary (High Order Ambisonics Library) publicó recientemente una colección de objetos para operar con ambisonic tanto en MaxMSP como en Pure Data.
The HOA library allows musicians and composers to synthesize, transform and render sound fields in a creative and artistic way. It aims facilitating the understanding and the appropriation of key concepts of Ambisonics. It offers original processing like diffuse sound field synthesis, perspective distortion or spatial filtering and new graphical interfaces. The library is available for Pure Data, Max and as VST plugins.
