Libraries
HoaLibrary		Hoa Library is a collection of C++ classes and MAX/MSP objects destined to high order ambisonic sound reproduction. It‘s totally free and made availlable by CICM, a research center bi-localized between Paris VIII University and the MSH (Maison des sciences de l‘Homme).
pg.library		The pg.library is a collection of externals for Max 5 and Max 6. It includes a data, a msp and a fft library. The Data library is a collection of externals for Max 5 and 6 that can be useful for the management, the transformation and the generation of data. The Dsp library is a collection of externals for Max 5 that allows you to pack/unpack signals and to adapt signals for the operations with packed signals. It includes a quasi-synchronous granlular synthesiser and chaotic signal generator. The FFT library is a collection of externals for Max 6 for spectral description and analysis of a signal.
