Presentation

Sound space is one of the principal dimensions of the contemporary musical thought, specialy in the electroacoustic music domain but also in intermedia arts. In this context, the CICM has made spatialization its principal research axis. This project’s aim is to give to musician saptialization models based on high order ambisonics and sound fields synthesis. This project is developed in a part of the Paris-8 University LABEX H2H. It takes place between june 2012 and july 2013 in the MSH Paris-Nord and the plate-forme Arts-Sciences-Technologies. Partners are Louis-Lumière school and IRCAM.

Hoa Library proposes a set of objects for MaxMSP software destinated to high order ambisonic sound reproduction. It permits to musicians, compositors to synthesize, control and transform sound fields. Thanks to its modular architecture, it make easier to use the circular harmonics and the audiodigital processing creation in the ambisonic domain. So, it proposes an original approach of the soundfield and gives new creations possibilities.

This library, developed in C++, is entirely free and permits you to take advantage of it in multiple platforms. Directed to ambisonics techniques, it offers nevertheless a bridge  towards binaural techniques and allows to envisage an extension towards surround restoration systems or still transaurals. This project reflects a large conception of spatialization and leads to design new tools for trajectory creation and sound field.
