Carrouso project combines technologies for recording, transmission and rendering of 3D sound scenes. The rendered virtual scene includes both the sound content, and the spatial and room acoustic description of the performance space. MPEG-4 tools are utilized for encoding of this data, using the general audio coding for compression of sound streams, and the scene description tools for creating virtual 3D audio scenes. We describe the creation of the virtual acoustic space, carried out with the help of a room acoustics analysis software and an authoring tool. A visual representation of the virtual sound scene is also transmitted to the renderer, and it acts as a user interface allowing renderer-side scene modification via the interaction mechanisms provided in MPEG-4.
