Abstract : Recent technological improvements in audio reproduction systems increased the possibilities to spatialize sources in a listening environment. The spatialization of reproduced audio is highly dependent on the recording technique, the rendering method, and the loudspeaker configuration. While object-based audio production reduces this dependency on loudspeaker configurations, related authoring tools are still difficult to interact with. In this paper, we investigate the issues of spatialization techniques for object-based audio production and introduce the Spatial Audio Design Spaces framework (SpADS), which describes the spatial manipulation of object-based audio. Based on interviews with professional sound engineers, our morphological analysis clarifies the relationships between recording and rendering techniques that define audio objects for 3D speaker configurations, allowing the analysis and the design of advanced object-based controllers as well.
