Audio-Visual Processing Tools for Auditory Scene Synthesis

We present an integrated set of audio-visual tracking and synthesis tools to aid matching of the audio to the video position in both horizontal and periphonic sound reinforcement systems. Compensation for screen size and loudspeaker layout for high definition formats is incorporated and the spatial localisation of the source is rendered using advanced spatialisation techniques. A subjective comparison of several original and enhanced film sequences using the Vector Base Amplitude Panning (VBAP) method is presented. The results show that the encoding of non-contradictory audio-visual spatial information, for presentation on different loudspeaker layouts significantly improves the naturalness of the listening/viewing experience.
