Abstract

The introduction of new techniques for audio reproduction such as binaural technology, Wave Field Synthesis and Higher Order Ambisonics is accompanied by a paradigm shift from channel-based to object-based transmission and storage of spatial audio. The separate coding of source signal and source location is not only more efficient considering the number of channels used for reproduction by large loudspeaker arrays, it will also open up new options for a user-controlled soundfield design. The paper describes the technological change from stereophonic to array-based audio reproduction techniques and introduces a new proposal for the coding of spatial properties related to auditory objects.
