Listening Test Methodology for Object Based Audio Rendering Interoperability using Artificial Reference Signals and Artistic Content

The preservation and representation of artistic intent are driving key words for the emerging SMPTE Immersive Audio Standard. This paper proposes a listening test methodology that will ensure that a single interoperable immersive audio OBAE bitstream, regardless of what prevailing speaker format creates the content, will allow a level of representation in commercial cinemas that achieves a baseline performance profile necessary to preserve artistic intent. Artistic intent can be preserved without disclosing rendering technologies by comparing different spatial audio renderers as a black box approach using artificial and artistic audio test content. The artificial test content shall provide maximum range evaluation of critical features and the artistic test content shall guarantee maximum acceptance from the community by using real world examples and allows for a path forward to a true single inventory immersive audio bit stream for the cinema industry and potentially other downstream deliverable.
