Coordinate conversions in audio metadata for next-generation audio

Positions of audio objects are described using polar or Cartesian coordinates in audio metadata for next-generation audio. The existing coordinate conversion specified in Rec. ITU-R BS.2127 depends on the specific loudspeaker layout. We propose a coordinate conversion method applicable to any loudspeaker layout and conduct a subjective test to verify it.

Abstract

Positions of audio objects are described using polar or Cartesian coordinates in audio metadata for next-generation audio. The existing coordinate conversion specified in Rec. ITU-R BS.2127 depends on the specific loudspeaker layout. We propose a coordinate conversion method applicable to any loudspeaker layout and conduct a subjective test to verify it.
