An Open 3D Audio Production Chain Proposed by the Edison 3D Project

In this paper we present a production chain for Next Generation Audio formats that combines standard digital audio workstations with external 3D audio rendering software using an open communication protocol. We first describe the scope of the Edison 3D project. In a second part, we revisit existing 3D audio formats outlining the need for an open format for content creation and archiving. We then describe the tools developed in Edison 3D enabling user interaction, storage of object positions in the timeline, monitoring of audio content in various rendering formats (stereo, 5.1, binaural, WFS, HOA), and export into the open and recently standardized (ITU BS.2076) 3D audio format: Audio Definition Model. We finally provide an outlook into future work.
