- MPEG-H 3D audio format, a standard audio format that supports multi-channel encoding/decoding on up to 64 loudspeaker channels and 128 codec core channels.
- 360 Reality Audio format started, by giving them the technical tools to map their audio tracks in space, working on vocals and instruments as “objects” evolving in a 360 environment surrounding the listener.
