New immersive and object-based multichannel audio formats for cinema, entertainment and cinematic VR

In recent years, several audio technology companies and standardization organizations (including Dolby, Auro, DTS, MPEG) have developed new formats and tools for the creation, archiving and distribution of immersive audio content in the cinema or broadcast industries. These developments extend legacy multi-channel audio formats to support three-dimensional (with height) sound field encoding, along with optional audio object channels accompanied with positional rendering metadata. They enable efficient content delivery to consumer devices and flexible reproduction in multiple consumer playback environments, including headphones and frontal audio projection systems. In this talk, we'll review and illustrate the state of these developments and discuss perspectives and pending issues, including virtual reality applications.
