Abstract
The systems and methods described herein can be configured to identify, manipulate, and render different audio source components from encoded 3D audio mixes, such as can include content mixed for azimuth, elevation, and/or depth relative to a listener. The systems and methods can be configured to decouple depth encoding and decoding to permit spatial performance to be tailored to a particular playback environment or platform. In an example, the systems and methods improve rendering in applications that involve listener tracking, including tracking over six degrees of freedom (e.g., yaw, pitch, roll orientation, and x, y, z position).
