Original Abstract Submitted
the various aspects of the disclosure here enable a content creation side to control how discrete audio objects that make up a sound program are rendered by a decoding side to achieve greater realism, while enabling the decoder side to also control the rendering process to consider the positions and orientations of the objects as virtual sound sources relative to the listener. the same sound program can thus be optimally rendered by a variety of decoder side formats, such as binaural on headphone, cross-talked cancelled binaural on a stereo pair of speakers embedded in a device, or multichannel on an immersive loudspeaker layout, e.g., planar such as 5.1 and 7.1 surround sound layouts, 3d such as 7.1.4 or 22.2, etc. other aspects are also described and claimed.
