Original Abstract Submitted
a media system and a method of using the media system to reproduce spatial audio based on head-to-torso orientation, are described. the method includes determining a head-to-source orientation and a head-to-torso orientation based on head orientation data generated by a head tracking device. determining the head-to-torso orientation includes determining torso movements based on movements of the head. the torso can be determined to move when the head movements meet a head movement condition, such as a predetermined angle of movement or pattern of movement. a binaural audio filter that is based on a head-related transfer function corresponding to both the head-to-source orientation and the head-to-torso orientation is applied to an audio input signal to generate an audio output signal. the audio output signal is played to accurately recreate spatial audio having sounds emitted to the user by a sound source. other aspects are also described and claimed.
