Spatial audio reproduction based on head-to-torso orientation

A media system, comprising:

• one or more processors configured to:
• detect a head movement of a head of a user based on head orientation data generated by a device,
• determine a torso movement of a torso of the user based at least in part on an image sensor that is arranged to track a pattern of clothing on the torso of the user, wherein the torso movement differs from the head movement,
• determine a head-to-torso orientation based at least in part on the head movement and the torso movement,
• select a head-related transfer function (HRTF) according to the head-to-torso orientation, and
• apply a binaural audio filter to an audio input signal to generate an audio output signal, wherein the binaural audio filter is based on the HRTF;
• and
• one or more speakers configured to play the audio output signal to recreate spatial audio of sounds that accounts for spatial audio effects of the head-to-torso orientation.

A non-transitory computer readable medium containing instructions, which when executed by one or more processors of a media system, cause the media system to perform a method comprising:

• detecting a head movement of a head of a user based on head orientation data generated by a device;
• determining a torso movement of a of the user based at least in part on an image sensor that is arranged to track a pattern of clothing on the torso of the user, wherein the torso movement differs from the head movement;
• determining a head-to-torso orientation based at least in part on the head movement and the torso movement;
• selecting a head-related transfer function (HRTF) according to the head-to-torso orientation;
• and
• applying a binaural audio filter to an audio input signal to generate an audio output signal, wherein the binaural audio filter is based on the HRTF.
