Head pose mixing of audio files

A computing device comprising one or more sensors configured to provide sensor data usable to determine a pose of a user, a plurality of speakers configured to playback audio tracks, a computer processor configured to execute software instructions to determine, based at least on the sensor data, a pose of the user in a three-dimensional (3D) environment, render on a display device an object comprising a plurality of surfaces, wherein each of the plurality of surfaces are associated with a different stem tracks of an audio file and wherein each stem track is directional such that the plurality of speakers are is configured to play a stem track associated with a surface when at least a portion of the surface is visible to the user wherein a given stem track is played by the plurality of speakers with an associated spatial directionality. The processor is further configured to, in response to identifying a change in an orientation of the object relative to the pose of the user, select one or more tracks facing the user based on a pose direction of the user in relation to the identified one or more surfaces of the object, determine an audio mix of the selected one or more tracks and communicate an audio signal representative of the audio mix to the plurality of speakers to be played with an associated spatial directionality.
