Provided are methods and systems for updating a sound field in response to user movement. The methods and systems are less computationally expensive than existing approaches for updating a sound field, and are also suitable for use with arbitrary loudspeaker configurations. The methods and systems provide a dynamic binaural sound field rendering realized with the use of 'virtual loudspeakers.' Rather than loudspeaker signals being fed into the physical loudspeakers, the signals are instead filtered with left and right HRIRs (Head Related Impulse Response) corresponding to the spatial locations of these loudspeakers. The sums of the left and right ear signals are then fed into the audio output device of the user.

Virtual sound systems and methods

Provided are methods and systems for delivering three-dimensional, immersive spatial audio to a user over a headphone, where the headphone includes one or more virtual speaker conditions. The methods and systems recreate a naturally sounding sound field at the user's ears, including cues for elevation and depth perception. Among numerous other potential uses and applications, the methods and systems of the present disclosure may be implemented for virtual reality applications.
