3D immersive spatial audio systems and methods

摘要

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.

主权项

1. A method for providing three-dimensional spatial audio to a user, the method comprising:
encoding audio signals input from an audio source in a virtual loudspeaker environment into a sound field format, thereby generating sound field data; dynamically rotating the sound field around the user based on collected movement data associated with movement of the user; processing the encoded audio signals with one or more dynamic audio filters; decoding the sound field data into a pair of binaural spatial channels; and providing the pair of binaural spatial channels to a headphone device of the user.
