  • System, method, and apparatus for generating and digitally processing a head related audio transfer function
    Patent number: 10959035
    Abstract: The present invention provides for an apparatus, system, and method for generating a head related audio transfer function in real time. Specifically, the present invention utilizes unique structural components including a tragus structure and an antihelix structure in connection with a microphone in order to communicate the location of a sound in three dimensional space to a user. The invention also utilizes an audio processor to digitally process the head related audio transfer function. The system may also be utilized to pan the directionality of audio sources within a virtual environment at least partially in response to movement of a user.
