Abstract
A sound enhancement system (SES) that can enhance reproduction of sound emitted by headphones and other sound systems is disclosed. The SES improves sound reproduction by simulating a desired sound system without including unwanted artifacts typically associated with simulations of sound systems. The SES facilitates such improvements by transforming sound system outputs through a set of one or more binaural rendering filters derived from direct and indirect head-related transfer functions (HRTFs). Parameters of the binaural rendering filters are updated based on the head tracking angle of user wearing the headphones to render a stable stereo sound image. The head tracking angle may be determined from sensor data obtained from a digital gyroscope mounted in a headphone assembly.
