1. A headphone system, comprising:
- a headphone for providing sound from virtual speakers to a listener via a plurality of sound paths that are filtered with a plurality of filters;
a sensor for sensing an angular velocity of a movement of the listener; and
a processor for receiving the angular velocity,wherein, in response to the received angular velocity, the processor is configured to;
calculate delays in the plurality of sound paths and filter coefficients for the plurality of filters based on the angular velocity, andinsert the calculated delays in the plurality of sound paths and adjust the plurality of filters with the calculated filter coefficients.

Abstract
A headphone system includes a headphone, a sensor, and a processor. The headphone may provide sound from virtual speakers to a listener via a plurality of sound paths that are filtered with a plurality of filters. The sensor may sense an angular velocity of a movement of the listener. The processor may receive the angular velocity and may calculate delays in the plurality of sound paths and filter coefficients for the plurality of filters based on the angular velocity, and insert the calculated delays in the plurality of sound paths and adjust the plurality of filters with the calculated filter coefficients.
