Claim Text:
1. A computer-implemented method, comprising: receiving an image captured by a mobile computing device, the image including at least a portion of a user of the mobile computing device; analyzing the image to determine a head position of the user with respect to the mobile computing device; determining a rotation of the head of the user on a vertical axis based upon the head position of the user with respect to the mobile computing device; receiving a stereo audio input including a left input audio signal corresponding to a left audio channel and a right input audio signal corresponding to a right audio channel; generating a left output audio signal based at least in part upon the left input audio signal and a left cancellation signal, wherein the left cancellation signal is generated by applying a first phase inversion, a first delay and a first filter to a right audio signal corresponding to the right input audio signal, and the first phase inversion determined based at least in part upon the head position of the user and the rotation of the head of the user on the vertical axis; and providing the left output audio signal and the right audio signal for stereo presentation.
