Abstract

Techniques are provided to use near-field speakers to add depth information that may be missing, incomplete, or imperceptible in far-field sound waves from far-field speakers, and to remove the multi-channel cross talk and reflected sound waves that otherwise may be inherent in a listening space with the far-field speakers alone. In some possible embodiments, a calibration tone may be monitored at each of a listener's ears. The calibration tone may be emitted by two or more far-field speakers. One or more audio portions from two or more near-field speakers may be outputted based on results of monitoring the calibration tone.
