While most modern surround sound formats specify ideal loudspeaker placement, it is often impractical to comply with these specifications in most homes. In this paper we propose a simplified approach to spatial calibration for incorrectly set up surround sound systems. The proposed system utilizes a microphone array embedded into a component of the reproduction system whose location is predictable, such as a sound bar or a front center speaker. In addition to estimating loudspeaker positions, the proposed system is able to estimate a listener’s position using voice input and calibrate the surround sound system utilizing the estimated listener position. Tests conducted in a typical living room setup show that the proposed system is able to improve the listening experience on such compromised systems with only simple user interactions such as voice commands.
