APPARATUS AND METHOD FOR DETECTING LOUDSPEAKER CONNECTION OR POSITIONING ERRORS DURING CALIBRATION OF A MULTI CHANNEL AUDIO SYSTEM

摘要

A kind of method and apparatus, detection loudspeaker connection error and the position error multi-channel audio system during calibration are connect with multiple loudspeakers. ;In calibration process multi-channel audio system, whose angle of the loudspeaker, the voltage of measurement be identified by send test tone (451) and (460) between consistency checking angle measurement and it is a series of it is acceptable be used for each loudspeaker. When measured angle position error is not included, in acceptable angle, but it is in the hithermost loudspeaker of acceptable angle. Detect differing substantially from acceptable angle for connection error measurement. If mistake, recommendation is expression (470) to user, to make amendment appropriate. ;The method that calibrating installation (100) and audio processing equipment (120) are realized is disclosed.
