Abstract:
A method and an apparatus for detecting loudspeaker connection errors and positioning errors during calibration of a multichannel audio system to which a plurality of loudspeakers is connected. Within a calibration process of a multichannel audio system, the loudspeaker whose angle is to be measured is identified by emitting a test tone ( 451 ) and verifying ( 460 ) the conformance between angles measured and a range of acceptable angles for each loudspeaker. A positioning error is detected when the measured angle is not included in the range of acceptable angles but in the range of acceptable angles of the closest speaker. A connection error is detected when the measured angle is very different from the range of acceptable angles. In case of errors, a recommendation is expressed ( 470 ) to the user in order to make the appropriate corrections. A calibration device ( 100 ) and an audio processing device ( 120 ) implementing the method are disclosed.

Claim (Index 1):
A method for detecting loudspeaker connection errors and positioning errors in a multichannel audio system comprising an audio processing device, a set of loudspeakers, and a calibration device, comprising at a processor of the calibration device:\n for at least one loudspeaker, measuring at least one of an azimuth angle and an elevation angle of the loudspeaker in a three-dimensional coordinate system when a test tone is played on the loudspeaker, the measuring comprising:\n displaying on a screen of the calibration device at least an image captured by a camera of the calibration device and an overlaid picture indicating where to aim; and \n obtaining validation when the calibration device is aimed at the loudspeaker, aligning on the screen of the calibration device the overlaid picture with the captured image of the loudspeaker; \n verifying that the measured angles are comprised in a range of acceptable values for the loudspeaker, and in case at least one measured angle is outside the range of acceptable values for the loudspeaker, notifying a user of an error.
