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 8):
A calibration device for performing angular measurement of loudspeaker angular positions, verifications of these positions according to a range of acceptable positions and interactions with a user in a multichannel audio system, comprising:\n a network interface configured to request a loudspeaker to play back a test tone; a camera configured to capture images representing a scene in front of the device; at least one sensor configured to determine azimuth, elevation and roll angles of the device; a screen configured to display at least an image captured by the camera, an overlaid picture indicating where the user should aim and a message instructing the user what element to target; a user input interface configured to obtain validation from the user when the calibration device is aimed at the loudspeaker, aligning on the screen of the calibration device the overlaid picture with a captured image of the loudspeaker; a processor configured to, for each loudspeaker:\n after obtaining validation, measure at least one of the azimuth and elevation angles of the loudspeaker in a three-dimensional coordinate system when the test tone is played on the loudspeaker; \n verify that the measured angles are comprised in a range of acceptable values for the loudspeaker, and \n in case at least one measured angle is outside the range of acceptable values for the loudspeaker, notify the user of the error.
