FIELD: physics, acoustics.
SUBSTANCE: invention relates to means of estimating positions of loudspeakers in surround sound systems. The system comprises motion sensors (201, 203, 205), configured to determine motion data for a user portable unit, where motion data describe movement of the user portable unit. A user input device (207, 209) receives user activations indicating that at least one of the current position and orientation of the user portable unit is associated with a loudspeaker position when user activation is received. User activation may arise, for example, when a user presses a button. An analysing processor (211) then generates loudspeaker position estimates in response to motion data and user activations. The system can enable, for example, estimation of positions of speakers based a handheld device, for example a remote control panel, directed towards a speaker or mounted thereon.
EFFECT: high accuracy of estimating loudspeaker positions in surround sound systems.
