A system for determining loudspeaker position estimates comprises motion sensors (201,203) and a movement processor (205) arranged to determine motion data for a user movable unit where the motion data characterizes movement of the user moveable unit. A user input interface (207) receives user inputs and a user processor (209) processes them into user activations which indicate that at least one of a current position and orientation of the user movable unit is associated with a loudspeaker position. An analyzing processor (211) then generates loudspeaker position estimates in response to the motion data and the user activations. The system thus performs speaker position estimations based on (i) the motion data of the user moveable unit being pointed towards or positioned on a speaker and (ii) the user activations.
