Abstract
A sound reproduction system for reproducing an audio signal as originating from a first direction relative to a nominal position () and orientation of a listener is provided. The system comprises a first sound transducer arrangement () arranged to generate sound reaching the nominal position () from a first position corresponding to the first direction; and a second sound transducer arrangement () arranged to generate sound reaching the nominal position () from a second position corresponding to a different direction than the first direction. The arrangements may specifically be loudspeakers positioned at the given positions. A drive circuit () generates a first drive signal for the first sound transducer arrangement () and a second drive signal for the second sound transducer arrangement () from the audio signal. The first position and the second position are located on a sound cone of confusion for the nominal position () and the nominal direction. A more flexible loudspeaker positioning may be achieved.
