Human hearing is known to be sensitive to the distances of sound sources. However, spatial-sound rendering systems typically do not allow controlling the distance of the auditory objects. This paper proposes a distance-rendering method that uses standard 5.1 loudspeaker layouts. The proposed method applies an input signal to multiple loudspeakers and controls the gains and the coherence of the loudspeaker signals. In addition, the method is combined with amplitude panning, thus allowing to continuously control both the distance and the direction of the auditory objects. Based on listening tests, the proposed method was found to provide the ability to realistically manipulate the perception of both direction and distance.
