Abstract

A subjective evaluation of Virtual Home Theatre systems (VHT) for loudspeaker and headphone reproduction is presented in this paper. Several algorithms for loudspeakers and headphones were selected and applied to six different multichannel audio programs. A subjective experiment was performed for each configuration using screened listeners to assess the performance of these VHT algorithms in terms of overall sound reproduction quality. A paired comparison method was chosen, with the discrete 5-channel reproduction (3/2) system as a reference in the loudspeaker test, and the stereo downmix of the 5-channel material in the headphone test. The stereo downmix was also compared to the 5-channel reference in the case of the loudspeaker reproduction. The experimental design and the detailed analysis of results are presented in this paper.
