Abstract: We developed a method that extracted the interchannel coherent component from multichannel audio signal. In this paper two subjective evaluation experiments for testing the upmix performance of our method are shown. In the first experiment, stereo signals were upmixed to 4-channel signals in which channels were set at +-30° and +-60°. The subjective evaluation with MUSHRA method showed that our method was superior to the conventional methods. In the second experiment, signals of 4 channels located at +-30° and +-110° were upmixed to 8-channel signals in which four of the channels were set at the upper layer. The subjective evaluation showed that there were no significant differences between the upmixed 8-channel sound and the original 4-channel sound in terms of spatial impression.
