Virtual Source Panning Using Multiple-Wise Vector Base in the Multispeaker Stereo Format

In the last few decades, various panning algorithms have been proposed to generate virtual sound localization in loudspeaker systems. Vector Base Amplitude Panning (VBAP) is the most widely adopted pair wise amplitude panning method. However, pair-wise amplitude panning has a directional discontinuity problem in the multichannel surround panning. In particular, sound localization for the virtual source does not smoothly vary in the direction of the near speaker. While coincident panning using multiple loudspeakers, such as Ambisonics, performs better, it has less stability in sound localization due to the precedence effect. In this paper, a multiple-wise vector base virtual source panning algorithm is proposed.
