Abstract

Panning laws for multi-loudspeaker setups, for example vector base amplitude panning, are typically derived based on either low or high frequency assumptions. It is well known, however, that auditory cues for both localization and loudness differ at these frequencies. This paper investigates the use of dual-band panning, whereby low and high frequency gains and normalization are applied separately. Single- and dual-band rendering algorithms are described, with predicted theoretical localization, spectral balance, and source extent cues given. A multiple stimulus test is described, performed for a number of trajectories rendered to a periphonic nine-loudspeaker ITU-R BS.2051-1 setup, with rated attributes based on predicted sources of error. Results are reported, detailing differences between both theoretical predictions and systems under test.
