Dual frequency band amplitude panning for multichannel audio systems
Presentation / Conference
Hughes, R., Franck, A., Cox, T., Shirley, B., & Fazi, F. Dual frequency band amplitude panning for multichannel audio systems. Presented at 2018 AES International Conference on Spatial Reproduction - Aesthetics and Science, Tokyo, Japan

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... Read More about Dual frequency band amplitude panning for multichannel audio systems.
