AB  - This paper details the design and evaluation of a novel frequency-domain digital signal processing algorithm intended for upmixing of previously recorded audio to larger 3D loudspeaker arrays either by itself or in combinationwith other upmixing techniques. The algorithm attempts to mimic the dynamic and complex phase variances experienced by listeners in concerts of acoustic music. Critical listening evaluations support the algorithm’s effectiveness in increasing the perceived spaciousness and liveliness and show a significant preference for its use.
