2.5D Sound Field Reproduction Using Higher Order Loudspeakers
Cybernetics and Information Technologies, 2015 Using 3-Dimensional (3D) sound sources as secondary sources to 2-Dimensional (2D) sound field reproduction, it is termed 2.5-Dimensional (2.5D) sound field reproduction which is currently drawing broad interest in acoustic signal processing.

2.5D sound field reproduction in higher order Ambisonics [PDF]
2014 14th International Workshop on Acoustic Signal Enhancement (IWAENC), 2014 In this paper, we present a theoretical basis and implementation strategies for 2.5-dimensional (2.5D) sound field reproduction in higher order Ambisonics. The issue associated with 2.5D system is the intrinsic dimensionality mismatch between a desired 2-dimensional (2D) sound field and the loudspeaker employed for reproduction, whose spatial ...

Spherical harmonic representation of the observed directional wave front in the time domain [PDF]
JASA Express Letters, 2022 Sound field reproduction algorithms require loudspeaker directivity, which is usually measured at discrete frequencies. A time domain model of loudspeaker directivity benefits broadband applications. This Letter proposes the concept of a directional wave
