Spheroidal ambisonics: Spatial audio in spheroidal bases [PDF]
JASA Express Letters, 2021 Ambisonics is an established framework to capture and reproduce spatial sound fields based on the spherical harmonics representation [Gerzon (1973). J. Audio Eng. Soc. 21(1), 2–10].

Improving Csound's Ambisonics decoders [PDF]
, 2019 This paper describes the efforts we devoted to improve Ambisonics decoders in Csound. Current version of the existing opcode, namely bformdec1, has some limitations that should be surpassed in order that the decoders better fulfill the Ambisonics criteria.

Directional Emphasis in Ambisonics [PDF]
IEEE Signal Processing Letters, 2018 We describe an ambisonics enhancement method that increases the signal strength in specified directions at low computational cost. The method can be used in a static setup to emphasize the signal arriving from a particular direction or set of directions.

Ambisonics Sound Source Localization With Varying Amount of Visual Information in Virtual Reality
Frontiers in Virtual Reality, 2021 To reproduce realistic audio-visual scenarios in the laboratory, Ambisonics is often used to reproduce a sound field over loudspeakers and virtual reality (VR) glasses are used to present visual information.

Assessing the ecological validity of soundscape reproduction in different laboratory settings [PDF]
PLoS ONE, 2022 The ever-growing body of soundscape research includes studies conducted both in everyday life environments and in laboratory settings. Yet, laboratory settings differ from in-situ and therefore may elicit different perceptions. The present study explores

Nearfield binaural synthesis and ambisonics [PDF]
Journal of the Acoustical Society of America, 2007 Ambisonic encodings can be rendered binaurally, as well as for speaker arrays. This process is developed for general high-order Ambisonic encodings of soundfields containing near as well as far sources. For sufficently near sources an error is identified, resulting from the limited field of validity of the freefield harmonic expansion.

Multiple scattering ambisonics: Three-dimensional sound field estimation using interacting spheres [PDF]
JASA Express Letters, 2021 Rigid spherical microphone arrays (RSMAs) have been widely used in ambisonics [Gerzon (1973). J. Audio Eng. Soc. 21, 2–10] sound field recording. While it is desired to combine the information captured by a grid of densely arranged RSMAs for expanding ...
