Sound field recording using spherical harmonics (SH) has been widely used. However, too
many microphones are needed when recording sound fields over large areas, due to the …

Microphone and loudspeaker arrays are nowadays more and more employed in several
applications, such as automotive industry, entertainment, immersive teleconferencing, or …

Sound field recording aims to capture and preserve the information of the sound field in a
specific area. Typically, the recorded sound field is decomposed as a superposition of a set …

This two-part paper explores 3-D sound field reproduction by combining low order spherical
ambisonics and high order circular ambisonics in order to provide higher resolution in the …

A novel approach to non-uniform spatial resolution encoding and dimensionality reduction
of Higher Order Ambisonics spatial audio content is proposed. Space warping is applied to …

This paper describes how to encode into a spherical-harmonic representation of a 3-D
sound field using a cylindrical microphone array. The standard way to represent a sound …

Beamforming on the icosahedral loudspeaker (IKO), a compact, spherical loudspeaker
array, was recently established and investigated as an instrument to produce auditory …

This habilitation outlines the scientific works and methods undertaken to free virtual acoustic
rendering based on the spherical harmonic basis functions (Ambisonics) from excessive …

Compact spherical loudspeaker arrays are used to produce sound sculptures in
electroacoustic music by modal beamforming that orchestrates the wall reflections in the …

This paper analyzes the limitations of binaural sound that is reproduced with headphones
based on Ambisonics for Virtual Reality (VR) audio. VR audio can be provided with binaural …
