Spatial audio has been studied for several decades, but has seen much renewed interest
recently due to advances in both software and hardware for capture and playback, and the …

This article details an investigation into the perceptual effects of different rendering
strategies when synthesizing loudspeaker array room impulse responses (RIRs) using …

Reproduction of spatial properties of recorded sound scenes is increasingly recognised as a
crucial element of all emerging immersive applications, with domestic or cinema-oriented …

This papers presents a parametric method for perceptual sound field recording and
reproduction from a small-sized microphone array to arbitrary loudspeaker layouts. The …

Multizone soundfield reproduction over an extended spatial region is a challenging problem
in acoustic signal processing. We introduce a method of reproducing a multizone soundfield …

This paper investigates sound-field modeling in a realistic reverberant setting. Starting from
a few point-like microphone measurements, the goal is to estimate the direct source field …

A wave field estimation method exploiting prior information on source direction is proposed.
First, we formulate a wave field estimation problem as regularized least squares, where the …

In general, techniques are described for transitioning an ambient higher order ambisonic
coefficient. A device comprising a memory and a processor may be configured to perform …

The capture and reproduction of spatial audio is becoming increasingly popular, with the
mushrooming of applications in teleconferencing, entertainment and virtual reality. Two …

ABSTRACT A device comprising a memory and one or more processors may be configured
extract, from the bitstream, a type of quantization mode. The one or more processors may …
