Multi-channel signals captured by spatially separated sensors often contain a high level of
data redundancy. A compact signal representation enables more efficient storage and …

Delivering high-quality spatial audio in the Ambisonics format requires extensive data
bandwidth, which may render it inaccessible for many low-bandwidth applications. Existing …

To auralise a room's acoustics in six degrees-of-freedom (6DoF) virtual reality (VR), a dense
set of spatial room impulse response (SRIR) measurements is required, so interpolating …

Spatial room impulse responses (SRIRs) capture room acoustics with directional
information. SRIRs measured in coupled rooms and spaces with non-uniform absorption …

In order to transmit sound-scenes encoded into the higher-order Ambisonics (HOA) format to
low-bandwidth devices, transmission codecs are needed to reduce data requirements …

This paper presents an underwater soundfield visualisation method for passive-sonar
applications employing circular hydrophone arrays. The method operates by segregating …

Spherical microphone arrays may be used to capture the directional characteristics of a
room acoustic response. Spatial impulse response rendering (SIRR) is a method for …

Scene-based spatial audio formats, such as Ambisonics, are playback system agnostic and
may therefore be favoured for delivering immersive audio experiences to a wide range of …

In this article we present beamix, an audio engine and its graphical user interface which
allow one to produce directional audio effects (FX), that is, sound transformations localized …

This thesis consists of five publications that focus on the development and evaluation of
techniques designed for passive sonar applications utilising hydrophone arrays. The …
