Incoherent idempotent ambisonics rendering
2017 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA), 2017We describe a family of ambisonics rendering methods that is based on optimizing the soundfield component that lies in the null space of the operator that maps the loudspeaker signals onto the given ambisonics representation. In contrast to traditional rendering approaches, the new method avoids the coherent addition of loudspeaker contributions to the

Machine consciousness, ambisonics
Kybernetes, 2009PurposeThe purpose of this paper is to review machine consciousness (MC) and machine modelling of consciousness (MMC) with acknowledgement that their study may contribute to understanding of biological consciousness. The death of Peter Fellgett, the first Professor of Cybernetics in the UK, is noted, with a brief reference to his work on infra‐red ...

Applied Acoustics, 2018
Abstract In ambisonics, the number of loudspeakers must be greater than or equal to the requirement of the ambisonic order. On the one hand, if the number of loudspeakers in an ambisonic system satisfies the minimum requirement exactly, localization in the lateral regions can be poor. On the other hand, the use of a large number of loudspeakers in an

Development of an Ambisonic Guitar System
2021The term sound spatialisation indicates a group of techniques for organising and manipulating the spatial projection and movement of sound in a physical or virtual listening environment. An Ambisonic Guitar System has been devised and realised, with the project name GASP: 'Guitars with Ambisonic Spatial Performance'.

A Denoising Methodology for Higher Order Ambisonics Recordings
2018 16th International Workshop on Acoustic Signal Enhancement (IWAENC), 2018We propose a denoising methodology for spatial audio recordings acquired with spherical microphone arrays and encoded with Higher Order Ambisonics (HOA). The goal is to suppress the noise field impinging on the microphone array, while preserving the full spatiality of the desired soundfield, produced by an acoustic source of interest within the ...

Ambisonic reproduction of sound
Electronics and Power, 1973Earlier this year, the correspondence columns of Electronics & Power were filled with letters arguing the pros and cons of quadraphonics. One correspondent put forward the view that ambisonic reproduction had decided advantages over quadraphonic reproduction. In this article, Prof. Fellgett expands his views.

In the rapidly evolving fields of virtual and augmented reality, accurate spatial audio capture and reproduction are essential. For these applications, Ambisonics has emerged as a standard format. However, existing methods for encoding Ambisonics signals
