Conference Paper

Producing 3D Audio in Ambisonics

Authors: Frank, Matthias; Zotter, Franz; Sontacchi, Alois

AES Conference: 57th International Conference: The Future of Audio Entertainment Technology – Cinema, Television and the Internet · Paper 6-3 · March 2015

Abstract

Ambisonics is a 3D recording and playback method that is based on the representation of the sound field excitation as a decomposition into spherical harmonics. This representation facilitates spatial sound production that is independent of the playback system. The adaptation to a given playback system (loudspeakers or motion-tracked headphones) is achieved by a suitable decoder. This contribution gives an overview of the current state-of-the-art in Ambisonics including content production using Ambisonic main microphone arrays or panning of virtual sources, spatial effects, and reproduction by loudspeakers and headphones. The software for the whole production chain is already available as a VST-plugin suite for digital audio workstations.
