Beyond Surround Sound - Creation, Coding and Reproduction of 3-D Audio Soundtracks

Authors: Jot, Jean-Marc; Fejzo, Zoran

AES Convention 131 · Paper 8463 · October 2011

Abstract

We propose a flexible and practical end-to-end solution for creating, encoding, transmitting, decoding and reproducing spatial audio soundtracks. The soundtrack encoding format is compatible with legacy surround-sound decoders, while enabling the representation of a three-dimensional audio scene, irrespective of the listener’s playback system configuration. It allows for encoding one or more selected audio objects that can be rendered with optimal fidelity and interactively in any target spatial audio format (existing or future). The transmission or storage data rate and the decoder complexity are scalable at delivery time. A 3-D audio soundtrack may thus be produced once and transmitted or broadcast and reproduced as faithfully as possible on the broadest range of target devices.
