Abstract

Spatially Squeezed Surround Audio Coding (S³AC) was introduced as an approach to multi-channel audio compression which specifically aims to preserve original source localization information. In this paper, extensions to S³AC that allow for the accurate coding of independent spatial sources overlapped in both frequency and time are described; these use compact side information. An evaluation of the coder applied to tone and band-pass spatial sources shows that S³AC offers improved source localization performance while maintaining bit-rates, when compared with other state-of-the-art spatial audio coders.
