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. © Springer-Verlag Berlin Heidelberg 2007.
