Abstract

For Spectral Oriented Trees (SOT) based coders such as SPIHT and CEIHT, locality is usually related to the locations of coefficients within a SOT and its effect to coding efficiency. How to construct a SOT to achieve better locality is very important. This paper presents a diagnostic aspect of the localities of different ordering techniques for low bit-rate audio coding. We used several coefficient ordering schemes to construct SOTs with the same set of MDCT coefficients and observed their effects. Both objective and subjective results are presented.
