Abstract

A method is presented for improving current coding efficiency in DSD signals. The goal of this work is to explore new compression techniques which are tailored to the DSD format and which are meant to complement the current lossless DST compression practice used for SACD. The new technique builds on principles illustrated in previous papers. The method makes use of the highly oversampled character of DSD. Example implementations and results have been obtained. Losses to stability and signal-to-noise ratio have been measured and their audio effects have been minimised and quantified. Lower bounds are established on the compression ratio of these methods. This is viewed as a first step for a potentially constant bitrate compression scheme.
