DSD Compression for Recent Ultra High Quality 1-bit Coders
This paper gives a high level introduction to the lossless DSD compression algorithm, used within the context of Super Audio CD, and currently in the process of MPEG standardization. Measurement results on various commercially available discs are shown and the achievable disc playing time is illustrated. Furthermore, the flexibility of DSD is demonstrated by the introduction of a new Trellis based Sigma Delta Modulator (SDM) which is at least four times less CPU demanding than previously published Trellis SDMs. With this new Trellis coder ultra high quality SA-CD recordings, with dynamic range in excess of 115 dB and bandwidth of about 80 kHz, are achieved. Typical SA-CD playing times of over 80 minutes, even for difficult, 2+6 channel, pop material are realized.
