A new digital audio recording and reproduction system based on a nonuniform sampling delta modulation (NSDM) technique is presented. Theoretical analysis and experimental results have shown that the NSDM technique has a higher coding efficiency, a larger signal-to-quantization-noise ratio and wider dynamic range than those of conventional linear delta modulation (LDM).
