A new digital audio processing system based on Nonuniform Sampling Delta Mod-ulation (NSDM) technique is presented in this paper. The performance of NSDM system is analysed. Theoretical analysis and experimental results have demonstrated that the perfor-manc e of NSDM system used in digital audio is better than that of conventional Linear Delta Modulation (LDM) in terms of coding efficiency, Signal to Quantization-Noise Ratio and dy-namic range.
