AB  - An alternative method of digitizing music signals is presented. It relies on the techniques of spectral noise shaping and oversampling, which achieve theoretical and computed signal-to-quantization-noise ratios of 110-120 dB. This encoding scheme is based on high order delta-sigma modulation and is referred to as HLDSM A/D conversion. A hardware conversion of this system was developed measuring 80-dB SQNR and 0.007% total harmonic distortion. Potentially the HLDSM A/D converter offers noise and distortion performance superior to pulse-code modulation, a simpler hardware realization and reduced cost.
