Ultra High-Resolution Audio Formats for Mastering Applications

Authors: Hawksford, Malcolm J.

Abstract

To process audio signals prior to DSD and LPCM delivery, an audio data format is required that possesses a resolution substantially greater than the final release form. A number of strategies are presented capable of enhanced resolution. Techniques using the step-back algorithm are extended to include a multi-level quantizer but where the amplitude range is finite. An earlier scheme based upon multilevel SDM and multi-stage loss-less differential coding is enhanced by incorporating more aggressive noise shaping implemented by means of parametric noise shaping previously used for binary SDM.
