Abstract

As compression rates for audio signals approach the 1 bit/sample/Hz threshold, the applicability of parametric spectral modeling techniques is of increasing interest. This paper reports continued work in this area, in developing further the technique of adaptive predictive coding with transform domain quantization (APC-TQ). In particular, improvements in the efficiency of representation of the signal spectrum representation of the modeling of harmonic structure are addressed
