In this paper, we present a new approach to shape the coding noise in speech and audio coders. The approach, called Spectral Amplitude Warping (SAW), consists essentially of a preand post-processing which apply a non-linear transformation to the signal short-term spectrum prior to, and after, encoding. Since it is possible to view SAW as a separate entity from the coder, the noise shaping capability of an existing coder can be improved without modifying the coder itself. Using SAW as a preand… CONTINUE READING
