Abstract
The coding method has the stereo audio spectral values grouped into scale factor bands (28), with formation of sections each containing at least one scale factor band. The audio spectral values are coded within each section using a coding table selected from a number of coding tables. Each coding table is identified by a coding table number transmitted alongside the coded stereo audio spectral values. An additional coding table number is transmitted for an intensity stereo coding method, or an adaptive Huffman coding method for the stereo audio spectral values. ADVANTAGE - Provides compression of audio digital signals without quality degradation.
