Abstract
The audio signal coding method involves transforming the audio signal into a frequency range, in order to provide a number of spectral values. A prediction method is used to provide spectral residual values, with subsequent detection of the noise regions for the residual values and noise substitution. The information for the noise regions and the noise substitutions is inserted in the side information of the coded audio signal, e.g. via a bit stream multiplexer (208), with corresponding extraction of this information at the audio signal reception point. USE - For coded audio signal transmission. ADVANTAGE - Enhances coding efficiency.
