METHOD FOR CODING AN AUDIO SIGNAL DIGITALIZED AT A LOW SAMPLING RATE

摘要

In a method for coding an audio signal digitalized at a low sampling rate a respective number of successive frequency lines of the digitalized audio signal which are assigned to a scale factor band are coded with the same scale factor, successive scale factor bands forming a region within which all the scale factor bands are coded with the same number of bits, which is determined according to the largest scale factor of the region. The frequency lines of at least the highest region of scale factor bands are coded with the scale factor 0. No scale factor is coded for at least the highest region.
