Abstract: Encoding and decoding of residual signals are provided. In a method of encoding a residual signal of an audio signal, the residual signal is divided into a plurality of sections having different sizes, based on a change of the residual signal. Then, section division information representing information about the divided sections and section-by-section residual signal information representing characteristics of the sections of the residual signal are acquired. Thereafter, the residual signal is encoded based on the section division information and the section-by-section residual signal information.

Abstract: A method of and apparatus for parametric encoding and parametric decoding are provided. According to the method and apparatus, not all parameters for all component signals are generated and according to a time interval, parameters for some component signals are replaced by index information allowing similar previous time intervals to be found, thereby increasing encoding efficiency.
