Abstract
An apparatus for decoding a compressed and coded sound signal by applying thereto an inverse quantization processing and a synthesis processing is arranged to include a data extracting unit for extracting quantization level data, scale factor data and quantization data from a data stream of the compressed and coded sound signal, and an integrated processing unit for processing the extracted data by use of an integrated operational equation which is obtained by combining a first operational equation used for the inverse quantization processing with a second operational equation used for the synthesis processing.
