Abstract: A stereo sound decoding apparatus wherein lost-frame compensation performance has been improved to enhance the quality of decoded sounds. In this stereo sound decoding apparatus, a sound decoding part (110) uses encoded monophonic signal data and encoded side signal data, which are received from a sound encoding apparatus, to generate monophonic decoded signals and stereo decoded signals; a compensation signal switching determining part (104) that compares an inter-channel correlation and an intra-channel correlation, which have been calculated by use of the monophonic decoded signals of a previous frame and the stereo decoded signals of the previous frame, with respective comparison thresholds; a compensation signal switching part (107) that selects, based on a result of the comparison in the compensation signal switching determining part (104), as compensation signals either inter-channel compensation signals generated by an inter-channel compensating part (105) or intra-channel compensation signals generated by an intra-channel compensating part (106); and an output signal switching part (130) that outputs either the stereo decoded signals or the compensation signals according to whether the encoded side signal data of the current frame has been lost.

Abstract: The conventional error conceal processing generates a greatly fluctuating irregular sound which is unpleasant to ears and causes a remarkable echo effect and click noise. A notification signal detection unit (301) judges processing for an input frame. In case of an error frame, a sound detection unit (303) makes judgment whether a preceding non-error data frame is a sound signal. If it is a sound frame, a sound copying unit (304) generates a replacing frame. If it is a non-sound frame, a transient signal detection unit (305) judges whether it is an attack signal by the transient signal detection and selects an appropriate area from the preceding non-error frame.
