-- AUDIO DECODER METHOD AND COMPUTER PROGRAM USING A ZERO-INPUT-RESPONSE TO OBTAIN A SMOOTH TRANSITION

摘要

An audio decoder, method and computer program using a zero input response to obtain smooth transitions. An audio decoder (100; 200; 300) for providing decoded audio information (112; 212; 312) based on encoded audio information (110; 210; 310) A linear prediction domain decoder (120; 220; 320) configured to provide a first decoded audio information (122; 222; 322; S _C (n) A frequency domain decoder 130 (230; 330) configured to provide two decoded audio information 132 (232; 332; S _M (n)), and a transition processor 140 (240; The transition processor is configured to obtain a zero input response (150; 256; 348) of the linear prediction filtering unit (148; 254; 346), wherein the initial state of the linear predictive filtering (146; 252; 344) Audio information and second decoded audio information. The transition processor also includes a second decoded audio information (132; 232; 332; S _{M) that is} provided based on an audio frame encoded in the frequency domain following the audio frame encoded in the linear prediction domain, (n).
