AUDIO SIGNAL PROCESSING METHOD AND DEVICE

摘要

PURPOSE: An audio signal processing method and a device thereof are provided to minimize propagation of errors to a next frame. CONSTITUTION: An audio signal is received wherein the audio signal includes current frame(S100). An error occurs in data of the current frame(S300). Frame error concealment about data of the current frame is performed. A first provisional output signal of the current frame is generated(S400). A parameter is generated by performing at least one of short term prediction, long term prediction, and fixed codebook search(S500). [Reference numerals] (S100) Receiving an audio signal including current frame data; (S200) Checking generation of an error; (S300) Error has occurred?; (S400) Generating a temporary output signal by performing error concealment; (S500) Re-encoding the temporary output signal; (S600) Transferring encoded parameters to a decoding unit; (S700) Decoding the current frame
