ABSTRACT:
In a method and apparatus to conceal an error in an audio signal, when the current frame has no error and a past frame input prior to the current frame has an error, a parameter for the past frame is generated using a parameter for the current frame and a parameter of a frame out of frames input prior to the past frame and a previously stored parameter is updated with the generated parameter, thereby concealing an error of an audio signal without additional delay and preventing degradation in sound quality in a frame that is input after a frame having an error.
