Frame loss recovery method, and an audio decoding method and apparatus using the same

Recovery method, an audio decoding method and apparatus using the method according to the present invention relates to frame loss. A method according to the present invention is the recovery of the missing frame audio signal, comprising: at least a previous frame among the transform coefficients of the current frame is a frame of the packet is a predetermined number of tape; decay constant is derived in accordance with the pitch; and by the attenuation constant to the current frame the previous frame, transform coefficients of the current frame is restored.
