METHOD AND APPARATUS FOR CONCEALING FRAME ERROR AND METHOD AND APPARATUS FOR AUDIO DECODING

摘要

A method for concealing a frame error comprises: a step of selecting an FEC mode based on the state of the current frame and the state of the frame prior to the current frame in the time domain signal generated after a time-frequency inverse transform process; and a step of performing, based on the selected FEC mode, a time domain error concealing process corresponding to the current frame which is an error frame or to the current frame which is a normal frame with a prior error frame.
