Frame error concealment method and apparatus, and audio decoding method and apparatus |
摘要 |
Disclosed are a frame error concealment method and apparatus and an audio decoding method and apparatus. The frame error concealment (FEC) method includes: selecting an FEC mode based on at least one of a state of at least one frame and a phase matching flag, with regard to a time domain signal generated after time-frequency inverse transform processing; and performing corresponding time domain error concealment processing on the current frame based on the selected FEC mode, wherein the current frame is an error frame or the current frame is a normal frame when the previous frame is an error frame. |

1. A frame error concealment method comprising:
when a frame is classified as a current error frame or a next good frame after an error frame, selecting one mode from among a plurality of modes including a first mode using phase matching and a second mode using repetition and smoothing, based on a plurality of parameters including stationarity of the frame; and performing a corresponding time domain error concealment processing on the frame based on the selected mode. |
