Abstract: A signal process method, used for processing the compound signal in the lost packet concealment, includes the following steps, receiving a good frame next to the lost frame, achieving the good frame information and the energy ratio of the compound signal at the receiving time of the good frame; adjusting the compound signal according to the energy ratio. A signal process device and an audio decoder are also provided. Through using the method in the present invention, the compound signal is adjusted based on the energy ratio of the first good frame behind the lost frame and the compound signal to guarantee that the compound signal does not generate waveform or energy jumping at the joint point of the lost frame and the first frame behind the lost frame to realize the smooth transition of the waveform and to avoid the musical noise.

Abstract: A method and apparatus of frame error concealment for highband signal are provided. The method comprises: computing the periodic intension of highband signal's pitch period information about lowband signal; judging whether the periodic intension is larger than or equal to the presetting threshold or not; if it is, executing the frame error concealment to highband signal of current lost frame using the method of pitch period repeating; if it is not, executing the error frame concealment to highband signal of current lost frame using the method of previous frame data repeating.

Abstract: A frame compensation method is provided, which includes the following steps: obtaining the length of a lost frame and a correct frame; judging the length of a correct frame is integral power times of two of the length of a lost frame, then obtaining the data sequence whose length is same as the length of the lost frame according to the correct frame; compensating the lost frame according to the said data sequence, obtaining the compensated data frame. A frame compensation system is also provided, which includes: a first length obtaining module, a second length obtaining module, a data sequence obtaining module and compensation module. Lost frames with various formats are compensated according to correct frames with various formats, so that the limitation of the prior art that the lost frame with single format is justly compensated according to the correct frame with single format is conquered, and the effect of the data frame after compensation is better than that of filling comfort noise.
