Abstract: |
This invention belongs to sound codes anti-signal error technique, which is characterized by the following: using the variable property on decoding end to test and restore the gains parameters error under different blur transfer modes to avoid error diffusion, under situation of next frame error codes restoring, this frame gains error codes shall not use next gain difference value statistics property besides, through computation central total one mode to estimate sound total energy level. |
