Abstract

The invention relates to a method of iterative coding and an iterative coding device. When iterative coding is performed, the channel-coherent coding solution of the current frame is predetermined, and then the quantized channel-coherent ratio of the current frame and the coding index of the quantized channel-coherent ratio are obtained based on the determined channel-coherent coding solution, such that the primary and secondary channel signals of the current frame are obtained to satisfy the characteristics of the current frame. It is ensured that the audio image of the synthesized repeating audio signal obtained after encoding is stable, audio slip is reduced, and encoding quality is improved.
