METHOD AND APPARATUS FOR PROCESSING AUDIO SIGNALS

摘要

Disclosed is a method for processing audio signals. The method comprises the steps of: receiving long-term prediction information and a residual; performing an inverse-frequency-conversion for the residual to generate a synthetic residual; and performing a long-term synthesis based on the synthetic residual and the long-term prediction information to generate the synthetic audio signal of a current frame. The long-term prediction information includes the final gain and the final delay. The range of the final delay starts at 0, and the long-term synthesis is performed based on the synthetic audio signals of the frames including previous frames.
