Title:
STEREOPHONIC CODING METHOD AND STEREOPHONIC CODER
Document Type and Number:
WIPO Patent Application WO/2018/121386
Kind Code:
A1
Abstract:
A stereophonic coding method and a stereophonic coder. When stereophonic coding is performed, a sound track combination coding scheme of the current frame is determined first, and then a quantified sound track combination scale factor of the current frame and a coding index of the quantified sound track combination scale factor are obtained according to the determined sound track combination coding scheme, thereby enabling an obtained main sound track signal and secondary sound track signal of the current frame to conform to the characteristic of the current frame, ensuring the smoothness of a sound image of a coded composite stereophonic audio signal, reducing a drift phenomenon, and improving the coding quality.
