Document Type and Number:
WIPO Patent Application WO/2018/209942
Kind Code:
A1
Abstract:
Provided are a method and device for processing a stereo signal. The method comprises: performing delay estimation on a stereo signal of a current frame to determine an inter-channel time difference of the current frame, the inter-channel time difference of the current frame being a time difference between a first audio channel signal and a second audio channel signal of the current frame; and if a symbol of the inter-channel time difference of the current frame is different from a symbol of an inter-channel time difference of a frame preceding the current frame, performing, according to the inter-channel time difference of the current frame, delay aligning on the first audio channel signal of the current frame, and performing, according to the inter-channel time difference of the preceding frame, delay aligning on the second audio channel signal of the current frame, the first audio channel signal being a target audio channel signal of the current frame, and the second audio channel signal being in the same audio channel as a target audio channel signal of the preceding frame.
