WIPO Patent Application WO/2010/121536
Kind Code:
A1
Abstract:
A method and apparatus for correcting channel delay parameters of a multi-channel signal are provided. The method involves: performing a down-mixing process on the multi-channel signal to acquire a processed signal (101), calculating energy distribution of the processed signal (102), and judging whether a comb filtering effect occurs in the processed signal according to the energy distribution of the processed signal, if the comb filtering effect occurs, correcting the channel delay parameters of the multi-channel signal (103).
