Abstract
A method and an apparatus for adjusting a channel delay parameter of a multi-channel signal are provided in the embodiments of the present invention. The method includes: performing down-mixing processing on a multi-channel signal to obtain a processed signal (); calculating energy distribution of the processed signal (); and judging whether a comb filtering effect occurs in the processed signal according to the energy distribution of the processed signal, and adjusting a channel delay parameter of the multi-channel signal if the comb filtering effect occurs in the processed signal ().
