Method and apparatus for estimating interchannel delay of sound signal

摘要

A method and an apparatus for estimating an interchannel delay of a sound signal are, related to the communication field and capable of realizing a stable sound field in a crosstalk. The method includes calculating an error between an actual interchannel phase difference and a predicted interchannel phase difference of a sound signal. The predicted interchannel phase difference is predicted according to a predetermined interchannel delay of the sound signal. The method also includes determining whether the sound signal is a sound signal in a crosstalk according to the error. The method further includes, if the sound signal is a sound signal in the crosstalk, setting an interchannel delay corresponding to the sound signal to a fixed value. The apparatus is configured to perform the method.

1. A method for estimating an interchannel delay of a sound signal, the method comprising:
calculating an error between an actual interchannel phase difference and a predicted interchannel phase difference of a sound signal, wherein the predicted interchannel phase difference is predicted according to a predetermined interchannel delay of the sound signal; determining whether the sound signal is a sound signal in a crosstalk according to whether the error is within a predetermined range or beyond the predetermined range, the predetermined range being set according to an interchannel delay of a sound signal that is not in the crosstalk; and if the sound signal is a sound signal in the crosstalk, setting an interchannel delay corresponding to the sound signal to a fixed value.
