MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202418068898 A) filed by Huawei Technologies Co. , Ltd. on September 11, 2024, for Delay Estimation Method And Apparatus.
Inventors include Shlomot, Eyal; Li, Haiting Number; and Miao, Lei.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: This application discloses a delay estimation method and apparatus, and belongs to the audio processing field. The method includes: determining a cross-correlation 5 coefficient of a multi-channel signal of a current frame; determining a delay track estimation value of the current frame based on buffered inter-channel time difference information of at least one past frame; determining an adaptive window function of the current frame; performing weighting on the cross-correlation coefficient based on the delay track estimation value of the current frame and the adaptive window function of 10 the current frame, to obtain a weighted cross-correlation coefficient; and determining an inter-channel time difference of the current frame based on the weighted crosscorrelation coefficient, so as to resolve a problem that the cross-correlation coefficient is excessively smoothed or insufficiently smoothed, thereby improving accuracy of estimating an inter-channel time difference.
