Embodiment Construction
[0074] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0075] Please refer to figure 1 , which shows a method flow chart of a method for estimating a time delay of a sound signal provided by an embodiment of the present invention. Examples are given in electronic equipment. The delay estimation method may include the following steps:
[0076] Step 102, acquiring two channels of sound signals.
[0077] Step 104, perform coherence matching on the two-way sound signals according to the short-time Fourier transform of the two-way sound signals to obtain a first matching result, the first matching result includes the first matching position and the first matching degree of the two-way sound signals .
[0078] Step 106: Perform coherence matching on the two-way sound signals according to the interspec...
