Title:
METHOD AND APPARATUS FOR DETERMINING ORIENTATION OF SOUND SOURCE, STORAGE MEDIUM, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/246224
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of microphones, and provides a method and apparatus for determining the orientation of a sound source, a storage medium, and an electronic apparatus. The method for determining the orientation of a sound source comprises: when determining that two adjacent microphone elements in a microphone array receive an incident sound wave emitted by a sound source, determining a time delay value for the incident sound wave to reach the two adjacent microphone elements; performing frequency modulation conversion on a cross-power spectrum of the incident sound wave according to the time delay value so as to obtain a time delay spectrum function of the incident sound wave; according to the time delay spectrum function, determining a sound wave incident angle of the incident sound wave relative to the microphone array, and determining the orientation of the sound source relative to the microphone array according to the sound source incident angle.
