Title:
DIRECTIONAL SOUND RECORDING DEVICE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/076387
Kind Code:
A1
Abstract:
A directional sound recording device and an electronic device, which relate to the field of audio and video processing and can accurately determine the direction and the position of a sound source in a three-dimensional space, so as to pick up a sound signal in an expected sound recording range, thereby greatly improving the matching degree between the sound signal and the expected sound recording range and implementing more accurate directional sound recording. The method comprises: an electronic device determines preset sound recording ranges, the preset sound recording ranges comprising a horizontal angle range and a pitch angle range (101); the electronic device obtains a sound signal collected by a microphone array (102); the electronic device determines direction and position information of a sound source of the sound signal, the direction and position information comprising a horizontal angle of the sound source and a pitch angle of the sound source (103); the electronic device determines whether the sound source falls within the preset sound recording ranges according to the direction and position information of the sound source (104); if the sound source does not fall within the preset sound recording ranges, eliminating the sound signal (105); and if the sound source falls within the preset sound recording ranges, storing the sound signal (106).
