Title:
DIRECTIONAL SOUND PICKUP METHOD, RECORDING DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/252886
Kind Code:
A1
Abstract:
A directional sound pickup method, a recording device and a storage medium, the method comprising: acquiring a plurality of collected target sounds and a directional sound pickup instruction inputted by a user, and performing delay compensation on the plurality of target sounds so that the timing of the plurality of target sounds is the same (S10); and using a target sound among the plurality of target sounds that corresponds to the directional sound pickup instruction as a specified sound, and performing noise reduction on the specified sound (S20). When a recording device picks up sounds, delay compensation is performed on recorded sounds from all directions, then a sound in a user-specified direction is accurately picked up, and noise reduction processing is performed on noise in the picked up sound, thereby reducing the interference of sounds in the non-specified directions on a recording result so that the directional sound pickup of the recording device achieves an optimal effect.
