An embodiment of the invention provides a sound pickup method and a system thereof, wherein the method comprises the steps of acquiring the position and the direction of a sound source according to asound signal which is acquired by a microphone array; identifying the sound source according to the position of the sound source, and determining an output channel of the sound signal according to anidentification result; acquiring a to-be-output signal according to the sound signal which is acquired by the microphone array, enhancing the to-be-output signal according to the direction of the sound source, and outputting the enhanced to-be-output signal through the output channel. According to the sound pickup method and the system provided by the embodiment of the invention, the output channel of the sound signal is determined through the acquired position of the sound source, and furthermore the sound signal is enhanced according to the direction of the sound source; the enhanced sound signal is output through the corresponding output channel; the sound source can be effectively separated through a sound pickup; separated pickup and outputting of multiple sound sources are more simply and conveniently realized; and furthermore sound pickup efficiency, sound pickup result and sound quality are improved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of audio signal processing, and in particular, to a sound pickup method and system. Background technique [0002] The acquisition and enhancement of acoustic signals (especially voice signals) is an important technical basis for industries including smart home, vehicle navigation, monitoring, teleconferencing, and remote collaboration. Acoustic front-end processing equipment needs to optimize the signal algorithm and array structure to realize the following functions at the software and hardware levels: hands-free technology; acquisition, encoding, transmission and playback of high-fidelity voice signals; Sound, echo and interference processing; positioning and separation of sound sources, etc. [0003] In the sound pickup environments such as interviews, interrogations, and round table conferences, the existing technology uses a pickup or multiple near-field microphones to pick up...
