The invention discloses a method and system for simultaneously recording near-field audio and far-field video. The method includes: setting a volume threshold and a time threshold; receiving a voice control signal for enabling recording; receiving audio information at the current moment in real time; judging the time threshold received Whether the audio information at the current moment is greater than the set volume threshold; if so, receive the audio information at the next moment recorded by the audio capture device and the video information recorded by the video capture device in real time; otherwise continue to judge whether the audio information at the current moment is greater than the set volume Threshold; update the audio information at the current moment in real time; judge in real time whether the audio information at the current moment received in real time within the time threshold is less than the set volume threshold; if so, stop receiving the audio information and video information at the next moment; otherwise continue to receive. Using the above method or system can simultaneously record near-field audio and far-field video at the same scene position and at the same time period, and start and end recording by voice control.
Description
technical field [0001] The invention relates to the field of audio and video recording, in particular to a method and system for simultaneously recording near-field audio and far-field video. Background technique [0002] At present, the method of receiving audio and video data is basically by using software for recording audio and software for recording video. Some software for recording video has a built-in function of recording audio. When recording video through a camera with a built-in microphone, audio is also recorded. But there is no software that records far-field video through a camera at the same time as near-field audio through a microphone. Moreover, many existing audio recording software cannot start recording through voice control, but through the functions of one-key recording and timing recording. The one-key recording function needs to trigger recording, which will bring inconvenience to specific workplaces. The timing recording function requires Setting t...
