Provided are an audio and video file generation method, apparatus and system. The method comprises: a voice recording device receiving clock synchronization information sent by a photographing device; the voice recording device synchronizing a clock timing start point of the voice recording device to a photographing start moment according to the clock synchronization information, and recording and storing voice data of a photographed person from the photographing start moment; and the photographing device merging the voice data with video image data into an audio and video file. In the embodiments of the present invention, voice data and video image data correspond to the same photographing start moment, i.e. being on the basis of the same time axis, and even though a photographed person is in a motion state or far away from a photographer, a voice recording device fixed on the photographed person can record and store clear voice data, thereby ensuring that the voice data and the video image data have a very high matching degree, and ensuring that a merged audio and video file has a very high voice quality. |
