Audio data generation method, device and system and controller

Abstract

The embodiment of the invention provides an audio data generation method, device and system and a controller. The method comprises the following steps: generating a timestamp representing the currentrecording moment in a process of recording a video by a camera; writing the timestamp into the audio output chip to enable the audio output chip to generate time audio signals, and inputting the timeaudio signal to the camera, enabling the camera to generate time audio data representing the time audio signals, wherein the time audio data corresponds to the video recorded at the current recordingmoment; the audio signal is generated according to the timestamp, the timestamps are recorded in the audio data of the videos recorded by the camera according to the audio signals, and when the multiple videos need to be synchronized, the video synchronization points of the videos can be determined according to the timestamps recorded in the audio data, and due to the fact that each video only needs to be processed once, the synchronization efficiency of the multiple videos is improved.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to an audio data generation method, device, system and controller. Background technique [0002] In the process of recording film and television programs, multiple cameras are often required to shoot programs in different positions and scenes. For example, when recording a variety show, the first camera is responsible for shooting facing the stage and can shoot the entire process of the program. The second camera is responsible for shooting the designated star, and the third camera is responsible for capturing the wonderful moments. However, since the shooting time of each camera may be different, and some cameras may pause in the middle of the shooting, resulting in a large number of videos produced by these cameras without a unified time information, when editing and producing programs in the later stage, manual editing is required. The videos are synchronized in...

Problems solved by technology

[0005] The existing technology can only calculate two or two audio and video. When the number of videos is too large, the number of calculations required is also greatly increased, and the efficiency is low. For example: when there are 5 videos that need to be processed, the number of calculations required is When there are 10 videos that need to be processed, the number of calculations required is
