Abstract

The invention relates to a sound recording method and device and belongs to the field of audio and video processing. The method comprises the steps that during video shooting, a sound recording direction set by a user is received through a touch screen; a directional sound recording parameter corresponding to the sound recording direction is obtained; and sound data in the sound recording direction are recorded through a microphone array via the directional sound recording parameter. Only the sound data in the sound recording direction are recorded, the problem that sound data collected by an internal microphone are always mixed with the sound which the user wishes to record and environment noise, and the sound quality of a shot short video is poor is solved, the effect that only the sound which the user wishes to record is recorded is achieved, the sound quality of the shot short video is improved, and user experience is improved.

Description

technical field [0001] The present disclosure relates to the field of audio and video processing, in particular to a recording method and device. Background technique [0002] Using a mobile terminal such as a smart phone, a tablet computer, or an e-book reader to shoot video is one of the most frequently used functions by users. [0003] Taking the use of a smart phone to shoot a short video as an example, the user can use the rear camera of the smart phone to collect image data, and use the built-in microphone of the smart phone to collect sound data in the environment. [0004] During the process of implementing the present disclosure, the discloser found that the above method has at least the following defects: due to the complex and changeable environmental conditions when shooting short films, the sound data collected by the built-in microphone is often mixed with the sound that the user wants to record and environmental noise. The sound quality of the resulting clip ...
