Abstract

The invention relates to an audio adjusting method and device. The invention relates to an audio and video acquisition technology, and solves the problem of improving audio quality. The method comprises the following steps: acquiring a gain amplitude of a recorded audio on a camera interface; and calling an enhancement algorithm through the audio hardware abstraction layer, and adjusting the gain of the acquired audio data in real time according to the gain amplitude. The technical scheme provided by the invention is suitable for the real-time adjustment of the uplink audio data, and realizes the flexible adjustment of the audio gain according to the environment and user demands.

Description

technical field [0001] The present disclosure relates to audio and video capture technologies, and in particular, to an audio adjustment method and device. Background technique [0002] As the use of mobile terminals such as mobile phones in video shooting becomes more and more popular, users' requirements for shooting quality are also increasing. In the process of video recording, due to the complex application environment and most of the shooting in a mobile state, the audio capture is greatly affected by the environment. How to obtain higher quality audio is an urgent problem to be solved. [0003] For the Qualcomm platform, the camera application can call the cam_karaok_set_parameters() function to pass the parameters to the audio hardware abstraction layer (AudioHal). These ids are sent to the sound control module together with the gain parameters, and the gain adjustment is realized in the sound control module. [0004] However, for platforms such as MediaTek, the Qu...
