Abstract

The embodiment of the invention discloses an audio signal processing method and a terminal. According to the method, at least one frame of audio data acquired by a media playing interface and a real-time audio signal from audio input equipment are mixed in real time; and the media playing interface acquires the audio file by taking the frame as a unit, instead of acquiring the whole audio file, sothat the audio file can be flexibly switched to any frame of audio data of other audio files at any time through the media playing interface in the audio mixing process. A data path in system software is used for transmitting at least one frame of audio data, and the external environment noise is not introduced. In addition, an audio detection mechanism is introduced into the method, the volume of at least one frame of audio data participating in audio mixing can be adaptively adjusted, and the audio mixing experience is improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for processing audio signals. Background technique [0002] With the continuous development of mobile communication services and Internet services, more and more users tend to use short voice, small video and live online video to record or share the details of life. Among them, live online video is more intuitive because of its , fast, interactive and other advantages and widely loved by Internet users. [0003] In some audio recording scenarios, in order to obtain audio or video files with specific effects, it is necessary to mix user-specified background music into the collected voice files through sound mixing technology, or to mix specific The accompaniment or song is inserted into the recorded video. In the existing sound mixing technology, whether it is analog sound mixing or digital sound mixing, it is impossible to adjust and modify the backgr...
