Abstract: An electronic device plays, by using a first application, audio corresponding to a first media file, and displays a video recording interface of a second application; in response to an operation on a background music setting option, the electronic device sets background music as audio corresponding to a second audio file; in response to a first operation on a virtual button, the electronic device starts video recording, and processes the second audio file to obtain audio data of the second audio file; and in response to a second operation on the virtual button, the electronic device ends video recording, and generates a video file, where the video file includes the audio data of the second audio file and image data of an image captured by a camera, but does not include audio data of the first media file.

Abstract: A first audio timestamp of first audio is corrected based on a first latency corresponding to the first audio, to correct a correspondence between the first audio timestamp, the first audio, and a first image. In this way, a stored correspondence between the first image and the first audio is consistent with a correspondence between a picture corresponding to the first image and a sound corresponding to the first audio, thereby implementing audio and image synchronization.

Abstract: An example method is discussed, which includes determining first audio data. The example method further includes determining a text file and metadata of the first audio data by performing content recognition processing on the first audio data. The example method further includes determining an audio type of the first audio data by performing audio type recognition processing on the first audio data based on the text file and the metadata. The example method further includes determining a sound effect mode corresponding to the audio type, where the sound effect mode is determined based on a preset correspondence between the audio type and the sound effect mode. The method further includes playing the first audio data based on the sound effect mode.
