Abstract

The invention provides an audio file processing method and device. The method includes: acquiring a first sound spectrogram and a second sound spectrogram corresponding to a first audio file and a second audio file respectively, which are related audio files; acquiring offset time of the first audio file and offset time of the second audio file through the first sound spectrogram and the second sound spectrogram; correlating the first audio file and the second audio file through the migration times. The audio file processing method and device according to the embodiment has the advantages that two audio files can be seamlessly switched through the offset times, and entertainment experience is improved for users.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a method and device for processing audio files. Background technique [0002] With the increasing entertainment needs of people, Internet operators are also providing K song services to users in the form of network K karaoke rooms. There will be asynchronous phenomena when switching, so it is necessary to synchronize the accompaniment tape with the original singing. If the user cannot switch to the original song instantaneously when the user needs to listen to the original song, the two audio signals cannot be fully aligned due to the switch, thereby reducing the user's entertainment experience. Contents of the invention [0003] Embodiments of the present invention provide a method and device for processing an audio file, so that a user can realize seamless switching between two audio files as required, thereby improving the user's entertainment experience. [0004]...
