An audio real time switching method and device

Abstract

Embodiments of the invention provide an audio real time switching method and device. The method includes: decoding multitrack original singer audio frequency coding files and accompaniment audio frequency coding files, obtaining multitrack original singer audio frequency data and corresponding accompaniment audio frequency data, adding the multitrack original singer audio frequency data and corresponding accompaniment audio frequency data to a first data queue and second data queue which are arranged in sequence, playing the accompaniment audio frequency data extracted from the second data queue according to the switching operation, switching to play the original singer audio frequency data extracted in the corresponding position from the first data. The real time switching from playing accompaniment to original singer is realized, as the multitrack original singer and accompaniment are respectively stored to the multitrack original singer audio frequency coding files and accompanimentaudio frequency coding files, therefore whether the original singer and accompaniment are both multitrack, and the real time switching and the sound effects of the original singer and accompaniment are realized at the same time.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio real-time switching method and device. Background technique [0002] In the singing application, the user only listens to the accompaniment to sing, and it is easy to get out of tune or fail to keep up with the rhythm. At this time, the user needs to listen to the original singing and the recorded work is a composite of his own vocals and accompaniment. [0003] In order to realize the real-time switching between the original singing and the accompanying singing, the existing technology stores the original singing as a channel and the accompanying singing as a channel in an audio file, and realizes the switching between the original singing and the accompanying singing by switching the channels during playback. Therefore, both the original singing and the accompanying singing are monophonic, and the sound effect is not good. Moreover, the final synthesized audi...

Problems solved by technology

[0003] In the existing technology, in order to realize the real-time switching between the original singing and the accompanying singing, the original singing is stored as a channel in an audio file, and the accompanying singing is stored as a channel, and the original singing and the accompanying singing are realized by switching channels during playback. Therefore, both the original singing and the accompanying singing are monophonic, and the sound effect is not good

Moreover, the final synthesized audio is also synthesized from the recorded user audio and monophonic accompaniment, resulting in the accompaniment in the synthesized audio is also monophonic, that is, the synthesized user works have a poor sound effect
