Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0054] Before explaining the embodiment of the present invention in detail, the nouns and system architecture involved in the embodiment of the present invention will be described first.

[0055] First, a brief introduction to the nouns involved in the embodiments of the present invention:

[0056] Binaural: It usually includes a left channel and a right channel. Generally, the left channel corresponds to storing the data of the accompaniment audio, and the right channel corresponds to storing the data of the original singing audio.

[0057] short-term energy algorithm : It is used to determine the alignment position of the two audios based on the energy of the two audios through the short-term energy formula.

[0058] Secondly, a...

Abstract

The invention discloses an audio synthesis method, device and storage medium, belonging to the technical field of multimedia. The method comprises: according to the song information corresponding to the accompaniment audio file to be synthesized, obtaining the target original audio file corresponding to the accompaniment audio file; If the first duration difference of the accompaniment audio file is less than or equal to the preset threshold, the alignment position of the original accompaniment is determined by the short-term energy algorithm. If the time difference is greater than the preset threshold, the alignment position of the original accompaniment is determined by the short-term cross-correlation algorithm; based on the alignment position of the original accompaniment, the accompaniment audio file and the target original audio file are merged into a complete audio file. In this way, the audio synthesis is automatically realized without manual operation, and the audio synthesis efficiency is improved.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to an audio synthesis method, device and storage medium. Background technique [0002] With the rapid development of multimedia technology, there are abundant music platforms that can provide audio files, for example, the music platform is a karaoke platform. In the karaoke platform, the basic format of a complete audio file usually needs to include two channels, a specified bit size, a specified sampling rate, etc. For example, the specified bit size can be 16bit, and the specified sampling rate can be 44100Hz. Wherein, the dual-channel corresponds to the accompaniment audio and the original singing audio respectively. In practical application scenarios, generally the accompaniment audio file and the original vocal audio file exist independently, therefore, it is usually necessary to synthesize the accompaniment audio and the original vocal audio. [0003] In related ...
