Embodiment Construction

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

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

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

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

[0057] Short-term energy algorithm : Used to determine the alignment position of the two tones based on the energy of the two tones through a short-term energy formula.

[0058] Secondly, the system architecture involved in the embodime...

Abstract

The present invention discloses an audio synthesis method and device, and a storage medium, belonging to the multimedia technology field. The method comprises: acquiring a target original audio file corresponding to an accompaniment audio file according to song information corresponding to the accompaniment audio file to be synthesized; if a first duration difference between an accompaniment audioduration of the accompaniment audio file and an original audio duration of the target original audio file is smaller than or equal to a preset threshold, determining an accompaniment original alignment position through a short-time energy algorithm, and if the first duration difference between the accompaniment audio duration of the accompaniment audio file and the original audio duration of thetarget original audio file is larger than the preset threshold, determining an accompaniment original alignment position through the short-time energy algorithm; and based on the accompaniment original alignment position, combining the accompaniment audio file and the target original audio file into a complete audio file according to an assigned audio file format. Therefore, the audio synthesis method and device, and the storage medium can realize audio synthesis and do not need manual operation so as to improve audio synthesis efficiency.

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, a rich music platform has emerged that can provide audio files. For example, the music platform is a K song platform. In the K song 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. Among them, the two channels correspond to the accompaniment audio and the original singing audio respectively. In actual application scenarios, the general 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 technologies...
