Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0028] In the embodiment of the present invention, audio files may include but not limited to: files such as songs and song fragments. An audio file includes audio data, and the audio data (for example: PCM data) can be obtained by decoding the audio file (for example: PCM decoding). The audio data of an audio file may include at least one audio frame, that is, the audio data of an audio file may be represented as a frame sequence composed of multiple audio frames ...

The embodiment of the invention provides an audio processing method, device and terminal. The method comprises the steps: obtaining audio data of a target audio file, wherein the audio data comprises at least one audio frame; building a peak characteristic sequence according to the correlation of the audio frame, wherein the peak characteristic sequence comprises at least one peak characteristic element; carrying out the ordering of the peak characteristic sequence; determining paragraph change time according to at least one peak characteristic element of the ordered peak characteristic sequence; and carrying out the division of paragraphs of the target audio file according to the paragraph change time. The method can achieve the division of paragraphs of the target audio file based on the correlation of the audio frame in the audio file, improves the efficiency of paragraph division, and improves the intelligent performance of audio processing.
Description
technical field [0001] The present invention relates to the technical field of the Internet, in particular to the technical field of audio processing, and in particular to an audio processing method, device and terminal. Background technique [0002] With the development of Internet technology, a large number of audio files such as songs and song fragments have been included in the Internet audio library, and the application of Internet audio is also increasing day by day, such as: Karaoke system, listening to songs system, etc. Many application scenarios of audio files require paragraph division of audio files. For example, when a song is to be sung in sections in a karaoke system, it is usually necessary to divide the song into paragraphs; Often the song needs to be divided into paragraphs; etc. At present, audio files are usually divided into sections manually, and the segmentation processing efficiency is low, which cannot meet the needs of users for using audio files, ...
