Embodiments of the present invention provide an audio climax recognition method and device. The method comprises: performing word segmentation on the words of the target song, and marking the time period in which the high-frequency words appear as the high-frequency word period; cutting the music of the target song into multiple slices of equal duration; performing fast Fusion on each slice respectively. Lie transform to obtain the highest frequency domain energy value of each slice; sequentially connect the frequency domain energy highest value of each slice in time sequence to obtain a slice function curve of the frequency domain energy maximum value of the slice in time; The time period in which the high-frequency word period coincides with the peak section of the slice function curve is taken as the climax period. The method and device have high precision, wide application range and save a lot of human resources.
Description
technical field [0001] The invention relates to the field of song audio processing, in particular to a method and device for identifying the climax part of karaoke. Background technique [0002] Most of the methods used in the prior art to identify the climax part of a song are to search according to the lyrics. Since the climax part of the song generally has a re-singing situation, the climax part of the song is located by this method. [0003] In the process of realizing the present invention, the inventor has found that there are at least the following problems in the prior art: the search range of the song climax part identification method in the prior art is very limited, and the accuracy of the identification method for the song climax part in the prior art is low, which is not applicable. The range is small, and the recognized climax part is difficult to perform other operations, such as making song mixes. The song climax recognition method in the prior art is time-c...
