Abstract

The invention discloses a song audio frequency cutting apparatus and a method thereof. The method comprises the following steps: acquiring a lyrics text file of a song audio frequency file; analyzing a repetition degree of every line of the lyrics in the lyrics text file and adding the repeated lyrics whose repetition degree is higher than a specific threshold in a candidate set; analyzing the repeated lyrics in the candidate set, acquiring a distribution position and making several lines of the continuously distributed repeated lyrics form a paragraph; according to the repetition degree of the each line of the repeated lyrics and the position in the paragraph, determining one line of the repeated lyrics as initial cutting lyrics and taking a starting time point of the initial cutting lyrics as an cutting starting point of the song audio frequency file; using a song cutting device to cut the song audio frequency file from the cutting starting point. By using the apparatus and the method of the invention, a climax part of the song audio frequency file can be automatically identified in batch and cut so that an accuracy of song climax identification can be guaranteed.
