Abstract

The present invention relates to an audio generating method. The method comprises the following steps: performing theme extraction on comparison audio to obtain a comparison note sequence, wherein the comparison note sequence comprises a comparison note position, a comparison note pitch and a comparison note duration; obtaining original audio matched with the comparison audio by audio retrieval, and obtaining an original note sequence corresponding to the original audio, wherein the original note sequence is obtained by performing theme extraction on the original audio and comprises an original note position, an original note pitch and an original note duration; calculating a theme distance between segments of the comparison audio and the original audio according to the comparison note sequence and the original note sequence; and intercepting the segments of the original audio with the minimum theme distance as the generated audio. The segments of the original audio require no manual pickup, a user only needs to upload the comparison audio, so that the operation is convenient, and the intercepted segments are accurate. In addition, the invention further provides an audio generating device.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to an audio generation method and device. Background technique [0002] With the development of computer technology and digital multimedia, people download multimedia music through the network, and make their favorite music fragments as ringtones. [0003] The existing method of intercepting music fragments has a high threshold. It is necessary to retrieve the music to be intercepted first, and then use professional audio interception software to determine the interception start point and end point by dragging. If the user does not remember the song title or lyrics, the music to be intercepted cannot be retrieved, and it is difficult to accurately determine the starting point and the ending point of the melody by hearing. This method of generating audio has many complicated steps. Contents of the invention [0004] Based on this, it is necessary to provide an audio generation m...
