技术领域technical field
本发明实施例涉及音频处理技术领域，尤其涉及一种清唱歌曲拼接的方法及装置。The embodiments of the present invention relate to the technical field of audio processing, in particular to a method and device for splicing a cappella songs.
背景技术Background technique
随着移动互联网技术的快速发展，装置(如手机、平板电脑、touch)及专用播放机等对音乐的追求也越来越来。目前来看，现有技术中对音乐的功能播放仅限于提高自身的音质处理，如通过装置或者专用播放机中自带的处理软件对劣质音频文件进行适当处理，以提高播放质量；或者，对音频文件本身的质量要求较高，往往正版音频文件能播出较好的效果，而对音频文件的局部处理，如切割技术、提取技术研究较少。With the rapid development of mobile Internet technology, devices (such as mobile phones, tablet computers, touches) and dedicated players are increasingly pursuing music. At present, the functional playback of music in the prior art is limited to improving its own sound quality processing, such as properly processing low-quality audio files through the processing software that comes with the device or a dedicated player to improve the playback quality; The quality requirements of the audio file itself are relatively high, and often genuine audio files can play better results, but there is little research on the partial processing of audio files, such as cutting technology and extraction technology.
现有技术中，有对歌曲进行切割以实现高潮部分提取，但往往借助于网络软件，这种方式定位十分繁琐，且需要人为判断歌曲的高潮部分，如果针对大量歌曲的处理，效率就更低了。In the prior art, some songs are cut to extract the climax part, but often with the help of network software, this method of positioning is very cumbersome and requires human judgment on the climax part of the song. If it is for a large number of songs, the efficiency will be lower up.
