Abstract

The invention discloses a method and a device for dragging an audio file to retrieve audio file information. The method includes that detecting a dragging operation on the audio file; acquiring an audio signal of the audio file according to the dragging operation; carrying out a framing treatment on the audio signal to generate at least one audio sub-frame; using a starting point detection algorithm (ODF) to determine a key frame in the at least one audio sub-frame; extracting audio fingerprint of the key frame; using the audio fingerprint to retrieve in an audio fingerprint database to obtain audio file information corresponding to the audio fingerprint. The method and the device for dragging the audio file to retrieve the audio file information can achieve retrieving without character input and also can shorten the information input time when retrieving.

Description

technical field [0001] The invention relates to audio processing technology, in particular to a method and device for dragging and dropping audio files to retrieve audio file information. Background technique [0002] Existing audio files (such as song files) are searched by manually inputting text information such as the title of the audio file, the songwriter of the audio file, the deduction of the audio file (such as a singer) or the name of the music album. Yet if the user locally has such a song file, its file information has been destroyed, there is no song name or singer name or album name, at this moment, by existing search method, the user is difficult to check the true information of this song, Download the lyrics for this song, or find the same song in higher quality, etc. Moreover, even if you know the song name, singer name, album name and other information of this song, the user's manual input is too troublesome and error-prone, and there are often many search...
