Title:
AUDIO SEGMENTS ANALYSIS TO DETERMINE DANCEABILITY OF A MUSIC AND FOR VIDEO AND PICTURES SYNCHRONISATON TO THE MUSIC.
Document Type and Number:
WIPO Patent Application WO/2015/114216
Kind Code:
A3
Abstract:
A technique for audio processing that comprises obtaining four types of features descriptive of characteristics of a segment of audio signal representing a piece of music and, based on these features, deriving a "club score" that is indicative of at least beat strength associated with said segment of audio signal, thus describing a "danceablility" of music. An application comprises obtaining one or more audio attributes characterizing a segment of audio signal representing the piece of music, calculating a club score, and selecting a switching pattern from a plurality of predetermined switching patterns based on the club score, wherein a switching pattern is arranged to indicate discontinuities, or temporal positions and/or frequency of changes of video sources or image, in a visual content associated with said segment of audio signal, in relation to temporal locations of beats or downbeats identified for the segment of audio signal, for example for generating a visual presentation to accompany remixed music, synchronised to the music.
