    摘要: A technique for audio processing is provided. According to an example embodiment, the technique comprises obtain-ingone or more sets of features descriptive of characteristics of a segment of audio signal representing a piece of music and deriving a club score that is indicative of at least beat strength associated with said segment of audio signal on basis of said features. According to another example embodiment, the technique comprises obtaining one or more audio attributes characterizing a segment of audio signal representing a piece of music, the audio attributes possibly including the club score, and selecting a switching pattern from a plurality of predetermined switching patterns based at least in part on said one or more audio attributes, wherein a switching pattern is arranged to indicate temporal locations for introduction of discontinuities in visual content associated with said segment of audio signal in relation to temporal locations of beats or downbeats identified for said segment of audio signal.
