Algorithmic Cross-Mixing And Rhythmic Derangement

This paper discusses the circumstances and the results in automating rhythmical derangement of popular music in order to render an odd-meter version of a tune. The resulting pieces will be performed in a late night concert of the International Computer Music Conference resembling a typical DJ performance setting. Created remixes often use two widely known tunes in parallel to bear the title of a cross-mix. The cross-mixes are made by firstly synchronising the tracks in their original timeflow by using audio stretching techniques. Secondly, the probabilistic splicing algorithms and further timestretching are employed to render the tracks within a different metric structure. Finally, DJ production and performance techniques provide appropriate ways of mastering and presenting the pieces in a club-type environment. The paper will further deal with the intentions behind using popular tunes, odd-meters and algorithms in the light of the motivation that yielded the currently presented system. The designed software plug-in will be briefly documented and made public as open-source development.
