Unsupervised Generation of Percussion Sound Sequences from a Sound Example

Title Unsupervised Generation of Percussion Sound Sequences from a Sound Example
Publication Type Conference Paper

Abstract In this paper we present a system that learns rhythmic patterns from drum audio recording and synthesizes music variations from the learnt sequence. The procedure described is completely unsupervised and embodies the transcription of a percussion sequence into a fuzzy multilevel representation. Moreover, a tempo estimation procedure identifying the most regular subsequence is used to guarantee that the metrical structure is preserved in the generated sequence. The final synthesis is performed, recombining the audio material derived from the sample itself. Some examples of generations along with a descriptive evaluation are provided.
