di.uoa.gr"Locating Rhythmic
Patterns in Music Examples Using Hidden Markov Models", ICAASP 2007, April 15 - 20, 2007, Honolulu, Hawaii, USA.
Iasonas Antonopoulos, Aggelos Pikrakis and Segios Theodoridis
Audio examples :
In the following table the overall results of locating rhyhtmic patterns using the HMM are presented followed by some audio examples sorted per musical meter.
The audio examples are selected randomly from the music corpus of our experimentsto demonstrate how the algorithm works.
In those audio examples, a "boot" sound has been placed at the beggining of a rhythmic pattern and a "clap" sound at every other rhythmic pattern state.
