In thispaperwedescribeamethodfor thetranscriptionof percussive audiosignalswhich have beenperformedwith arbitrarynondrumsounds.Thesystemlocatessoundeventsfrom theinputsignal using an onsetdetector . Then a set of featuresis extracted from the onsettimes.Featurevectorsareclusteredandthe clustersareassignedwith labelswhich describethe rhythmic role of eachevent.For thelabeling,a novel methodis proposedwhich is basedon metrical(temporal)positionsof thesoundeventswithin themeasures. Thesystemis evaluatedusingmonophonicpercussive tracks consistingof non-drumsounds.In simulations,the systemachieved a total error rate of 33.7%.
