Applause identification and its relevance to archival of Carnatic music

Abstract

Comunicació presentada al 2nd CompMusic Workshop, celebrat els dies 12 i 13 de juliol de 2012 a Istanbul (Turquia), organitzat per CompMusic.A Carnatic music concert is made up of a sequence of pieces, where each piece corresponds to a particular genre and ra¯aga (melody). Unlike a western music concert, the artist may be applauded intra-performance /ninter-performance. Most Carnatic music that is archived today correspond to a single audio recordings of entire concerts./nThe purpose of this paper is to segment single audio recordings into a sequence of pieces using the/ncharacteristic features of applause and music. Spectral flux, spectral entropy change quite significantly from music to applause and vice-versa. The characteristics of these features for a subset of concerts was studied. A threshold based approach was used to segment the pieces into music fragments and applauses. Preliminary results/non recordings 19 concerts from matched microphones show that the EER is about 17% for a resolution of 0.25 seconds. Further, a parameter called CUSUM is estimated/nfor the applause regions. The CUSUM values determine the strength of the applause. The CUSUM is used to characterise the highlights of a concert.This research was partly funded by the European Research Council under the European Unions Seventh Framework Program, as part of the CompMusic project (ERC grant/nagreement 267583)
