  • Srinivasamurthy, Ajay; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    A supervised approach to metrical cycle tracking from audio is presented,/nwith a main focus on tracking the tāḷa, the hierarchical cyclic/nmetrical structure in Carnatic music. Given the tāḷa of a piece, we aim/nto estimate ...
  • Serra, Xavier (1989)
    This dissertation introduces a new analysis/synthesis method. It is designed to obtain musically useful intermediate representations for sound transformations. The method’s underlying model assumes that a sound is composed ...
  • Gulati, Sankalp; Salamon, Justin; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper we propose a new approach for tonic identification in Indian art music and present a proposal for a/ncomplete iterative system for the same. Our method splits the task of tonic pitch identification into two ...
  • Loureiro, Ramon; Serra, Xavier (International Computer Music Conference, 1997)
    The World Wide Web has brought the possibility of distributing multimedia objects through the Internet, becoming a very interesting platform for the development of innovative music and audio applications. Apart from the ...
  • Gouyon, Fabien; Widmer, Gerhard; Serra, Xavier; Flexer, Arthur (University of California Press, 2006)
    This article brings forward the question of which acoustic features are the most adequate for identifying beats computationally in acoustic music pieces. We consider many different features computed on consecutive short ...
  • Fonseca, Eduardo; Gong, Rong; Bogdanov, Dmitry; Slizovskaia, Olga; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (Tampere University of Technology, 2017)
    This work describes our contribution to the acoustic scene classifi- cation task of the DCASE 2017 challenge. We propose a system that consists of the ensemble of two methods of different nature: a feature engineering ...
  • Roma Trepat, Gerard (Universitat Pompeu Fabra, 2015-06-05)
    The rapid adoption of Internet and web technologies has created an opportunity for making music collaboratively by sharing information online. However, current applications for online music making do not take advantage of ...
  • Sentürk, Sertan; Holzapfel, Andre; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    The main information sources to study a particular piece of music are symbolic scores and audio recordings. These are complementary representations of the piece and it is/nvery useful to have a proper linking between the ...
  • Font Corbera, Frederic; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    User generated content shared in online communities is often described using collaborative tagging systems where users assign labels to content resources. As a result, a folksonomy emerges that relates a number of tags ...
  • Font Corbera, Frederic; Serrà Julià, Joan; Serra, Xavier (ACM Association for Computer Machinery, 2015)
    Collaborative tagging systems have emerged as a successful solution for annotating contributed resources to online sharing platforms, facilitating searching, browsing, and organizing their contents. To aid users in the ...
  • Wright, Matthew; Beauchamp, James; Fitz, Kelly; Rodet, Xavier; Röbel, Axel; Serra, Xavier; Wakefield, Gregory (Cambridge University Press, 2000)
    We compared six sound analysis/synthesis systems used for computer music. Each system analysed the same collection of twenty-seven varied input sounds, and output the results in Sound Description Interchange Format (SDIF). ...
  • Srinivasamurthy, Ajay; Holzapfel, Andre; Ganguli, Kaustuv Kanti; Serra, Xavier (Frontiers, 2017)
    This article provides insights into aspects of tempo and rhythmic elaboration in Hindustani music, based on a study of a large corpus of recorded performances. Typical tempo developments and stress patterns within a ...
  • Serrà Julià, Joan; Koduri, Gopala Krishna; Miron, Marius; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    The issue of tuning in Indian classical music has been, historically,/na matter of theoretical debate. In this paper, we/nstudy its contemporary practice in sung performances of Carnatic/nand Hindustani music following an ...
  • Font Corbera, Frederic; Brookes, Tim; Fazekas, George; Guerber, Martin; La Burthe, Amaury; Plans, David; Plumbley, Mark D.; Shaashua, Meir; Wang, Wenwu; Serra, Xavier (Audio Engineering Society, 2016)
    Significant amounts of user-generated audio content, such as sound effects, musical samples and music pieces, are uploaded to online repositories and made available under open licenses. Moreover, a constantly increasing ...
  • Guaus, Enric (Universitat Pompeu Fabra, 2009-09-21)
    Aquesta tesi versa sobre la classificació automàtica de gèneres musicals, basada en l'anàlisi del contingut del senyal d'àudio, plantejant-ne els problemes i proposant solucions. Es proposa un estudi de la ...
  • Herrera Boyer, Perfecto; Serra, Xavier; Peeters, Geoffroy (International Computer Music Conference, 1999)
    Sound content description is one of the aims of the MPEG-7 initiative. Although MPEG-7 focuses on indexing and retrieval of audio, there are other sound content-based processing applications waiting to be developed once ...
  • Marxer Piñón, Ricard (Universitat Pompeu Fabra, 2013-09-09)
    Aquesta tesi proposa mètodes per tractar les limitacions de les tècniques existents de separació de fonts musicals en condicions de baixa i alta latència. En primer lloc, ens centrem en els mètodes amb un baix cost ...
  • Gong, Rong; Pons Puig, Jordi; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2017)
    We approach the singing phrase audio to score matching problem by using phonetic and duration information – with a focus on studying the jingju a cappella singing case. We argue that, due to the existence of a basic ...
  • Dzhambazov, Georgi Bogomilov; Yang, Yile; Caro Repetto, Rafael; Serra, Xavier (International Workshop on Folk Music Analysis, 2016)
    In this study we propose how to modify a standard approach for text-to-speech alignment to apply in the case of alignment of lyrics and singing voice. We model phoneme durations by means of a duration-explicit hidden Markov ...
  • Laurier, Cyril François (Universitat Pompeu Fabra, 2011-09-19)
    In this work, we focus on automatically classifying music by mood. For this purpose, we propose computational models using information extracted from the audio signal. The foundations of such algorithms are based on ...
