  • 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 ...
  • Nogueira, Waldo; Gajecki, Tom; Krüger, Benjamin; Janer Mestres, Jordi; Büchner, Andreas (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    The aim of this study is to investigate whether a source separation algorithm based on a deep recurrent neural network (DRNN) can provide a speech perception benefit for cochlear implant users when speech signals are mixed ...
  • Roma Trepat, Gerard; Janer Mestres, Jordi; Kersten, Stefan; Schirosa, Mattia; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Hindawi, 2010)
    In this paper we present a method to search for environmental sounds in large unstructured databases of user-submitted audio, using a general sound events taxonomy from ecological acoustics. We discuss the use of Support ...
  • Miron, Marius; Janer Mestres, Jordi; Gómez Gutiérrez, Emilia, 1975- (Aalto University, 2017)
    Deep learning approaches have become increasingly popular in estimating time-frequency masks for audio source separation. However, training neural networks usually requires a considerable amount of data. Music data is ...
  • Janer Mestres, Jordi; Gómez Gutiérrez, Emilia, 1975-; Martorell Domínguez, Agustín; Miron, Marius; de Wit, Benjamin (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper combines Audio Signal Processing and Virtual Reality (VR) content to create novel immersive experiences for orchestral music audiences. In VR, the auralization of sound sources of recorded live content remains ...
  • Miron, Marius; Janer Mestres, Jordi; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2017)
    Score information has been shown to improve music source separation when included into non-negative matrix factorization (NMF) frameworks. Recently, deep learning approaches have outperformed NMF methods in terms ...
  • Chandna, Pritish; Miron, Marius; Janer Mestres, Jordi; Gómez Gutiérrez, Emilia, 1975- (Springer, 2017)
    In this paper we introduce a low-latency monaural source separation framework using a Convolutional Neural Network (CNN). We use a CNN to estimate time-frequency soft masks which are applied for source separation. We ...
  • Pons, Jordi; Janer Mestres, Jordi; Rode, Thilo; Nogueira, Waldo (Acoustical Society of America, 2016)
    Music perception remains rather poor for many Cochlear Implant (CI) users due to the users' deficient pitch perception. However, comprehensible vocals and simple music structures are well perceived by many CI users. In ...
  • Miron, Marius; Carabias Orti, Julio J.; Bosch, Juan J.; Gómez Gutiérrez, Emilia, 1975-; Janer Mestres, Jordi (Hindawi, 2016)
    This paper proposes a system for score-informed audio source separation for multichannel orchestral recordings. The orchestral music repertoire relies on the existence of scores. Thus, a reliable separation requires a good ...
  • Janer Mestres, Jordi (Universitat Pompeu Fabra, 2008-03-14)
    Els instruments musicals digitals es descomponen usualment en dues parts: la interfície d'usuari i el motor de síntesi. Tradicionalment la interfície d'usuari pren el nom de controlador musical. L'objectiu d'aquesta tesi ...
  • Janer Mestres, Jordi; Haro Berois, Martín; Roma Trepat, Gerard; Fujishima, Takuya; Kojima, Naoaki ([Sound and Music Computing], 2009)
    Sample-based music composition often involves the task of manually searching appropriate samples from existing audio. Audio mosaicing can be regarded as a way to automatize this process by specifying the desired audio ...
  • Janer Mestres, Jordi; Finney, Nathaniel; Roma Trepat, Gerard; Kersten, Stefan; Serra, Xavier (University of Texas at Austin. Department of Radio-Television-Film, 2009)
    The computer-assisted design of soundscapes for virtual environments has received far less attention than the creation of graphical content. In this “think piece” we briefly introduce the principal characteristics of a ...
