  • Roma Trepat, Gerard; Serra, Xavier (Web Audio Conference, 2015)
    On the web, searching for sounds is usually limited to text queries. This requires adding textual descriptions to each audio file, which is indexed effectively as a text document. Recent developments in browser technologies ...
  • Roma Trepat, Gerard; Serra, Xavier (Web Audio Conference, 2015)
    Technologies for discovering sounds in large databases can help breaking the boundary between exploration and music performance. In this paper, we present a system for exploring loops from Freesound. Sound files are grouped ...
  • Font, Frederic; Oramas, Sergio; Fazekas, György; Serra, Xavier (CEUR Workshop Proceedings, 2014)
    Currently proposed tagging ontologies are mostly focused on the definition of a common schema for representing the agents involved in a tagging process. In this paper we describe preliminary research around the idea of ...
  • Do, Heedong; Lee, Namyoon; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    We establish an upper bound on the informationtheoretic capacity of line-of-sight (LOS) multiantenna channels with arbitrary antenna arrangements and identify array structures that, properly configured, can attain at least ...
  • Serra, Xavier (Springer, 2002)
  • Colomer, Marc; Sebastián-Gallés, Núria (Elsevier, 2020)
    Infants expect native and non-native speech to communicate, i.e. to transfer information between third-parties. Here, we explored if infants understand that communication depends on the use of shared conventional systems ...
  • Celma Miralles, Alexandre, 1991-; Toro Soto, Juan Manuel, 1976- (Springer, 2020)
    The musical motives of a song emerge from the temporal arrangement of discrete tones. These tones normally have few durational values, and are organized in structured groups to create metrical patterns. In the present study ...
  • Albó, Laia; Beardsley, Marc; Martínez Moreno, Judit; Santos Rodríguez, Patrícia; Hernández Leo, Davinia (Springer, 2020)
    COVID-19 thrust teachers into emergency online pedagogy. Teachers had to rapidly digitize their practices. A week into compulsory online teaching, we captured a snapshot of teacher experiences to identify their impressions ...
  • Papiotis, Panagiotis, 1985-; Herrera Boyer, Perfecto, 1964-; Marchini, Marco, 1984-; Maestre Gómez, Esteban (University of Jyväskylä, 2013)
    In a musical ensemble musicians can influence each other’s performance in terms not only of timing but also in other aspects of the performance such as dynamics, intonation, and timbre. The goal of this work is to test ...

    Over the last decade, audio analysis has become afield of active research in academic and engineeringworlds. It refers to the extraction of information andmeaning from audio signals for analysis, ...
  • Ostuni, Vito Claudio; Di Noia, Tommaso; Di Sciascio, Eugenio; Oramas, Sergio; Serra, Xavier (ACM Association for Computer Machinery, 2015)
    In this work we describe a hybrid recommendation approach for recommending sounds to users by exploiting and semantically enriching textual information such as tags and sounds descriptions. As a case study we used Freesound, ...
  • Font Corbera, Frederic; Roma Trepat, Gerard; Serra, Xavier (ACM Association for Computer Machinery, 2013)
    Freesound is an online collaborative sound database where people with diverse interests share recorded sound samples under Creative Commons licenses. It was started in 2005 and it is being maintained to support diverse ...
  • Chatillon, Pierrick; Ballester, Coloma (Springer, 2020)
    Anomaly detection is a difficult problem in many areas and has recently been subject to a lot of attention. Classifying unseen data as anomalous is a challenging matter. Latest proposed methods rely on Generative Adversarial ...
  • Raad, Lara; Oliver Parera, Maria; Ballester, Coloma; Haro Ortega, Gloria; Meinhardt Llopis, Enric (IPOL, 2020)
    This work describes two anisotropic optical flow inpainting algorithms. The first one recovers the missing flow values using the Absolutely Minimizing Lipschitz Extension partial differential equation (also called infinity ...
  • Roma Trepat, Gerard; Herrera Boyer, Perfecto, 1964-; Nogueira, Waldo (Springer, 2018)
    Recognition of environmental sound is usually based on two main architectures, depending on whether the model is trained with frame-level features or with aggregated descriptions of acoustic scenes or events. The former ...
  • Beardsley, Marc; Martínez Moreno, Judit; Santos Rodríguez, Patrícia; Hernández Leo, Davinia (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Whether deciding to participate in a study or gain access to online applications, research suggests that individuals often fail to understand the conditions they agree to when giving consent. Limited comprehension related ...
  • Beardsley, Marc; Gutierrez, Nicolas; Hernández Leo, Davinia (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Learning to learn has been identified as an underdeveloped yet critical skill for learners. However, interventions often struggle to alter learner behavior in a lasting manner. We conducted a quasi-experimental study, ...
  • Beardsley, Marc; Vujovic, Milica; Theophilou, Emily; Hernández Leo, Davinia; Portero Tresserra, Marta (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Self-reports of affective states are increasingly being collected in educational settings. However, individual definitions and usage of emotion and mood terms are often subjective despite objective definitions becoming ...
  • Albó, Laia; Beardsley, Marc; Amarasinghe, Ishari; Hernández Leo, Davinia (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Researchers have demonstrated the effectiveness of self-explanations (SE) as an instructional practice and study strategy. However, there is a lack of work studying the characteristics of SE responses prompted by collaborative ...
  • Accuosto, Pablo; Saggion, Horacio (Elsevier, 2020)
    Argument mining consists in the automatic identification of argumentative structures in texts. In this work we leverage existing discourse-level annotations to facilitate the identification of argumentative components and ...
