  • Content processing of music audio signals
    Gouyon, Fabien; Herrera Boyer, Perfecto, 1964-; Gómez Gutiérrez, Emilia, 1975-; Cano Vila, Pedro; Bonada, Jordi, 1973-; Loscos, Àlex; Amatriain, Xavier; Serra, Xavier (Logos Verlag, 2008)
    In this chapter, we provide an overview of state-of-the-art algorithms for the automatic description of music audio signals, both from a low-level perspective (focusing on signal characteristics) and a more musical perspective ...
  • Content-based transformations
    Amatriain, Xavier; Bonada, Jordi, 1973-; Loscos, Àlex; Arcos, Josep Lluís; Verfaille, Vincent (Taylor & Francis, 2003)
    Content processing is a vast and growing field that integratesdifferent approaches borrowed from the signal processing,information retrieval and machine learning disciplines. Inthis article we deal with a ...
  • Singing voice impersonator application for PC
    de Boer, Marteen; Bonada, Jordi, 1973-; Cano Vila, Pedro; Loscos, Àlex; Serra, Xavier (International Computer Music Conference, 2000)
    This paper presents the implementation aspects of a real-time system for morphing two voices in the context of a karaoke application. It describes the software design and implementation under a PC platform and it discusses ...
  • Singing voice synthesis combining excitation plus resonance and sinusoidal plus residual models
    Bonada, Jordi, 1973-; Celma Herrada, Òscar; Loscos, Àlex; Ortolà, Jaume; Serra, Xavier; Yoshioka, Yasuo; Kayama, Hiraku; Hisaminato, Yuji; Kenmochi, Hideki (International Computer Music Conference, 2001)
    This paper presents an approach to the modeling of the singing voice with a particular emphasis on the naturalness of the resulting synthetic voice. The underlying analysis/synthesis technique is based on the Spectral ...
  • Spectral approach to the modeling of the singing voice
    Bonada, Jordi, 1973-; Loscos, Àlex; Cano Vila, Pedro; Serra, Xavier; Kenmochi, Hideki (Audio Engineering Society, 2001)
    In this paper we present two different approaches to the modeling of the singing voice. Each of these approaches has been thought to fit in the specific requirements of two applications. These are an automatic voice impersonator ...
  • Spectral modeling for higher-level sound transformation
    Amatriain, Xavier; Bonada, Jordi, 1973-; Loscos, Àlex; Serra, Xavier (2001)
    When designing audio effects for music processing, we are always aiming at providing higherlevel representations that may somehow fill in the gap between the signal processing world and the end-user. Spectral models in ...
  • Spectral Processing
    Amatriain, Xavier; Bonada, Jordi, 1973-; Loscos, Àlex; Serra, Xavier (John Wiley & Sons, 2002)
    In the context of this book, we are looking for representations of sound signals and signal processing systems that can give us ways to design sound transformations in a variety of music applications and contexts. It should ...
  • Spectral processing of the singing voice
    Loscos, Àlex (Universitat Pompeu Fabra, 2011-04-12)
    Aquesta tesi doctoral versa sobre el processament digital de la veu cantada, més concretament, sobre l'anàlisi, transformació i síntesi d'aquets tipus de veu en el domini espectral, amb especial èmfasi en aquelles tècniques ...
  • Voice morphing system for impersonating in karaoke applications
    Cano Vila, Pedro; Loscos, Àlex; Bonada, Jordi, 1973-; de Boer, Marteen; Serra, Xavier (International Computer Music Conference, 2000)
    In this paper we present a real-time system for morphing two voices in the context of a karaoke application. As the user sings a pre-established song, his pitch, timbre, vibrato and articulation can be modified to resemble ...
