  • Serra, Xavier (International Computer Music Conference, 1986)
    This paper presents a computer model for bar percussion instruments that captures their main physical characteristics in a very flexible structure. The starting point is current knowledge of the acoustics of the instruments. ...
  • Smith, Julius O.; Serra, Xavier (International Computer Music Conference, 1987)
    This paper describes a peak-tracking spectrum analyzer, called PARSHL, which is useful for extracting additive synthesis parameters from inharmonic sounds such as the piano. PARSHL is based on the Short-Time Fourier Transform ...
  • 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 ...
  • Serra, Xavier; Smith, Julius O. (International Computer Music Conference, 1989)
  • Serra, Xavier; Smith, Julius O. (MIT Press, 1990)
    When generating musical sound on a digital computer, it is important to have a good model whose parameters provide a rich source of meaningf ul sound transformations. Three basic model types are used widely today far musical ...
  • Austin, Larry; Boone, Charles; Serra, Xavier (MIT Press, 1991)
    The three authors each explore an aspect of Larry Austin's 1990 extended composition for radio broadcast. Composer-writer Charles Boone examines the work for its musical and dramatic interest and for its significance as ...
  • Serra, Xavier (Palau de la Música Catalana, 1992)
    Els ordinadors han canviat les nostres vides i sabem que aixo és sols el principi de l'impacte que tindran en un futur no gaire llunyà. Intuïm que seran d'un gran ajut en feines repetitives de tot tipus i que, a la vegada, ...
  • Serra, Xavier (International Computer Music Conference, 1994)
    Phonos Foundation is a center located in the city of Barcelona. It promotes the use of technology in music, combining creation and research. Phonos offers musicians, engineers and scientists a working environment based on ...
  • Serra, Xavier (International Computer Music Conference, 1994)
    Current sound hybridization techniques are ha.sed on the exciter-resonator model, where the spectral characteristics of a sound (resonator) are applied to another one (exciter). The tradi­ tional implementations use Linear ...
  • Serra, Xavier; Bonada, Jordi, 1973-; Herrera Boyer, Perfecto, 1964-; Loureiro, Ramon (International Computer Music Conference, 1997)
    Spectral based analysis/synthesis techniques offer powerful tools for the processing of sounds. They include many different approaches, each one with its own advantages and set of compromises. In the design of a general ...
  • Arcos, Josep Lluís; López de Mántaras, Ramon; Serra, Xavier (International Computer Music Conference, 1997)
    We have studied the problem of generating expressive musical performances in the context of tenor saxophone interpretations. We have done several recordings of a tenor sax playing dierent Jazz ballads with dierent degrees ...
  • 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 ...
  • Amatriain, Xavier; Bonada, Jordi, 1973-; Serra, Xavier (International Conference on Digital Audio Effects, 1998)
    Since the MIDI 1.0 specification, well over 15 years ago, many have been the attempts to give a solution to all the limitations that soon became clear. None of these have had a happy ending, mainly due to commercial ...
  • Serra, Xavier (1998)
    Spectral based analysis/synthesis techniques offer powerful tools for the processing of sounds. They include many different approaches, each one with its own advantages and set of compromises that have to be considered ...
  • Serra, Xavier; Bonada, Jordi, 1973- (International Conference on Digital Audio Effects, 1998)
    The basic Spectral Modeling Synthesis (SMS) technique models sounds as the sum of sinusoids plus a residual. Though this analysis/synthesis system has proved to be successful in transforming sounds, more powerful and ...
  • Arcos, Josep Lluís; López de Mántaras, Ramon; Serra, Xavier (Association for the Advancement of Artificial Intelligence (AAAI), 1998)
    This paper briefly describes a system called SaxEx, capable of generating expressive musical performances based on examples. We have done several recordings of a tenor sax expressively playing Jazz ballads. These recordings ...
  • Wright, Matthew; Chaudhary, Amar; Freed, Adrian; Wessel, David; Rodet, Xavier; Serra, Xavier (International Computer Music Conference, 1998)
    The Sound Description Interchange Format (SDIF) is a recently adopted standard that can store a variety of sound representations including spectral, time domain, and higher-level models. SDIF consists of a specified data ...
  • Resina, Eduard; Serra, Xavier (Associació Musica y Comunicació, 1998)
  • Arcos, Josep Lluís; López de Mántaras, Ramon; Serra, Xavier (Taylor & Francis (Routledge), 1998)
    We have studied the problem of generating expressive musical performances in the context of tenor saxophone interpretations. We have done several recordings of a tenor sax playing different Jazz ballads with different ...
  • Herrera Boyer, Perfecto, 1964-; 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 ...
