  • 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; Smith, Julius O. (International Computer Music Conference, 1989)
  • 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 (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; Bonada, Jordi, 1973-; Herrera Boyer, Perfecto; 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 (International Computer Music Conference, 1999)
    The Musicians' Software Mall is a software package developed to provide powerful composition and performance tools to the computer musician. At this stage it contains the following applications: SmsTools 2.0, a set of tools ...
  • 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 ...
  • Cano, 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 ...
  • de Boer, Marteen; Bonada, Jordi, 1973-; Cano, 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 ...
  • de Boer, Marteen; Bonada, Jordi, 1973-; Serra, Xavier (International Computer Music Conference, 2000)
    Recently, we have seen an increased use and support of the Sound Description Interchange Format (SDIF), among which the integration of SDIF in widely used environments such as MAX/MSP (Wright, Dudas, Khoury, Wang, Zicarelli, ...
  • Serra, Xavier (International Computer Music Conference, 2000)
    The Audiovisual Institute (http://www.iua.upf.es) is a research center of the Pompeu Fabra University, (http://www.upf.es) located in Barcelona and devoted to new media technologies. Apart from its main research activities, ...
  • Herrera Boyer, Perfecto; Amatriain, Xavier; Batlle, Eloi; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2000)
    A system capable of describing the musical content of any kind of sound file or sound stream, as it is supposed to be done in MPEG7-compliant applications, should provide an account of the different moments where a certain ...
