      Wenzel, Elizabeth M (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      In a virtual acoustic environment, the total system latency (TSL) refers to the time elapsed from the transduction of an event or action, such as movement of the head, until the consequences of that action cause the ...

      Bresin, Roberto; Friberg, Anders (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      Recent research on the analysis and synthesis of music performance has resulted in tools for the control of the expressive content in automatic music performance [1]. These results can be relevant for applications other ...
    • Feasibility of multiple non-speech sounds presentation using headphones 

      Lorho, Gaetan; Marila, Juha; Hipakka, Jarmo (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      This paper describes a study of listeners' ability to segregate spatially separated sources of non-speech sounds. Short sounds from musical instruments were played over headphones at different spatial positions using stereo ...
    • Graphics and user's exploration via simple sonics (GUESS): Providing interrelational representation of objects in a non-visual environment 

      Kamel, Hesham M; Roth, Patrick; Sinha, Rashmi (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      In this research we investigated the use of the GUESS system in the exploration of auditory pattern perception by blind and visually impaired people. We have compared three different techniques for presenting graphical ...
    • Here, there and everywhere: The effects of multichannel audio on presence 

      Freeman, J; Lessiter, J (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      In this paper `presence' (a sense of `being there' in a mediated environment) is proposed as a global metric with which to evaluate audio displays that are part of advanced multi-modal media systems. An evaluation of ...
    • The importance of head movements for binaural room synthesis 

      Minnaar, Pauli; Olesen, Soren Krarup; Christensen, Flemming; Moller, Henrik (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      The contribution of head movements to sound localisation of loudspeakers in a listening room was investigated. An experiment was done where listeners either were requested to keep their heads still while sound was being ...
    • JASS: A java audio synthesis system for programmers 

      van den Doel, Kees; Pai, Dinesh K (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      We describe a unit generator based audio synthesis programming environment written in pure Java. The environment is based on a foundation structure consisting of a small number of Java interfaces and abstract classes, and ...
