    • LSL: A specification language for program auralization 

      Mathur, Aditya P.; Boardman, David B.; Khandelwal, Vivek (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The need for specification of sound patterns to be played during program execution arises in contexts where program auralization is useful. We present a language named LSL (Listen Speciikation Language) designed for ...
    • An organization for high-level interactive control of sound 

      Das, Sumit; DeFanti, Tom; Sandin, Dan (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The state of computer generated sound has advanced rapidly, and there exist many different ways of conceptualizing the abstract sound structures that comprise music and other complex organizations of sound. Many of these ...

      Albers, Michael C (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
    • Designing with auditory icons 

      Mynatt, Elizabeth D. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Current research in auditory interfaces has produced a number of interesting interfaces without resulting in the compilation of design guidelines for creating descendent interfaces. This lack of a common design methodology ...
    • Efficient modeling of the head-related transfer functions 

      Lueck, Charles (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Efficient representations of the head-related transfer functions (HRTFs) based on autoregressive moving average (ARMA) modeling are explored in this chapter. A relatively new technique for ARMA order estimation, based on ...
    • Perception of virtual auditory shapes 

      Hollander, Ari J.; Furness III, Thomas A. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Virtual environments may help us to understand and eventually extend the domain of auditory perception. The authors performed two experiments which verified the ability of subjects to recognize geometric shapes and ...
    • Using virtual environment technology to present a digital sound library 

      Whitehead, John F (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Digital sound libraries of today can be difficult to navigate. For example, sampling keyboards often display only the currently selected sound, and it is not easy to know the adjacent sounds or how to find desired ones. ...
    • On the role of head-related transfer function spectral notches in the judgement of sound source elevation 

      Macpherson, Ewan A. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Using a simple model of sound source elevation judgment, an attempt was made to predict two aspects of listeners' localization behavior from measurements of the positions of the primary high-frequency notch in their ...
    • Task-oriented quantitative testing for synthesized 3-D auditory displays 

      Julig, Louise Frantzen; Kaiwi, Jerry L. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Current human machine interfaces in Navy systems which incorporate headphone listening fail to take full advantage of human binaural sensory processing capabilities. These interfaces can be improved by providing the ...
    • Sound localization in varying virtual acoustic environments 

      Zahorik, Pavel; Kistler, Doris J; Wightman, Frederic L (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      {Localization performance was examined in three types of headphone-presented virtual acoustic environments: an anechoic virtual environment, an echoic virtual environment, and an echoic virtual environment for which the ...
    • GUI admission for VIPs: A sound initiative 

      Poll, L.H.D; Eggen, J.H. (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Until now, mostly character-based applications were used on office computers. These applications could be accessed by visually impaired persons(VIPs) using Braille or synthetic speech. Recently, there has been a shift ...
    • The run-time components of sonnett 

      Jameson, David H (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Sonnet is an audio-enhanced monitoring and debugging system whose aim is to investigate how sound can be used in a program development environment. Running under AIX, it consists of a visual programming language to design ...
    • A centralized audio presentation system 

      Papp III, Albert L; Blattner, Meera M (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The centralized audio presentation system addresses the problems which occur when multiple programs running simultaneously attempt to use the audio output of a computer system. Concurrent audio output can lead to perceptual ...
    • Factors in the design of effective auditory displays 

      Watson, Charles S; Kidd, Gary R (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      The design of effective auditory displays requires an understanding of both capabilities and response proclivities. This disti ctionis explained in relation to a variety of auditory tasks and a range of acoustic stimuli. ...
    • An evaluation of the communicative ability of auditory icons and earcons 

      Lucas, Paul A (Georgia Institute of TechnologyInternational Community on Auditory Display, 1994-11)
      Audio cues are increasingly used to present information in the human-computer interface. To be of use, these cues must effectively communicate the intended information to the user. An evaluation of two types of nonspeech ...
