    • 3D audio as an information-environment: Manipulating perceptual significance for differentiation and pre-selection 

      Lennox, Peter P; Vaughan, John M; Myatt, Tony (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      Contemporary use of sound as artificial information display is rudimentary, with little 'depth of significance' to facilitate users' selective attention. We believe that this is due to conceptual neglect of 'context' or ...
    • 3D audio interfaces for the blind 

      Frauenberger, Christopher; Noistering, Markus (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Our work is dealing with alternative interaction modes for visually impaired and blind people to use computers. The aim of the proposed approach is to exploit the human hearing capabilities to a better degree than this is ...

      A method of computationally efficient 3D sound reproduction via headphones is presented using a virtual Ambisonic approach. Previous studies have shown that incorporating head tracking as well as room simulation is important ...
    • Acoustic cues for 3-D shape information 

      Rocchesso, Davide (Georgia Institute of TechnologyInternational Community on Auditory Display, 2001-07)
      Three-dimensional resonators, such as cavities or rooms, affect the perceived timbral character of any sound source there enclosed. It is well understood how the resonator size, or the material of the enclosure, are conveyed ...
    • Case study of a software structure for a 3D-Audio-Device 

      Lehmann, Thomas (Georgia Institute of TechnologyInternational Community on Auditory Display, 1998-11)
      The simulation of an auditory environment is audio signal processing depending on an acoustical model method and a given scene model. For signal processing we use a set of signal processing objects which can be glued to a ...
    • COOLVR: Implementing Audio in a Virtual Environment Toolkit 

      Pair, Jarrell; Kooper, Rob (Georgia Institute of Technology, 1998)
      COOLVR (Complete Object Oriented Library for Virtual Reality) is a toolkit currently being developed at the Graphics, Visualization, and Usability Center (GVU) at Georgia Tech. The toolkit is written to allow programmers ...
    • Extending SMIL with 3D audio 

      Pihkala, Kari; Lokki, Tapio (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      This paper describes how SMIL can be extended to support 3D audio in a similar fashion than AABIFS does it for MPEG-4. The SMIL 2D layout is extended with an extra dimension to support a 3D space. New audio elements are ...
    • An independent declarative 3D audio format on the basis of XML 

      Hoffmann, Heiko; Dachselt, Raimund; Meissner, Klaus (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      This paper describes the development of an XML-based format called Audio3D for the declarative description of acoustic environments and sound sources for 3D auditory displays by an audio designer without the need of ...
    • The NAVE: Design and implementation of a 3D audio system for a low cost spatially immersive display 

      Wilson, Jeff; Pair, Jarrell (Georgia Institute of TechnologyInternational Community for Auditory Display, 2000-04)
      The NAVE is a low cost spatially immersive display system developed by the Georgia Tech Virtual Environments Group. The NAVE audio environment uses two independent speaker systems driven by a dedicated audio PC with two ...
    • Occurrence of simulator sickness in spatial sound spaces and 3d auditory displays 

      Dicke, Christina; Aaltonen, Viljakaisa; Billinghurst, Mark (Georgia Institute of TechnologyInternational Community for Auditory Display, 2009-05)
      This paper describes an investigation into the effect of movement patterns in a spatial sound space on the perceived amount of simulator sickness, the pleasantness of the experience, and the perceived workload. Our user ...
    • Real-time, head-tracked 3D audio with unlimited simultaneous sounds 

      Jin, Craig; Tan, Teewon; Kan, Alan; Lin, Dennis; Schaik, Andre van; Smith, Keir; McGinity, Matthew (Georgia Institute of TechnologyInternational Community on Auditory Display, 2005-07)
      This research presents a novel 3D audio playback method in which real-time head-tracking is maintained with an unlimited number of simultaneous sound sources. The method presented relies on using a 500-900MByte sound buffer ...
