    • Focalisation on the temporal context of complex sequences 

      Guillaume, Anne; Drake, Carolyn (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Studies of the perception of sound sequences indicate the existence of an optimal processing rate [1]: sequences in which sound events occur at rates within this range are processed in more depth than events within faster ...

      In this paper, we discuss the design and implementation of D'Groove, an intelligent Disc Jockey (DJ) system that uses a haptic turntable for controlling the playback of digital audio. We begin by describing the tasks of a ...
    • Household appliances control device for the elderly 

      England, David; Salces, Fausto J Sainz; Vickers, Paul (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      An evaluation of musical earcons was carried out to see whether they are an effective and efficient method of delivering information about household appliances to elderly people. A test was carried out to explore the ability ...
    • Identifying where you are in a room: Sensitivity to room acoustics 

      Shinn-Cunningham, Barbara; Ram, Suraj (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      In a spatial auditory display, reverberation provides a reliable cue for source distance, increases the subjective realism of the display, and improves the externalization of simulated sound sources. However, relatively ...
    • The IEM-cube 

      Zmolnig, Johannes; Ritsch, Winfried; Sontacchi, Alois (Georgia Institute of TechnologyInternational Community on Auditory Display, 2003-07)
      Traditional multichannel-reproduction systems are mainly used for recreation of pantophonic sound elds. Fully periphonic reproduction has been limited by computational power to manipulate large numbers of audio-channels ...
