    • Sonic Shapes: Visualizing Vocal Expression 

      Pietrowicz, Mary; Karahalios, Karrie (Georgia Institute of TechnologyInternational Community for Auditory Display, 2013-07)
      Sound has been an overlooked modality in visualization. Why? Because it is ephemeral. We experience it as it happens, often in community with others. Then, the sound is gone. Furthermore, sound in human communication ...
