In the online world, many of the social cues that are fundamental to coherent communication and the establishment of a vibrant community are missing. The goal of social visualization research is to make legible the patterns and interactions that occur in online social environments. This project extends that research into the audio domain. We are developing techniques for audibly depicting online crowds. Key to this work is both the development of a 3-D audio environment and the creation of a cognitively grounded and aesthetically interesting sound representation.
