The user with a special vest (while walking on the streets) navigates through different sound data fields. These virtual spaces differ from the geographic city scape. altering the position, the visitor controls the timeline of spatial organized sounds.
Different sound spaces which are defined by radio connections, ovarlay with each other and with the real physical space. The rigid boundaries of the architecture does not allow users to listen to certain regions of the work, they remain "untouched".
Mapamp uses existing stuctures and systems (architecture of a city, navigation and radio systems) in order to layer an artificial acousitc space over original auditive space. The resuling diffusion of these layers makes possible to experience frontiers of data spaces and public space .
