LITERAL:
Userradio mixes the new technologies of personal communication with «old» broadcast radio technology. It is a set of tools for collaborative networked audio production, where an unlimited number of individuals can mix multiple channels of audio simultaneously and together from anywhere on-line using a standard flash-capable browser. The audio output of the application is broadcast on terrestrial FM radio and the users are ideally within the broadcast diameter.
