Userradio mixes the new technologies of personal communication with "old" broadcast radio technology to create an instrument 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 (for the time) flash-capable browser.
I initially built UserRadio in 2000-2002 for the fundamental radio show where Markus Seidl and I would stream and play sounds directly from our own server that was connected to the radio transmitter on Radio FRO. Since then, I have also used this interface at various festivals and happenings.

UserRadio was a central part in the radio and communication project, "Open Air: a radiotopia". Part of the 2002 Ars Electronica in Linz, UserRadio controled the 4 sets of 100,000 watt speakers of the OMV klangpark. It has also been a part of the Radio Oltranzista and Aaniradio temporary FM stations.
