Etherscape

Etherscape is a behavioral system that interacts with wireless networks into a perceptible and sensory encounter by converting data into audio signals. This allows the user to encounter the intangible networks in urban surroundings and adds an additional layer to the current physical environment. Using this device, users can explore urban spaces by sensing the strength and variability of wireless signals. In order to scan network points in real-time, a Python script is executed when the Raspberry Pi is turned on. The script can detect the SSID and signal strength of up to 10 network points, and the data is fed to a pure data patch via the OSC communication protocol. The sonic language used in this project comes from four different sound sources: a simple synth, resonators, a sampler and a microphone.

The device invites me to explore different spaces as the sonic language evolves from one location to location. As I stay in one place to observe the produced sound, I assign meaning to such a place as the generated soundscape gives me a new impression. Sudden changes in the sound produced by the device trigger me to observe their environment and to be aware of the space I am currently located in. For example, my apartment or my nearest grocery store always generated similar tonal qualities that I can recognize. The produced sound also encourages me to either go to a busier urban space where it is rich in network, or to a quieter space where there is less. However, in quieter spaces, a disturbance in the sound produced is very apparent, prompting me to look at their surroundings for the source of the disturbance. Another interesting experience with the device happened when it is used in a fast moving vehicle such as a train. Obvious contrasts and rapid changes can be heard while moving through cities and rural areas. I’ve only fully used the device for a short period of time, and I would really like to explore further the tonal impressions of other spaces. This work is part of Sound, Space & Interaction course in the Media Technology programme.
