Microradio Sound Walk is a experimental media art event and walking tour of a location’s airwaves utilizing transmission tools to create a soundscape that responds to both the architecture and sonic phenomena of the space surrounding Hallwalls.

Microradio Sound Walk consists of three transmission stations: –“Local Frequencies,” “Environmental Nature,” and “Social Spaces” –situated along a loosely defined route. Three artists are placed roughly equidistant from one and other. Each microcasts their signal on the same FM frequency. As visitors take the Microradio Sound Walk the three signals fade in and out depending on the listeners’ movement and proximity to each artist. Participants who encounter radios or are lent radios with headphones proceed through the route in the order of their choosing, as they move farther away from one station and grow closer to the next, the signal they receive too shifts. This sonic progression maps the spatial qualities of the airwaves and provides a tangible example of their ubiquitousness.
