A location-based audio experience that triggers soundfiles as you move through the city of Helsinki. There are two types of triggers: smaller round ones (pins) and larger polygonal ones (zones). Pins contain shorter looping sounds, while zones are the areas where longer narrative files are played. Pins get louder depending how close or far one is, while areas have the same internal volume, but fade away when one exits.
The sound can be paused and resumed at will and areas can also be skipped and restarted if skipped or finished. The experience can be visited at one's own pace and it is possible to visit different areas in different days. You can just listen for as long as you like!
There can also be the option to visit the app from home by simulating the position via a mouse click (not available yet).
