A hovering object that explores and manipulates transitional public spaces with particular acoustic properties. By constantly recording and replaying these ambient sounds, the levitating sphere produces a delayed echo of human activity.
In this project, the Arduino board and an Adafruit Wave Shield is used. The Wave shield is not designed to record audio however, they say that they use the board for both recording and playback.
The sphere responds sonically to people and its surroundings by means of a battery-powered Arduino, an Adafruit Wave Shield hacked to record and playback audio on-the-fly and a small speaker.
This generates a few questions.
- How would this be done?
- Where would the microphone be placed inside the balloon for decent audio capture?
- Would there be a better way to design this?
