dots is an interactive sound installation created by nikos moustakas & nikolas grigoriou. The installations’ algorithm takes into account the spatial position of an arbitrary number of participants in order to algorithmically synthesize an audio stream in real-time. The installation core is a software application developed during this work, which employs advanced video and audio processing techniques in order to detect the exact participants’ positions and to weight-mix short audio granules. Audio mixing is performed using a virtual spatial gridding of the installation space in two dimensions. The synthesized audio stream reproduction is combined with a number of appropriately designed visual effects, which aim to enhance the participants’ comprehension and render the “dots” installation a high-quality interactive audiovisual platform.
