Audiovisual Installation: Interactive imprinting of sound in water

The present project is an interactive audiovisual creation, a sound and vision installation where the user interactively activates sound in its analog form. The sound is used to influence a physical medium (in this case a tank full of water) producing an image through the turbulences on its surface. This image, properly illuminated, is reflected and visualised in space. The installation is designed in such a way that allows, through an interactive application, the projection of sound on the water surface and the direct capture of that feedback, i.e. sound waves formed on water. At the same time, the reflected image is projected on a white surface (“imprint of sound” – projection of sound as image). The innovation of the project consists in the interactional mechanism of the system developed, which allowes the users to influence the final visual effect while they are moving in the room of the installation. Moreover, the interactive methodology chosen, allowed the system to work succesfully with the use of low-budget sensors, without that being a burden to the operability of the system. The programmes used for the interactive mechanism are open source softwares. For the detection of blobs from the camera has been used Processing, and for the sound SuperCollider.
