Went out to Adlershof with Jens today to visit gfai, the “Gesellschaft zur Förderung angewandter Informatik e.V.”, where the acoustic camera is being developed, and generously provided for the duration of this project.
In the background you can see the circular microphone array that feeds the analysis system. On the table there’s my ultrasound generator connected to the back of a cardboard speaker box.
Red Psi Donkey is a project inspired by imagery of the so-called “acoustic camera”, which is typically used in industry to locate and measure sound sources in a given scene.
In our case this sonic scene will be meticulously composed in a way such that an image of a donkey appears on the analysis screen. To add further confusion we plan on using ultrasound speakers, so nothing can be heard in the installation.
