Soundflag, a project by Felix Egle and Dennis Nedbal
21 piezo microphones are connected between a 21g/m2 fabric. The Microphones are collected in a stereo signal. The wind produces microcurrents when bending the piezo plates in the flag tissue. The currents are amplified to an audible level so the shape of the air around the flag is transferred to the perception of the recipient, creating dynamic acoustic shapes following the airflows. Transferring the immaterial movements of airs interaction with bendable tissue to an acoustic spatial impression.
Connected to a MIDI device the flag can be used as trigger for preselected samples. Triggering a Markov Chain Algorithm Rhetoric software the flag has even the potential to talk sentences and create meaning of movements.
