Selbsportrait mit Peter Ablinger is either an installation or a work that runs as the audience enters a concert. In its setup, the computer listens to and spectrally freezes the sound in the room every six seconds. At the same time it analyzes the frozen spectra that it captures and notates the strongest formants on a large screen that hangs at the front of the space. An ensemble placed around the space reads from the score on the screen and plays the notated pitches. There is an endless feedback between performers and space, resulting in a constantly changing wall of sound. The performance below is by the Wet Ink Ensemble at St Peters Church in Chelsea, NYC.
