One often overlooked beauty of analogue radio is the possibility of tuning through a waveband without finding a station but to encounter the most interesting noise patterns. Any form of digital broadcasting will forsake this opportunity. Ersatzrauschen is an imagined tuning through an empty waveband on the dial, offering the rather unlikely chance for the listener to stumble across it whilst hopping through discrete internet streams. The sound source for the piece is not radio but a malfunctioning 8-track digital data tape recorder made by Bell & Howell. A built in self-test function produced variable noise patterns on the eight individual outputs which I used to perform a real-time mix.
