"The teletype as a form of audio transmission of a message inspired me to think about hidden messages and data corruption. Using audio heterodyning, I recoded a message and modulated this about 18KHz. This is throughout the piece, but you cannot hear it. Using a de-modulator I can bring this down to the audible range, this can be heard in the piece. The slow pulses are the messages transferred by the teletype the indented message, finally corrupted in the end."
