Writes Quiros, “Modulation I reflects on modulation as a long-distance information transmission mechanism. Whether digital or analog, modulation builds a rich relational structure between different signals, beyond the physical staff. The signals used in Modulation I come from PSK31 QSO on 20 meters band, radar transmissions on 6 MHz, RTTY activity on 14085 MHz and shortwave broadcast on 19 meters band. Quiros employs digital sound processing to expand the acoustics possibilities of his sources and to construct a sonic reinterpretation of the radio wave spectrum.”
