Synthetic Pulsar

By Marcin Pietruszewski & Alex Freiheit

Virtual Binaural Audiovisual Installation for Computer Generated Sounds and Visuals, Human and Synthetic Voices, 2021 »Synthetic Pulsar (Reductive – Additive)« probes the synthetic potential of the pulsar as an integrative object functioning across and within disciplines of astrophysics, technology of sound, and computational speech design. The work’s material point of departure is a new implementation of the pulsar synthesis technique, originally developed by Curtis Roads, in a form of The New Pulsar Generator (nuPG) program designed and programmed by Marcin Pietruszewski. Pulsar synthesis offers a seamless link between musical time-scales of individual particle rhythms, periodic pitches, and the meso temporal or phrase level of composition. Within the work, performer Alex Freiheit’s synthetic voice plays a double role; firstly, as the narrator it thematises processes of synthetic formulation; secondly, as an integral sound generating device its role is to engage with the objectual logics of pulsar and to stage its partial synthesis.
