Velocidade terminal: Tempo chronoscopico dos corpor obritais na composição sonora e musical.

This essay presents the methodologies, meanings and challenges in the development of the “Dromology of Orbital Bodies”, Hugo Paquete project, started between 2019-2020 and still ongoing. The project aims to track military and commercial satellites, by converting their movement information in real time by a process of data sonification received from the hacked satellites. Therefore, this essay presents the technical challenges in the project building, as well some of the obtained sonic results. Also is presented the dimension of conceptual meanings associated with the project from a philosophical and critical point of view, in a combination of conceptual approach and technical exploration where concepts such as chronoscopic time, cyberpunk, gray ecology and acoustemology are related as conceptual frames, of a time where the sound happens mediated by technology. The presented concepts are influences in the production, composition and musical performance processes that I develop with special interest in systems theory and where unpredictability operates alongside real-time relationships. In this experimentation I use sound granularization and compositional aesthetic techniques historically centered in a noise and micro post-digital rhythm aesthetics.

Inner Rhythms: Vessels as a sustained brain-body performance practice

Vessels is a brain-body performance practice that combines flute improvisation with live, sonified brain and body data. This article describes the genesis of this performance practice, which co-evolved with her new brain-music interfacing and physiological data sonification methods. The author presents these novel interface designs and discusses how the affordances and constraints of these systems reflect onto her brain-body performance technique.

Intentionality and design in the data sonification of social issues

Data sonification is a practice for conducting scientific analysis through the use of sound to represent data. It is now transitioning to a practice for communicating and reaching wider publics by expanding the range of languages and senses for understanding complexity in data-intensive societies. Communicating to wider publics, though, requires that authors intentionally shape sonification in ways that consider the goals and contexts in which publics relate. It requires a specific set of knowledge and skills that design as a discipline could provide. In this article, we interpret five recent sonification projects and locate them on a scale of intentionality in how authors communicate socially relevant issues to publics.
