an interactive musical system in-progress characterized by:

real-time identification and classification of percussive (and “extended”) sounds
correspondences between Schaeffer’s perceptual criteria and low-level audio descriptors
applications: performance practice and analysis, creative projects
implementation in Max 8 (PureData version coming soon)

sound samples used in the papers

Anesidora (2022) – a percussion duo with live-electronics – composed by Caio Campos using descriptors from obié.

Improvisation with a frog-guiro (2022) – different sounds played on the guiro are analyzed, processed, and transcribed; the sound output is sent to one pandora (a snare-drum with an embedded loudspeaker).

Pandagora (2023) – a musical meeting around the pandora snare-drum. Participants: a dancer with IMU sensors and three musicians. Kalimba, guiro, and vocal sounds are fed into Obié and go through different sound processes. The gestural activity of the dancer is mapped into diverse processes of sound synthesis.
