The Body & the Archive: Towards a Sonic Speculation is a participatory performance exploring how sound generation can become a form of remembrance and renewal. Using wearable biosensors, the apparatus employed by affective computing to infer emotional status, it transforms participants’ physiological rhythms, such as pulse, into sound, weaving them together with AI-generated sonic material trained on audio recordings of historic socio-political events. The result is a shifting acoustic environment where personal and collective intensities merge, inviting audiences to experience the interdependence between body, technology, and memory. The performance asks rather than statistical analysis, generalization, classification, and patterning, how machine learning corelated with sensing—both through sensors and through the body’s sensory receptors—can serve as a means of connecting to histories of resistance, vulnerability, and care.The Body & the Archive: Towards a Sonic Speculation is a participatory performance exploring how sound generation can become a form of remembrance and renewal.
