Anthropological studies rarely make use of sound archives, despite their value as historical sources. The neglect arises from the absence of systematic documentation activities on the numerous recordings made by prior anthropologists/ethnomusicologists. In addition, researchers in ex-colonial state frequently encounter difficulties accessing record archives due to the closure of vital resources that have been created in Western countries with established archive infrastructure and institutions. This session provide an introduction to the significance of sound archives in the field of anthropology and the activities of Pratinada, an archiving platform that has been developed as part of the Decolonizing Sound in Southeast Asia project (DECOSEAS). The Workshop is organized by Imam Ardhianto, Hestu Prahara (Universitas Indonesia), Pierre Prouteau (Nanterre University) and Joséphine Simonnot (PRISM, CNRS).
