This morning, NIMSE and CMUS invited academic Javier Osorio to give a talk called “Sound Recording as Document and Problem” at the CIAH of Universidad Mayor, as part of NIMSE’s series of talks on problems of sound/listening. At the meeting, the researcher from Alberto Hurtado University addressed perspectives on methods of recording ethnographic work from the 20th century, asking questions such as “What practices enable listening to a recorded event?” and “What temporalities emerge in the power of the sound archive?”
