This is the second episode of a two-part interview with Dr. Nadja Wallaszkowits, the Head Sound Engineer of the Phonogram Archive of the Austrian Academy of Sciences. This episode focuses on Nadja’s and my reflection on how the development of audio recording and technology shifted the questions we ask about sound, and how they shaped our listening aesthetics. I asked Nadja, how does the knowledge in the science of sound recording and engineering shape the questions that we ask about sound? How did it change our listening aesthetics? The microscope enabled us to see things that we could not see before. How did sound recording technologies allow us to hear things that we would not have been able to hear before, and how did this change how we understand our world?    Dr. Nadja Wallaszkovits managed the audio department as a specialist for audio restoration, re-recording and digital archiving and is consultant for archival technology for various institutions internationally. Dr. Wallaszkovits is Audio Engineering Society (AES) President Elect, Vice Chair of the Technical Committee of the International Association of Sound and Audiovisual Archives (IASA), and a member of the IASA Training & Education Committee. Since 2020, she was appointed Professor of Conservation and Restoration of New Media and Digital Information at the Stuttgart State Academy of Art and Design.    Sonic Entanglements is hosted and produced by meLê yamomo. Thijs van den Geest is our sound engineer and sound editor, and Jean Barcena is our publicity manager.
