Where are the files of my immersive production and why don't they open correctly on another DAW? This workshop will outline some of the major challenges when working with archival materials and it will discuss ongoing activities in AES Standards Group SC-03-06 relating to multi-track and multi-channel audio. The workshop will give an overview of the status of the document, "Implementation of a Recommended Workflow for the Creation and Archiving of Digital Archival Materials from Professional Audio Production Formats," as well as why the interaction with related partner institutions (NARAS P&E Wing, SMPTE) and internal working groups is so important. The topic is relevant not only for preservation in an archival setting, but far beyond, for keeping audio productions safely stored and accessible in general.
