IASA 2019 Annual Conference

Co-edited by Will Prentice and Lars Gaustad, this is the 4th Edition, published in 2017. While the earlier versions concentrated on audio, this new edition is extending these general principles and strategies to include moving images. The tutorial concentrates on the content migration for audio and video documents, the only viable method to preserve their contents in the long-term, because of the instability of original carriers and the obsolescence of replay equipment. The principles of optimal signal extraction from original carriers, unmodified transfer to digital archival formats, and the importance of metadata for the authentication of contents will be discussed.
