Abstract

Digital preservation is a necessary tool to achieve the integral and lasting preservation of all types of document files, especially sound files, vulnerable documents to technological changes, which when recorded and processed on specific media, quickly become obsolete. The objective of this systematized review was to identify the digital preservation strategies used in the preservation of sound resources and their applications according to its format. The bibliographic search was carried out in twelve multidisciplinary databases, selecting 16 articles for research, from which eleven digital preservation strategies were identified. It concluded that the most used strategies are migration, preservation metadata, backup copies and emulation. On the other hand, it was not possible to establish an application parameter for digital preservation strategies according to the type of format of the sound files.
