Audio media offers a rich source of historic ethnographic information, with the earliest forms of recorded sound dating back to 1890.[1] According to the International Association of Sound and Audiovisual Archives (IASA), these sources of audio data, as well as the aging technologies used to play them back, are in imminent danger of permanent loss due to degradation and obsolescence.[2] These primary sources are called “carriers” and exist in a variety of formats, including wax cylinders, magnetic tape, and flat discs of grooved media, among others. Some formats are susceptible to more severe, or quicker, degradation that others. For instance, lacquer discs suffer from delamination. Analog tape may deteriorate due to sticky shed syndrome.
I'd like to add information specifically pertaining to audio digitization, form legacy formats (analog tape) to a digital copy. I would like to focus on archival standards and procedures, notable institutions, and the progress of technology as it pertains to audio digitization.
