Today, we are highlighting one of the State Archives’ exciting endeavors: audio digitization.
Since 2003 the State Archives has digitized thousands of audio recordings in the Florida Folklife Collection. The goal of this effort is to preserve Florida’s folk culture and make it accessible to educators, researchers, and Florida folk enthusiasts around the world. The Collection includes interviews, field recordings and performances gathered by folklorists from the Florida Folklife Program and recordings from the Florida Folk Festival dating back to 1954.
Audio recording formats in the Folklife Collection consist of reel-to-reel tapes, cassette tapes, digital audio tapes (DATS), compact discs (CDs), and digital audio files. They are kept in a temperature and humidity controlled environment in the Archives’ stacks to minimize deterioration.
To bring you these recordings, the original source materials must be transferred from their analog medium to a digital file. This process requires legacy audio equipment, like reel-to-reel tape machines and cassette decks, to play the audio recordings, and new digital technology, such as analog-to-digital converters, high quality sound cards, and audio computer software to capture the sound digitally.
The resulting digital audio file is an uncompressed 96 khz 24 bit WAV file. This file specification is a national archival standard, chosen for its ability to capture all frequencies in the human hearing range.
These high quality files are called “preservation masters” and are stored without undergoing any editing whatsoever. The idea is to preserve all sonic qualities (good and bad) of the original recording. Some recordings undergo minor editing for listenability when making access copies (e.g. CDs) for users, and mp3 versions for the Florida Memory website and Florida Memory Radio.
