IRENE Audio Preservation Service now available at NEDCC

19 Nov 2014 1:56 PM | Iona McCraith (Administrator)

Northeast Document Conservation Center now welcomes audio preservation projects for reformatting grooved media using the new IRENE technology.

The IRENE audio preservation service at NEDCC is the culmination of a decade of research and development at the Lawrence Berkeley National Laboratory and the Library of Congress.  IRENE uses a non-contact approach, which eliminates the possibility of damage caused by mechanical contact of a stylus on fragile media.  The process creates ultra-high resolution images of the audio groove structures in either 2D or 3D, as required.  The resulting image files are then processed through software that translates them into an audio file. 

NEDCC Currently Works with the Following Formats:

  • Wax cylinders
  • Lacquer discs (a.k.a., “acetate” discs)
  • Aluminum transcription discs
  • Shellac discs
  • Tin foils
  • Other rare formats (e.g., Dictabelt, Voice-O-Graph, etc.)
