step optical reconstruction for 78-rpm records [3]. First, a 2D analog camera is used to rapidly photograph the records and the images are preserved on film. This film is then scanned and digitized into 2D digital images, which are further analyzed to extract the audio. During the scanning, the film is placed on a rotating tray with an

Creating an optical audio reconstruction of records is a well researched topic where different methods and approaches have been studied and proposed for a few decades. In a historical perspective, the first contact-free approach for reading records was presented by William K. Heine [Heine, 1976]. The proposed procedure is
