Mark Holland, who works at a recording studio and restores recordings on a freelance basis, was at the lecture and described the technology as “magnificent.” Since then, Fadeyev and Haber have restored old recordings of Thomas Edison, a previously unconfirmed recorded outtake of Elvis Presley’s “Jailhouse Rock” and other early 20th century recordings that had previously been too damaged to play. They named the machine Image Reconstruct Erase Noise, Etc., or IRENE.įadeyev said IRENE’s name was a tribute to the song on which they first used their technology. The physicists then began building a machine for the SmartScope scans. The original recording was full of static and was distorted from age and deterioration, but when the digital scan was used to play the song, the sound was clear and free of distortion. When Fadeyev and Haber began their work, they went to a used record store and purchased a 78-rpm disc of The Weavers’ “Goodnight Irene.” He said once they realized what was possible with the technology, they began to study the mechanics of recording sound to help their restoration work. “We played with this idea, but we didn’t know what to expect,” Fadeyev said. Haber and Fadeyev had previously used the technology to track the subatomic particles set free in physics experiments.Īfter the digital images of the recordings were created, Fadeyev wrote a computer program that duplicates the movement of a record player stylus to create digital copies of the sound on the record.įadeyev said that he and Haber got the idea for the project when they heard a news story about old recordings that were damaged and in need of restoration and preservation. The SmartScope then builds a digital image of the grooves. The microscopic grooves in the recordings are scanned using a digital microscope called a SmartScope. The restoration process is unlike any previous attempts at restoring old recordings because it does not require the recordings to be played.
