This cylinder may be able to answer an enduring mystery about the John F. Kennedy assassination.

WASHINGTON, Aug. 2 - About a year from now, one of the most vexing mysteries in American history may finally be solved: Did Lee Harvey Oswald act alone?
Scientists at the Lawrence Berkeley National Laboratory have begun work on a digital scanning apparatus that they believe will be able to reproduce sound from the only known audio recording of the assassination of President John F. Kennedy on Nov. 22, 1963, in Dallas.
The recording was made through an open microphone on a police motorcycle during Kennedy's motorcade into Dealey Plaza, where the president was shot to death. The sounds were captured onto a Dictaphone belt at police headquarters, but scientific analyses of them over decades proved anything but conclusive, fueling arguments about how many people were actually involved in killing the president.
The federal government's official inquiry into the assassination, the Warren Commission, concluded in 1964 that Oswald was a lone gunman, firing three shots from the Texas Book Depository building high above the plaza. But a House committee that investigated the shooting 15 years later concluded that four shots were fired, including three from the book depository and one from another location, giving rise to all manner of conspiracy theories.
Like old 78 r.p.m. records, the Dictaphone belt became worn and damaged through constant replay for analysis using a stylus. When it became property of the National Archives in 1990, the technical staff recommended that no further efforts be made to replicate its sounds through mechanical means.
That left preservationists with a daunting and historically important challenge: How could the sounds on the old plastic belt be captured for posterity, and if they could, would they provide unequivocal evidence of how many shots were fired?
Leslie C. Waffen, an archivist with the National Archives, said he believed not only that the sound could be captured but also that, using digital analysis to map the sounds, scientists could remove extraneous noise like static and distant voices to reveal gun shots.
"This is big," said Mr. Waffen, whose unit has custody of the belt as well as the original 8-millimeter home movie by Abraham Zapruder, which showed the assassination in color but utter silence. "That's why we called the experts in. They came up with a recommendation to do this."
After a June meeting of the National Archives Advisory Committee on Preservation, the job was left to Carl Haber and Vitaliy Fadeyev of the Berkeley laboratory, who have used a digital optical camera to replicate sounds on fragile Edison cylinders and long-play records. The process involves scanning the grooves of the Dictaphone belt electronically to create a digital image of the sound patterns.
Once that is achieved, Mr. Waffen said, the scientists could "clean it up, like peeling layers off an onion to get down to the sound floor" of the recording. And that, he said, could reveal how many shots were fired.
It is a question that has bedeviled government officials, law enforcement agents and historians since the actual event, leading to an array of conspiracy theories involving the mob, Fidel Castro, Lyndon B. Johnson, Russians or, as the film director, Oliver Stone, would have audiences believe, the "military industrial complex."
Among the strongest and most persistent alternative theories to the Warren Commission report has been the involvement of a second gunman on a sweep of land above the motorcade route that came to be known as the grassy knoll. It gained widespread currency after the 1979 Congressional investigation, which relied, in part, on a graphic comparison of the sounds on the Dictaphone belt and a test of gunshots in Dealey Plaza.
They produced evidence that four shots were fired, with indications that the first, second and fourth shots came from the book depository and the third came from the grassy knoll.
But three years later, in a subsequent acoustical analysis, the National Academy of Science concluded that the noise that others ascribed to gun shots was merely static or something else. That was the last time the belt was played.
Once it became the belt's custodian, the National Archives was faced with two questions: What should be done with it? And how could its evidence be accurately captured and made public?
For years, the questions were unanswered, until it became clear that new technologies might produce evidence that was unreachable through older, less sophisticated analytical methods that risked further damaging the belt.
The advisory commission concluded that the National Archives had a responsibility to provide a true copy of the sound, if not enhance it. That, the panel members said, could be left to the researchers.
"People want to know," said Gary Mack, curator of the Sixth Floor Museum at Dealey Plaza, which opened in the book depository building in 1989. "The Warren Commission said it was one guy. The House Committee said it was Oswald and someone else. There hasn't been any resolution."
Mr. Waffen said it was about time to get one.
"Scientists have studied these sounds for 25 or 30 years and have still reached different conclusions," he said. "But with today's technology, we can get a better reading and answer the question, one way or the other."

With the headline, I first thought about Mary Jo Kopechne and Chappaquiddick. My bad...different killing.
"With the headline, I first thought about Mary Jo Kopechne and Chappaquiddick. My bad...different killing."
LOL I thought the same thing.
Seriously though. I know people that have worked on the 1979 recording and cannot find ANY shots let alone four. There is just too much noise.
I will always believe that there were at least two other gunmen and LHO was just a patsy that may have gotten off one lucky shot.
Interesting........
Oh goody, I love this stuff.
Totally off topic, but your picture reminded me of something funny I heard yesterday.
I was listening to Glenn Beck's show, and Glenn kept pretending to dial up Kerry to ask questions about his flip-flopping, etc.
Everytime they'd call Kerry's number, they played a "tape" of Kerry's answering machine saying;
"Hi, this is John Kerry. I'm not home right now, I'm out at a farm, with a gun, standing in front of a flag. Leave a message."
Sorry for the OT, but it's your picture's fault, LOL.
Read:
"Six Seconds in Dallas"; "Best Evidence"
Anyone that beleives Oswald acted alone is not dealing with the real world to well.
I have read over 50 books on this subject.
LOL. And you think we're not dealing with the real world?
I want to know who decides what gets sealed in the National Archives for 50-75 years!
2. These guns were fired in coordination
3. ever watch a 21 gun salute when 7 guns fire at the same time and sound like one shot....
No matter what anyone ever tells you, The Wizard Commission Report, documented that at least 7 shots were fired at the Limo, and the famous dictabelt shows at least that many.......
Oswald shot no one, and the shots from the Manlicer Carcano, fired only to implicate the patsy, HIT NO ONE: The street and the grass across the street.
That was really funny! Thanks!
LOL
Interesting that someone at the National Archives is still investigating this.
My guess is that it'll show exactly what *they* want it to show, whomever *they* really are. No surprises are scheduled.
