Henri Chamoux is known all over the world, in his specialized field, for his invention, the Archéophone, in 1998, a modern-day version of the early 20th century gramophone. This apparatus is the only modern device that can digitalize phonographic cylinders of any format, as from 1888, without damaging them. Many libraries and archives in the world are equipped with this device, such as the French National Library or the Congress Library in the United States.
Not stopping at this invention, Henri Chamoux launched another big project: creating the Phonobase, online discs and cylinders from the Belle Epoque. This web base has given increased public access to more than 10,000 audio materials produced before 1914! Finally, another big project, using the Archéophone, is the digitalization of the recording of Nelson Mandela’s trial, initially engraved on flexible cylinders between 1963 and 1964.
Henri Chamoux also wrote a thesis «The broadcasting of sound recordings in France and in the Belle Epoque (1893-1914), artists, industrialists and auditors of cylinders and disc material». Submitted at Paris I university in 2015, his work received the highest distinction. As a recognized expert in the digitalization of sound archives, the inventor, today, runs training courses on this subject.
