Synopsis "Phonofilm"

High Quality Content by WIKIPEDIA articles! In 1919, Lee De Forest, inventor of the audion tube, filed his first patent on a sound-on-film process, DeForest Phonofilm, which recorded sound directly onto film as parallel lines. These parallel lines photographically recorded electrical waveforms from a microphone, which were translated back into sound waves when the movie was projected. Some sources say that DeForest improved on the work of Finnish inventor Eric Tigerstedt -- who was granted German patent 309.536 on 28 July 1914 for his sound-on-film work -- and on the Tri-Ergon process, patented in 1919 by German inventors Josef Engl, Hans Vogt, and Joseph Massole.
