 while being photographed onto it to produce a continuous soundtrack. Afterwards this filmstrip is played as a normal movie by means of a film projector. Being read by photocell, amplified and monitored by a loudspeaker, it functions as a musical recording process.

Although with the first version of the Variophone, polyphonic soundtracks of up to 6 voices could be produced by shooting of several monophonic parts and combining them later, by the late 1930s and 1940s, some soundtracks contained up to twelve voices, recorded as tiny parallel tracks inside the normal soundtrack area.

At the same time in the Soviet Union several other artists were experimenting with similar ideas. The first artificial soundtrack ever created was drawn in 1930 by composer and musical theorist Arseny Avraamov who was working with a hand-drawn technique for producing sound effects. Nikolai Voinov, Ter‐Gevondian and Konstantinov were developing paper sound techniques. Boris Yankovsky was developing his spectral analysis, decomposition and resynthesis technique, resembling the recent computer music techniques of cross synthesis and the phase vocoder.

Many sound films and artificial soundtracks for movies and cartoons were produced by means of the Variophone, including the popular sound-films, often broadcast in 1930-1940-s Symphony of the Piece and Torreodor. At the end of 1941 Siege of Leningrad
