For sound pickup, the Tri-Ergon system utilized a dynamic microphone without mechanical moving parts (Katodophone) and a variable density recording tube with an electric discharge.]]> 2022-02-14 12:25:26 UTC https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046072883 yiwu20251 https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046076090 Edward C.

In 1919, DeForest Phonofilm, a variable density film system, was developed by Case Labs of Auburn, NY. After years of legal troubles with Case and others, DeForest left the business.]]> 2022-02-14 12:50:59 UTC https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046116944 yiwu20251 https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046124706 It was Thomas Edison's work on the telegraph and the telephone that led to the development of the phonograph. Edison was working on a machine in 1877 that would transcribe telegraphic messages through indentations on paper tape, which could then be repeatedly sent to recipients. This development led Edison to speculate that a telephone message could also be recorded in a similar fashion. He experimented with a diaphragm which had an embossing point and was held against rapidly-moving paraffin paper. ]]> 2022-02-14 12:55:04 UTC https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046124706 yiwu20251 https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046133447 It was Fox's single-system camera they used for their feature films until 1931 (after which they switched to RCA photophones), but it was Fox Movietone news they continued to use until 1939 because of the convenience it provided for news gathering. There was only one cameraman and one soundman on crew, and all of the gear could be hauled in the same recognizable news truck, just like modern ENG newsgathering.]]> 2022-02-14 13:00:18 UTC https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046133447 yiwu20251 https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046136241 Sam Warner strongly believed in sound films, and used the Vitaphone recorded disc system. Among the greatest early sound artists was George Groves, who recorded this film. Up to fifty discs were recorded for one reel of film, then in an elaborate electrical synching system they were remixed together to run in synch with the film when played on the single release disc for the movie theaters. The Jazz Singer was the first feature film w/synch dialogue]]> 2022-02-14 13:01:55 UTC https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046136241 yiwu20251 https://padlet.com/yiwu20251/vcxhevy13t4x7llg/wish/2046143194 A new microphone type was again launched in the late 1920's by E.C.

Although the Nagra debuted in the US ten years earlier, much work was done to make the recorders run synch with film, which was finally achieved with the Nagra III. (a compact, 11-pound mono 3.75/7.5/15 ips reel-to-reel deck with neopilot sync). Nagra means "will record" in Polish. Stefan Kudelski was the very young inventor, born in Poland.

• The 4.2 was similar to the IV-L, but added phantom power for microphones and built-in equalizers. The first stereo Nagra field recorder (pictured) was the IV-S, It had dual level pots, limiters, and equalizer presets. It was introduced in 1971. Originally it was available with a pilottone crystal, and then in 1984, with timecode capacity. With timecode support an IV-S became a Nagra IV-STC.

This version of the Nagra kept a time code signal running, and so when the sound rolled, then the camera rolled, it saw the numbers racing on the slate and there was no need to record a clap of the slate. In post production the numbers from the time code on the auxilliary audio track were matched with the numbers on the slate frames, and wallah you have synch.

As of 2009, the two most popular current location film recording devices are the Aaton Cantar and the Fostex PD6. Both machines record sound files and also generate time code that can be used to keep film and audio in synch.
