Surround Sound History

1894 The Kinetaphone 
(Developed by -Military - Communication)
Invented by: Thomas Edison
- Edison company experimented with this machine.


The Edison Company is known to have experimented with this as early as the fall of 1894 under the supervision of W. K. L.
W.K.L Dickson Invented- The "Dickson Experimental Sound Film"

 (A pullie linking them together )- 


1913, a different version of the Kinetaphone was introduced to the public.
 The sound was made to synchronize with a motion picture projected onto a screen. A celluloid cylinder record measuring 5 1/2" in diameter was used for the phonograph. 

Beginning Of Sound
1- Live Piano Music - Charlie Chaplin 

1926 - Don Juan - Music Only- No Dialogue
1927 - The Jazz Singer - 1st synchronize Film -Vinyl recording  
Famous Line "Wait A Minute" You ain't heard nothing yet"   


 
The term Sound-on-disc refers to a class of sound film processes using a phonograph or other disc to record or playback sound in sync with a motion picture. Early sound-on-disc systems used a mechanical interlock with the film projector, while more recent systems use timecode.

Note- So it a term for the name of the sound/film process which they created through different inventions of syncing sound to film . 
Sound-on-disc processes:

The Vitaphone
First "SOUND ON DISC" Technology used to bring audio/dialogue to film
Developed by Bell Labs and Western Electric Sounds

 1930'S Experimented with Centre Speaker L C R 


CON OPT -OPTICAL SOUNDTRACKS -COMPOSITE OPTICAL
ACADEMY OF MOTIONS PICTURES 
ARTS AND SCIENCE (AMPAS)
They created a new film standard
AUDIO ADDED TO THE FILM Strip (35mil)- FREQUENCY AND AMPLITUDE

- MAGNETIC- 1950's 6 Channels  TOD A.O (70 mil) larger. BOTH SIDES OF THE FILM STRIP!
(today they use this format in IMAX )

OPTICAL FILM- the magnetic strip they use today for showing films. 


1. Variable Area Sound Track
2 Variable density  
 opacity - lighter and darker and  frequency / amplitude 
(Today we use stereo optical sound tracks )


1939- THE ACADEMY CURVE  or( The N Curve- Normal)
AMPAS - Brought it in to improve the audio quality, before 1339 there was no standard of quality.

Thet created a way to treat the sound


Flat 100Hz - 1.6 kHz down 7 db at 40 Hz, down 10 db and 5Hz down 18 db at 8 kHz

FANTASOUND 

1940'S Pre -LCRS output format 
Walt Disney - Made Surround Sound
Lee Polls Sakouski- German Developed (Soundtrack developer)

- Click track
- pan pots
-simultaneous multi tracking 4 track system
