History of Audio

What is audio? Definitions of audio ….

Of or relating to humanly audible sound. Of or relating to the broadcasting,

reproduction, or reception of sound. Of or relating to sound or hearing audio

frequency. (Electronics) relating to or employed in the

transmission, reception, or reproduction of sound.

What is sound? Definitions of sound….

Transmitted vibrations of any frequency. The sensation stimulated in the organs

of hearing by such vibrations in the air or other medium.

Audio and Sound Sound is basically vibrations in the air, Audio is reproduction, or reception of

sound. So you have to hear sound to be able to

recognize audio.(So you cant be deaf, but I'm pretty sure deaf people find away to enjoy audio, like Beethoven did which was by feeling different vibrations made by different notes and putting them together to make all of his BRILLIANT music.)

When was audio discovered? "Au Clair de la Lune, Pierrot repondit...".

Worlds first audio recording ever made on April 9, 1860 (17 years before Thomas Edison's ). The audio recording was a verse of "Au Clair de la Lune", was made by Frenchman Édouard-Léon Scott de Martinville who invented the phonautograph.

When was sound discovered? The first device that could record actual

sounds (but could not play them back—the purpose was only visual study) was the phonautograph, made in 1857 by Parisian inventor Édouard-Léon Scott de Martinville.. The first device that could record actual sounds (but could not play them back—the purpose was only visual study) was the phonautograph, made in 1857 by Parisian inventor Édouard-Léon Scott de Martinville..

1857 In 1857, Édouard-Léon Scott de

Martinville invented the phonautograph, the first device that could record sound waves as they passed through the air.

1877 In 1877 another inventor, Charles Cros,

said that the process could be reversed by using photoengraving to convert the traced line into a groove that would guide the stylus, and sent back into the air as sound.

1878 The music is first put on record:

cornetist Jules Levy plays "Yankee Doodle."

1881 Clement Ader, using carbon

microphones and armature headphones, accidentally makes a stereo effect when listeners outside the hall monitor connect telephone lines connected to stage mikes at the Paris Opera.

1887 An inventor from America soon saw that

idea, and in 1887 that yet another inventor, Emile Berliner, actually photoengraved a phonautograph recording into metal and played it back.

1888 Edison invents a electric motor-driven

phonograph.

1895 Marconi successfully experiments with

his wireless telegraphy system in Italy, leading to the first transatlantic signals from Poldhu, Cornwall, UK to St. John's, Newfoundland in 1901.

1898 Valdemar Poulsen markets his

"Telegraphone," which records audio magnetically on steel wire.

1900 Poulsen shows his invention to the

public at the Paris Exposition. Austria's Emperor Franz Josef records his congratulations.

1901 The Victor Talking Machine Company is

founded by Emile Berliner and Eldridge Johnson.

Experimental recordings are made on motion picture film.

1906 Lee DeForest invents the triode vacuum

tube, the first electronic signal amplifier.

1913 The first "talking movie" is showed by

Thomas Edison using his Kinetophone process, a cylinder player mechanically synchronized to a film projector.

1878- 1916 The Dictaphone was basically wax

cylinders for voice recording made the Volta Laboratory and established by Alexander Graham Bell in Washington, D.C.

1934-1935 The world's first tape recorder built and

used for broadcasting. He later made the first consumer tape recorder called the Sound Mirror.

1931 William Schergens created the first

answering machine.

1939 Engineers in Germany, Japan and the

U.S. discover and develop AC biasing for magnetic recording.

1948 Magnecord introduces its PT-6, the first

tape recorder in portable cases.

1962 The first compact audio-cassette was

invented and released by the Philips Company .It recorded and played back audio at a speed of 1.7/8 inches per second.(not really called-for…)

1963 Philips introduces the Compact Cassette

tape, and offers licenses worldwide.

1964 Stereo 8 (also called eight-track

cartridge, eight-track tape, or eight-track) was created by Bill Lear along with Ampex, Ford Motor Company, General Motors, Motorola, and RC Victor Records.

1975 Michael Gerzon builds the Sound Field

microphone.

1979 Philips demonstrated a prototype of a

readable CD-ROM for computers.

1994 At the age of 13, Garrett recorded two

CDs.
