A brief history of sound recording

1. MUSIC AND MEDIA

2.  Sound recording is the storage of sounds so that they can
be heard again.
 Sound recording is also used in radio, television, and
movies.

4.  In 1877 the American
inventor Thomas
A.Edison demonstrated
the first “talking
machine”, which could
both record and
reproduced sound.
 Before the phonograph
was invented, people
only had entertainment
by live musicians and
actors. This invention
allowed people to have
music anytime.

5.  The term Phonograph means “writing sound”, a
term coined from Greek roots.
 Edison’s early phonographs recorded on a wax
cylinder using up-down (vertical) motion of the
stylus.

6. Emile Berliner invented what he called the
Gramophone, another device for recording
and replaying sound, and patented it in 1888.
It recorded on a disk using side-to-side
(lateral) motion of the stylus.

8.  The long-playing microgroove vinyl record, or
“LP”, was developed at Columbia records and
introduced in 1948.
 Vinyl records were lighter and less fragile than
shellac records.
 The Magnetophon tape recorder was one of the
first recording machines to use magnetic tape in
preserving voice and music. The Magnetophone
became a high fidelity recording system that
outperformed gramophone recording.

10.  In digital recording, digital audio is directly
recorded to a storage device as a stream of
numbers, representing the changes in air pressure
through time, thus making an abstract template
for the original sound.
