HISTORY OF RECORDING

First Steps - the Telephone

In the 1840s, an Italian called Antonio Meucci discovered the basic principles of the telephone, and he was able to make a public demonstration of the technology in 1860 in New York, in which the voice of a singer was transmitted.  In the late 1860s, his working models were sold to an unknown buyer by his wife while he was in hospital after a serious accident.  He rebuilt them, and in the early 1870s, while trying to get the $250 required to file a full patent, he sent details to the US patent office with a notice of intention to file a patent.  A few years later in 1876 the telephone was patented by Alexander Graham Bell, whose name has been associated with it ever since.  Meucci sued, and was close to winning in the supreme court when he died.  Other inventors with claims to priority over Bell are Elisha Gray (USA) who submitted a caveat for a patent application about two hours before Bell's full application was received (though it wasn't entered in the records until about two hours after Bell's), Johann Philipp Reis (Germany), and Charles Bourseul (France).

In 1881, microphones were set up in the Paris Opera, each feeding eight earphones.  Pairs of microphones were set up on the left and right of the stage, and the earphones fed by each pair were held to the left and right ear of the listener.  It was noted that this gave both a clearer perspective of distance and the ability to discern the movement of singers across the stage.  Thus stereo was invented only five years after Bell's patenting of the telephone itself, though it was promptly forgotten about.

First Steps - Mechanical Recording

In 1877, Edison made the first successful recording, using a stylus attached to a diaphagm to make indentations in tinfoil wrapped round a cylinder.  Subsequently, he started using wax as the recording medium.  A few years later Berliner invented ways of recording on disks, and he was the first to be able to mass produce recordings - an essential development for distribution and sale.  Cylinders and disks were both made and sold until Edison changed to the disk format in 1913.

These systems were purely mechanical, using horns to concentrate and project the sound during both recording and playback.  The electrical signals used in telephones were not strong enough to be used in recording and playback.  As a result, the recording of a solo voice or instrument was the most effective use of these systems, and accompaniments were often very indistinct.  It is remarkable what fidelity was achieved with the voice, however.

A sideline which was also very successful for a time was the mechanical recording of piano playing, from which rolls were made which could be played back on real pianos. This neatly avoided the lack of power and fidelity in acoustic recordings, but brought its own limitations in a lack of dynamic and rhythmical exactness.  However, the recordings could be edited - which was not then possible for sound recordings.

Both acoustic sound recordings and the player-piano rolls were very successful in the marketplace, with the result that we have a good record of a somewhat limited musical repertoire from the beginning of the twentieth century.

Bringing it together - Electrical Recording

The development of electrical amplification around the time of the first world war was naturally applied to sound reproduction; but in spite of radio and the invention of the condensor microphone during that decade, it was not until 1925 that commercial records were made electrically rather than acoustically.

Early attempts to record electrically also included methods of recording on a moving photographic film, thus starting the association of sound recording with movie technology which has been important ever since.
