Fritz Pfleumer patent in Germany for application of magnetic powders to strip of paper or film. Minnesota Mining and Manufacturing began tape coating experiments in U.
Our past accomplishments contribute to what we are today, and signpost the future as a never-ending quest to push the envelope of what is possible in audio. In the Committee for the Fiftieth Anniversary of the AES was formed to increase the awareness of where we have been and what we have accomplished.
It is intended to be a selection of significant events, inventions, products and their purveyors. This Timeline is not complete, and probably never could be, given the wealth of discoveries, inventions and innovative products that did and do appear almost daily.
Nor are the dates given always precise, depending as they often do on second hand documents or dim memories. Its authors would welcome any substantiated corrections or additions to this timeline, for imperfect as it must be, it serves as both backbone and DNA in the evolution of our industry.
Please send your comments to us. We hope you will return to this page often to check on the evolution of our Timeline, as the first of many pieces to be generated by the Historical Committee as this Site expands. He demonstrates his invention in the offices of Scientific American, and the phonograph is born.
Experimental optical recordings are made on motion picture film. Armstrong is issued a patent for a regenerative circuit, making radio reception practical.
Wente of Bell Telephone Laboratories publishes a paper in Physical Review describing a "uniformly sensitive instrument for the absolute measurement of sound intensity" -- the condenser microphone.
It is owned in part by United Fruit. This all-acoustic player -- with no electronics -- is considered a leap forward in phonograph design. The first electrically recorded 78 rpm disks appear. RCA works on the development of ribbon microphones. Harold Black at Bell Labs applies for a patent on the principle of negative feedback.
It is granted nine years later. Georg Neumann founds a company in Germany to manufacture his condenser microphones. Its first product is the Model CMV 3.
His seminal patent discusses the theory of stereo, both describing and picturing in the course of its odd individual claims a coincident crossed-eights miking arrangement and a "" cutting system for stereo disks. Arthur Keller and associates at Bell Labs in New York experiment with a vertical-lateral stereo disk cutter.
Olson of RCA, using a field coil instead of a permanent magnet. Snow, Fletcher, and Steinberg at Bell Labs transmit the first inter-city stereo audio program.By Roger Beardsley and Daniel Leech-Wilkinson.
In the beginning. The story of sound recording, and reproduction, began in , when the man of a thousand patents, Thomas Edison, invented the phonograph.
- Edison made the first recording of a human voice ("Mary had a little lamb") on the first tinfoil cylinder phonograph Dec. 6 (the word "Halloo" may have been recorded in July on an early paper model derived from his telegraph repeater) and filed for an American patent Dec.
The 50th anniversary of the Beatles on the Ed Sullivan Show is approaching. You may ask why the Beatles important to Music History. Here's some reasons. The Recording Industry Association of America (RIAA), the record industry's lobbying and trade organization, continues its fight for taxes on blank tapes into the s and legislators eventually.
Audio files play a significant role in our society nowadays, and therefore I think it is important to know a little about the history of recording.
The word Phonautograph is a neologism, by the way, and literally, means “sound-itself-writer.”. the Fletcher-Munson Curve from Bell Labs audio research The Development of Electrical Recording at Bell Laboratories Radio broadcasting in the United States began in November, when KDKA, Pittsburgh was granted its call letters and began broadcasting regardbouddhiste.com development represented a challenge to the phonograph, since free music and entertainment was available "off the air".
