Above, the Presto Model A, their top-of-the-line system circa There is a detailed history of the Presto Corp provided at this website, so no need to re-tread those waters. Basically, what Presto offered was a way to make good-sounding LP and 78 recordings that could be played back instantly on any home turntable.

On April 30,French poet, humorous writer and inventor Charles Cros submitted a sealed envelope containing a letter to the Academy of Sciences in Paris fully explaining his proposed method, called the paleophone.
Recording of Bell's voice on a wax disc inidentified in [more details] Emile Berliner with disc record gramophone The next major technical development was the invention of the gramophone recordgenerally credited to Emile Berliner and commercially introduced in the United States inthough others had demonstrated similar disk apparatus earlier, most notably Alexander Graham Bell in Sales of the gramophone record overtook the cylinder ca.
Edison, who was the main producer of cylinders, created the Edison Disc Record in an attempt to regain his market. In various permutations, the audio disc format became the primary medium for consumer sound recordings until the end of the 20th century, and the double-sided 78 rpm shellac disc was the standard consumer music format from the early s to the late s.
Although there was no universally accepted speed, and various companies offered discs that played at several different speeds, the major recording companies eventually settled on a de facto industry standard of nominally 78 revolutions per minute, though the actual speed differed between America and the rest of the world.
The specified speed was The difference in speeds was due to the difference in the cycle frequencies of the AC electricity that powered the stroboscopes used to calibrate recording lathes and turntables.
Discs were made of shellac or similar brittle plastic-like materials, played with needles made from a variety of materials including mild steel, thorn, and even sapphire.
Discs had a distinctly limited playing life that varied depending on how they were produced. Earlier, purely acoustic methods of recording had limited sensitivity and frequency range.
Mid-frequency range notes could be recorded, but very low and very high frequencies could not. Instruments such as the violin were difficult to transfer to disc. One technique to deal with this involved using a Stroh violin to which was fitted a conical horn connected to a diaphragm that vibrated due to the violin bridge.
The horn was no longer needed once electrical recording was developed. The short-playing but convenient 7-inch 45 rpm microgroove vinyl single was introduced by RCA Victor in In the US and most developed countries, the two new vinyl formats completely replaced 78 rpm shellac discs by the end of the s, but in some corners of the world, the "78" lingered on far into the s.
Vinyl was much more expensive than shellac, one of the several factors that made its use for 78 rpm records very unusual, but with a long-playing disc the added cost was acceptable and the compact "45" format required very little material.
Vinyl offered improved performance, both in stamping and in playback. If played with a good diamond stylus mounted in a lightweight pickup on a well-adjusted tonearm, it was long-lasting. If protected from dust, scuffs and scratches there was very little noise.
Vinyl records were, over-optimistically, advertised as "unbreakable". They were not, but they were much less fragile than shellac, which had itself once been touted as "unbreakable" compared to wax cylinders. Electrical recording[ edit ] RCA, a classic ribbon microphone introduced in Similar units were widely used for recording and broadcasting in the s and are occasionally still used today.
Between the invention of the phonograph in and the first commercial digital recordings in the early s, arguably the most important milestone in the history of sound recording was the introduction of what was then called electrical recording, in which a microphone was used to convert the sound into an electrical signal that was amplified and used to actuate the recording stylus.
This innovation eliminated the "horn sound" resonances characteristic of the acoustical process, produced clearer and more full-bodied recordings by greatly extending the useful range of audio frequencies, and allowed previously unrecordable distant and feeble sounds to be captured.
Sound recording began as a purely mechanical process. Except for a few crude telephone-based recording devices with no means of amplification, such as the Telegraphone it remained so until the s when several radio-related developments in electronics converged to revolutionize the recording process.
These included improved microphones and auxiliary devices such as electronic filters, all dependent on electronic amplification to be of practical use in recording. InLee De Forest invented the Audion triode vacuum tube, an electronic valve that could amplify weak electrical signals.The development of analog sound recording in the nineteenth century and its widespread use throughout the twentieth century had a huge impact on the development of music.
Before analog sound recording was invented, most music was listened to by hearing a live performance, or .
Carnegie Speaks: A Recording of the Gospel of Wealth. In his essay “Wealth,” published in the North American Review in , industrialist Andrew Carnegie argued that individual capitalists were duty bound to play a broader cultural and social role and thus improve the world. Carnegie’s essay later became famous under the title “The Gospel of Wealth,” and in , at age seventy.
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.”. Audio recording and sound systems for churches have become increasingly important and sophisticated in recent years. With the explosion of new audiovisual technology, churches now have the ability to record and broadcast their message, music, and services to the entire world via the internet with ease.
The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies — can be roughly divided into four main periods: The third wave of development in audio recording began in The AES Historical Committee is an international forum open to all who wish to investigate and learn about the achievements of those pioneers whose innovative ideas and inventions have contributed to audio's rich past.
Dedicated to the preservation of over a century of audio history, the Committee is developing a broad-based history of audio engineering and the audio industry.
