  • finally a video that explains it. i totally understand now.

  • To record mono is to take the L/R hots, pair them together along with pairing the grounds. then feed the paired lines into a "Y" for separate L/R inputs of the recording device. This eliminates the "stereo" effect of the mono playback - like actually listening to a mono sound through paired speakers.

  • IF I REMEMBER CORRECTLY THE FIRST 33 LPs (smaller ones)

    & THE SINGLE 45s WERE FIRST PUT ON THE MARKET IN 1948.

    & THEY WERE VINYL ONES. 78rpm RECORDS HAD SHELLAC

    AS AN OUTER COATING.

  • Cool

  • Edison records are a material more like roofing tar than baker-lite. The puck is sawdust coated with a tar like material. Vinyl records did not exist until the late 50'S. As LouiePlaysDrums stated, 78's are shellac. Not vinyl. If you want details just ask.

  • @dave631bnetzero ... in 1946 RCA released, on the RED SEAL label, their first red vinyl 78's .. they were called "Red Seal Deluxe" the vinyl was called "vinylite". Columbia, in 1948, introduced the vinyl LP. RCA, in 1950, introduced the '45rpm' to go against Columbia's LP, but RCA conceded in 1951 to produce the LP

  • @DSM1G90 Very nice records! I have only four sets on the "Red Seal Deluxe" label. 12 Inch 78's.  Rare i think today. I have a lot of Red Seal clear wax 45 box sets. I like to collect these. Thanks so much for the info. I did not know the history. I still play them from time to time. Still playing after almost 70 years. I bet my MP3 player will be long gone in a lot less time. Nice to have these around.

  • that recording of Edison speaking into the phonograph was made in 1929 for a newsreel

  • Comment removed

  • Infelizmente temos erros aqui . Os discos mostrados não são de bakelite e nem de vinil e sim de shellac, uma pasta de diversos componentes...

    The records are not vinyl or bakelite... are shellac made !

    Please made the corrections .

  • RCA created what they called "Program Transcriptions" in late 1931; 33 1/3 rpm was already established as a speed for 16 inch radio transcriptions, and RCA decided to market a 10 inch "33" record that played about 10 minutes per side. But one had to buy an expensive Victrola radio/phonograph combination to play them, and the heavy tone arm used to play "78's" really weren't suited for those records. Their "long play" disc was quietly discontinued by early 1933, primarily due to the Depression.

  • It is true that the Edison Diamond Disc was made of Bakelite, but when that format started in 1912, the surface was celluloid. That was actually a better material, but it had a tendency to de-laminate from the wood-flour core. And so the switch was made to Bakelite.

  • @riqzster Yes, the very, very first DD's had a celluloid surface when introduced in 1913 but they immediately abandoned that. The material is not Bakelite but the chemically close Condensite, a different brand that was owned by the Condensite Co. . The core is different and contains a great portion of wood flour which quickly soaks water and expands, thus causing the surface to detach or split. Therefore, unlike with shellac 78's you should only wipe them with isopropyl alcohol, not water.

  • Whats the song at the end?

  • @wasp9 That's "The Charleston", which came out in 1925.

  • From what I know, Edison invented the wax cylinder recorder around 1877, the record was invented by Emile Berliner in 1895, it was later adapted by RCA and sold worldwide, the material of the first discs were either rubber or shellac. Shellac soon became standard. Later, during World War II, vinyl was used to make 78s, and by 1948, Columbia invented the LP (Long Play) record, at the same time RCA was making smaller vinyl discs that played at 45 RPM.

  • @cartoonfan1920s Edison's original phonograph utilized tinfoil, not wax. And a record is a record, no matter if it is a cylinder or a disk -- just like tape is tape, no matter if it is cassette format or open reel.

  • how could a needle modulate sound by vibration of sound?

  • The record shown at 1:28 is not vinyl. It's a shellac 78RPM record. Records did not start coming out on vinyl until the mid-1940s.

  • Hmm, no-one mentioned Shellack in there!

  • In recent discovery Edison is not the first to record his voice. But some dude over in Paris. He just never knew how to play back his piece.

  • @GrEEnXThirTEENs

    Yes, the 'dude' was Edouard Leon Scott de Martinville, on his invention the Phonautograph. Some of his phonautograms from 1860 have now been rendered audible by modern digital techniques, and can be heard on YT.

  • @saltburner2

    That's the dude! Thanks

  • @GrEEnXThirTEENs Edison was not the first to discover many of the inventions he was credited with...The only reason we know his name and not Tesla's is because J.P. Morgan funded Edison over Tesla when he found out that Tesla wanted electricity to be free for everyone.

  • @GrEEnXThirTEENs Well, a lot of good that did. Edison's inventions actually worked. You Tesla freaks give me a pain. I think the truth is that you just resent American innovation.

  • @M1GARRAND1

    I'm not a Tesla freak and never stated I am. Plus, I don't resent American innovations either. I was doing a research project on audio recordings and found information on so much. During the time of this paper they discovered Edouard Leon Scott de Martinville work piece. I just like to get my facts straight, understand where they came from and give credit to that person. So, do what inventors do before anything-- "Think before acting."

  • @M1GARRAND1

    Raged at the wrong post there, bucko. I think you owe Mr. Green an apology.

  • @Karlfalcon

    Ha ha. yes you are right. but try to understand MiGARRAND1, there is an abundance of weirdo Tsla people who believe all the BS he wrote in his autobiography while he was jealous, legally demented, and old. They post crazy comments all over the place and it is tiring.

  • Edison was a poor speaker, just as Disney was a bad cartoonist. They had others record for them.

  • That was NOT the first edison recording. That was from an interveiw of Edison around 1929. Look up Edisons "talking clock" experiments.

  • @Richardddoobies That's correct. Edison was merely recalling the 1877 event at a 50th anniversary observance that occurred in 1927.

  • Have You the "Chicken Pie" Song by Lew Dockstatter and His Minstruals?
