What were big-band era recordings recorded onto?
It's my understanding that wax-cylinders were one-offs. If you wanted
100 copies you had to have 100 machines running, or record 10 times with 10 machines etc. What about the recording formats that came later? What was the master? |

What about the recording formats that came later? What was the master? Well, for discs originally the master was cut onto a soft metallic wax, which was then plated and used as a stamper. This graduated to a nitrocellulose lacquer which was then plated and pressed. The lacquer could be played directly once or twice if you were very careful so you could tell what you had recorded without waiting a week to get your metal back from the plant. And then in 1949 Ampex came out with a commercial tape machine and then everything changed. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

So basically it was a "direct to disk" system. Did they generally only make one per recording? Seems like it would be dicey to depend on a single stamping to make however many records you were going to press. So when you hear these Swing Era compilations, surely they're not taking them off the original master? I would assume they must have been transferred to tape long ago and then at some point digitized, particularly as noise removal and enhancement technology has improved? |

Were there any experiments with stereo prior to tape?

Seems like it would be dicey to depend on a single stamping to make however many records you were going to press. You can do two-step process... plate the disc, make a negative image, plate that and make a positive mother, then make multiple stampers off the mother.

They're almost always done off of pressings, although occasionally you will find recordings where the original lacquers exist. Normally the lacquer is destroyed in the process of making the pressing. Sometimes you will find metalwork in the archives, and the metal can be played directly with special apparatus or you can make clean pressings off of them. Many of the recordings in the forties would be pressed on ordinary shellac for consumer use, with all of the filler that normally goes into shellac. However, they would make pressings on unplasticized vinyl for radio station use; those DJ pressings couldn't be played on an acoustic phonograph but they were much, much quieter than the shellac. There were also some consumer discs and V-discs made on filled unplasticized vinyl. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

A concert was transmitted via telephones and holding one telephone connected to one microphone and another, connected to another, allowed listening to the transmission in glorious A-B stereo. And then there was Blumlein in UK in the 1930'ties and in the US I think Disney was the forerunner, but the local people over there know that tale better than I. Suggested literatu Blumleins patents.

Both Bell Labs and EMI experimented with stereo recording. The latter even patented a stereo cutter head in the 30s. You need to do some research on your own. Start with "From Tinfoil to Stereo", and search the Web. |

It features the Glenn Miller Band. Corny movie, but an interesting look into how things were done then. It is available on DVD. John Hardy |

There is a movie from 1942 entitled "Orchestra Wives".
Also "Sun Valley Serenade". Both films were recorded on RCA's 7-track optical recorder (which was also used for "Fantasia"). The stems survived, and one can hear these films with an ersatz-stereo soundtrack. |

High-frequency AC bias seems to have been invented several times, apparently independently. In 1921 Wendell Carlson & Glenn Carpenter of the US Naval Research laboratories applied for a patent on it. In 1939 Marvin Camras of the Armour Research Foundation in Chicago rediscovered the technique. Around the same time Kenzo Nagai in Japan also rediscovered the technique, but I don't have further details. Finally, in 1940 Walter Weber & Hans Joachim von Braunmuhl, in Germany, rediscovered it and applied it to the Magnetophone. After World War II ended an American named Jack Mullin, who was in the Signal Corps, liberated a couple of Magnetophones with DC bias and brought them back to the States, where he refitted them with AC bias.

Yes. But Ampex actually made a commercial product that you could buy over the counter. Within two years, every studio and every radio station in the country had one and the world had changed. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

But it was the opening scenes of Orchestra Wives that caught my attention the first time I saw it many years ago. Sounded great, even on small TV speakers. I wasn't sure which movie had those scenes, so I put both of them on my "Secret Santa" list and received both of them about three years ago. John Hardy |
