I am a group newbie and a self-confessed ignoramus.
I have a small collection of 78 rpm records bought second hand decades ago that I am trying to share. I have bought an ion usb turntable (all I can afford). and am using Audacity. http://homepage.ntlworld.com/davidfcox/html/78s.html Any references to on-line how-to guides appreciated. I have a mission to save old 78 recordings, particularly old gospel, skiffle, blues, jazz, big band for which more modern media does not seem readily availiable. If possible I would like to move towards collecting multiple wav recordings together with a view to "stacking" them. That is intelligently adding the signals together to improve the S/N ratio. Stacking is a technique that was (is?) used in oil exploration, where the inputs from multiple geophones located a distance apart are added together to improve S/N ratio. David F Cox |

Not the same thing for a turntable, since the noise source (The LP) is plagued with random noise, but rather the noise is mechanical and highly repeatable in nature. If you want to improve the noise from old recordings, there are computer programs that can be highly effective at noise reduction. |

The problem with 78s is that there was basically a period of more than fifty years during which they were made... and the technology over those fifty years changed dramatically. This means things like equalization curves and stylus sizes are dramatically different between a disc cut in 1905 and one cut in 1950. I think you will find the need to have a wide variety of stylus sizes will kill your budget more than the table itself. I think the ARSC would be a good first place to look as far as basic information on disc transcription. I have a mission to save old 78 recordings, particularly old gospel, skiffle, blues, jazz, big band for which more modern media does not seem readily availiable. Note that a lot of those recordings may still be under copyright, even if they have basically dropped off the face of the earth. If possible I would like to move towards collecting multiple wav recordings together with a view to "stacking" them. That is intelligently adding the signals together to improve the S/N ratio. I think you'll be surprised at how little good this does, because the noise correlates in most cases. Now, stacking multiple pressings of the same recording can be of help. Most of the surface noise on the 78 is deliberate; it's the result of fillers added to the material to keep steel needles sharp. And it's the same every time you play it, because the particles don't move around. This is why DJ pressings, vinylite pressings, and V-discs are so much more valuable... because they are designed to be played with jeweled styli they are not filled (or only lightly filled) and consequently much quieter. The key to good playback of 78s is to get the right size stylus so that you get the distortion as low as possible, and then to get the equalization right. In the case of electric discs the equalization curves can often be looked up; many manufacturers would use the same curves across a number of matrices. In the case of acoustic discs it's often more a matter of taste than anything else. Noise is easy to deal with these days with processing, but distortion is not. --scott -- "C'est un Nagra.

If you want to improve the noise from old recordings, there are computer programs that can be highly effective at noise reduction. I was thereabouts at the dawn of such programs. As a general point of information the noise in seismic recordings is also highly mechanical and repeatable. Most of the recordings I was dealing with contained propellor noise from the ships engines. The other main source of noise was multiple echos. This occurs between rock layers, but is most severe as the signal reflected from the sea bed and back from the sea surface. In the worst case the original signal looked like a sine wave with noise to signal ratios of 80dB (as I recall). I go back to TIAC computers with 4K of 32 bit memory that sorted that problem out. Another question that bothered my over-active brain was could the fact that there is crosstalk between the current groove and the previous and the next be used, in extremely desperate cases, to fill in lost signal? It is another form of distortion, a much reduced version of the seismic echo problems. David F. Cox |

No, it's much more of an issue with LPs than with 78s, and for the most part it's only lower frequency stuff that leaks. Most 78s were cut constant pitch. --scott -- "C'est un Nagra.

I have two copies of "Basin Street Blues" by Louis Armstrong on 78 to play with. (Up until the time I acquired them I had rather dismissed him as a being an entertainer rather than a musician. It is a recording that inspired me, and one I have not heard anywhere else, though I am sure it must be on many collections.) I have just started perusing the Audacity manual. It looks like the super geeky stuff has been done and is open source. Besides that there is apparently a Lisp like programming language that works with Audacity. It is just possible that the required tools are in reach. ------ Thanks to all that have so far replied, I am learning lots. David F. Cox |

Sadly Peter has died, but he did get as far as making one recording of two synchronised copied of "The Ying-Tong" song by The Goons. The reason he chose that was because an LP version existed which had been cut from direct from tape (not dubbed from the 78s) which could be used for comparison purposes. When the synch of the two 78s drifted slightly, you could hear the hiss from the master tape going in and out of phase. At the time, the only easily-available phase synchronising system was one made for de-skewing stereo channels in a broadcasting cartridge player. Peter had the idea of minimising the initial phase error by playing the copies simultaneously on a 'cake stand' stack of turntables with identical arms, which he proposed fitting to a Scully recording lathe. I believe some written records were made of Peter's experiments and these should be in the posession of the British Library National Sound Archive. You could contact them and ask. One problem to watch out for is cyclical wow which can result not only once per rev from a badly-centred disc, but twice per rev if it has been stored badly or was pressed from a stretched stamper. Another problem arises if the two copies are not from the same metalwork. It is not unusual to find two different versions af a best-sellling record where a re-cut was necessary after the metalwork got damaged - you would have a hell of a job synchronising those. I have two copies of "Basin Street Blues" by Louis Armstrong on 78 to play with. (Up until the time I acquired them I had rather dismissed him as a being an entertainer rather than a musician. It is a recording that inspired me, and one I have not heard anywhere else, though I am sure it must be on many collections.) The simpest way of de-crackling those is to pay to have a vinyl pressing made from the metals; someone on the left of the Herring Pond can probably tell you who owns them. The cake-stand method is only really viable for the situation where the metalwork has been lost but many pressings still exist. -- ~ Adrian Tuddenham ~ (Remove the ".invalid"s and add ".co.uk" to reply) www.poppyrecords.co.uk |

m... I have a mission to save old 78 recordings, particularly old gospel, skiffle, blues, jazz, big band for which more modern media does not seem readily availiable. May I refer you to the following labels: Document, Yazoo. Lots of blues and gospel on there, not so much skiffle, jazz or big band. There are, however, equivalent labels for those styles. If possible I would like to move towards collecting multiple wav recordings together with a view to "stacking" them. That is intelligently adding the signals together to improve the S/N ratio. Stacking is a technique that was (is?) used in oil exploration, where the inputs from multiple geophones located a distance apart are added together to improve S/N ratio. It may work in oil exploration, but it won't on 78s. The S/N is limited by the discs themselves, not the technique used to play them. Peace, Paul |

I have just renewed my interest in this project. When I looked at the net for info about artists and tracks years ago I found practically nothing about many of them.

One web site says no recordings were made at that time. This, naturally, is one of the records I cannot now find. The other is Louis Armstrong singing "I double dare you".

It appears that the world has moved on considerably since my last look at the situation a few years ago. Most of the tracks I most wanted to share have now been uploaded by others. The innovations I wanted to explore have been explored. This is all good. The one record I most wanted to upload I cannot find, and I have not so far found it on the Net. To add to my misery I have found one site that tells me that no such recording exists. Thanks to all that have responded - I have learned a lot in a very short space of time. David F. Cox |

Peace, Paul Apologies ( :-) Things have so moved on since I did my web searches before our last house move. Now there are Jazz sites with massive catalogs of tracks that can be heard for free. Amongst them was the track I was talking about. I evidently remembered the date wrong. It was 1923 not 1918. I also learned: " one of Ellington's most grandly sensual works is his early blues piece "Creole Love Call." This 1927 classic was inspired by "Camp Meeting Blues," a 1923 recording by an earlier Crescent City trumpet monarch, King Oliver. When Ellington's version was released, Oliver tried unsuccessfully to sue the record label. " http://www.jazz-on-line.com/King_Oliver.htm It looks like I have been wasting this groups time, everything I wanted to do has already adequately been done. Back to working on my own songs. Probably too much of them has also already been done. ( :-) Thanks again David F. Cox |

Like everybody else I have music that does it for me. I have felt like electricity was running down my spine listening to live blues and jazz performances by the likes of Sonny Terry and Brownie McGhee and Ottilie Patterson and virtual unknowns in back street bars. I would like to share that music with those that have never heard it, pro bono.There are more and more online merchants doing a better job than I could at that with the American artists. There is actually quite a bit of British work that is worth a listen too, that is less well known. One of my main hobbies is Modern Jive dancing. I have put some samples of Ottilie online for DJ's to try and get her some play time at dances, once again pro bono. I think her early work, before her voice was damaged, is just about out of mechanical copyright. http://homepage.ntlworld.com/davidfc...l/ottilie.html I do have some self-interest, I am seeking permission from collaborators to get some of my own songs "out there".
