'Bygones' special on the history of HMV.
I stumbled across this video today. A special edition of Anglia TV's "Bygones" programme from the 1980s. Features a few shots of early record and radiogram production, a scary looking auto-changer and some restoration of archive recordings. No editing software here!
https://www.youtube.com/watch?v=3CsIZed38Go It's just the first 25 minutes for HMV, but the other films are also interesting. Make yourself a cup of tea and enjoy. SR |

Loved the traditional click-removal technique for reissued 78s; impressive scissor accuracy.

Re: 'Bygones' special on the history of HMV.
Thank you Stuart, That HMV automatic record changer is great, or not. Its around 15 minutes in. I wonder if it has a built in waste bin?

Quote:
John RT Davies developed a system of blanking clicks by scraping oxide off the tape at exactly the peak of the click, and taught it to me. It worked well, although it could be laborious, but its cardinal virtue was that it left the timebase unchanged. When I went over to digital editing, I was forced to return to cut-and-shut techniques initially, but these could be made much less invasive by the ability to both see the click and match the waveform so that the edit did not bump - this meant that less material was lost. Eventually, CEDAR manual declick and dethump enabled disturbances to be removed so well that there is no sign of their having been there in the first place, and without losing wanted material. |

Re: 'Bygones' special on the history of HMV.
I remember using an Amiga with a primitive voice sampler and a machine code monitor (basically a memory editor) to try to clean up a noisy recording. It was a bit laborious, having to find the right place in memory and manually enter the hex codes for the new sample values, then adjust the screen to force a redraw; and limitations of RAM (all the samples, the sampler software and the memory editor had to squeeze into the machine's memory) and lack of a hard disk drive prevented me from doing a complete side of a 78 in one go.
But at least it proved the concept in my mind: working at the individual sample level, scratches could be edited out. Nowadays, Audacity already lets you redraw the waveform manually without resorting to external hackery. But it can also do it all for you :/
