Also for the record.......

Western Electric- who built 2 different models, Victor, and just about
anyone who could understand basic electronics built turntables that
would play 78 RPM discs to accompany silent films. Many theatres kept
one of the vitaphone turntables long after the process had fallen from
favor just to be able to play these 16 and 12 inch 33 1/3 rpm special
purpose records.   

The 78 rpm turntable set was called a non-sync and had it's own motors.
The Vitaphone based units would only run at 33 1/3 rpm. No matter how
fast the projectionist had the speed controller advanced. 

I own a pair of the Western Electric units and have seen the Victor and
several independently made units which got the job done, no matter how
they looked.

Just for the record, the tune's from 1932, well past the silent film
era. 
I think these records were for intermission use, probably to plug songs 
featured in the show.  My guess is that they were made at 33 rpm because

it's the speed players in projection booths could handle.  With the same

performance on both sides, you could play it in the dark without needing

to know which side was which.

Nice restoration and reproduction too!

[ARSCLIST] Restoration of broken records...






There has recently been some discussions of repairing a broken or
cracked 
record.  Everyone seems to have their own pet solution to the problem of

making 
the record play again, some come close, but none provides a fully
restored 
result.

For some time, I have been intending to post an example of using CEDAR 
processes to restore a broken record and here it is.

This one is seriously cracked, but the process for a fully broken disc
is 
essentially the same... get it into a playable condition and use 
computerized 
de-click and de-thump processes.

The source disc is a 10" American Record Corporation No. E 587 issued 
around
1930, for theater use.

Love, You Funny Thing! - Imperial Dance Orchestra

See label photo here:  http://www.audio-restoration.com/CIMG4743t.jpg

It was recorded at 33-1/3 rpm, transcription style inside start, with
the 
same
tune on each side.  The disc has a large 1/2 moon crack in it with one
end
still intact, but hold it up to light and you can see light through the
separated end!

Reasoning was, they were played by the projectionist to synchronize with
showing of a silent film.  Being shellac discs, and with the heavy
weight 
of
the pickups and steel needles, the discs wore out very fast.  As one
side
became noisy, the projectionist would order a new disc and start using
the
remaining good side.

One pass used CEDAR de-clickle to remove the leading impulse clicks.
The remaining thumps were removed using CEDAR de-thump installed on
SADiE 
5
workstation.

The two audio files can be lined up to see there is no timeline 
discontinuity
as there would otherwise be with conventional physical editing.

Here is the de-clicked file prior to de-thump being done:-
