That's a classic Mark! Especially to those of us who grew up with Alfred Hitchcock.
Your record sounds super, it's in great shape for a popular (i.e. often played) record
from 1935.
Thanks for sharing.

I don’t think it was played much. There were a few real nasty pops, Audacity to the rescue! Mixdown to mono also cancelled some scratchiness.

It still has a fair amount of bass, I can’t imagine it being too far off.

I will guess it likely has too much bass boost because they had more groove width in those old 78 pressings. There is no such thing as electronic equalization in those old steel needle, mechanical playback machines.

By 1935 there was an exodus from acoustic phonos, and the shellac formulation had less abrasives. Still used steel needles, but with crystal transducers instead of mica diaphragms. Far less tracking pressure, but still barbaric by today’s standards. A record was a record- and that’s it!

Audacity used to have EQ curves built in- and thanks for that rabbit hole! I remember seeing curves for Columbia, Victor, and even acoustic, there was even an “inverse RIAA” curve. They’re gone now. For shits ‘n’ giggles, I went back to the iMac and opened the file hoping to nullify RIAA and apply the Victor EQ, but the curves aren’t there anymore.

I’d need a db/octave graph to recreate the Victor curve, but that’s a hole I don’t feel like crawling into right now.

Yes- the fixed pitch grooves are quite dynamic! Electronic tube amplification in recording began about 15 years before home phonos had tube amps, whether EQ was applied is a mystery to me.

Correct me if I’m wrong in any of this- INCREASE MY KNOWLEDGE!

EDIT: IIRC, the “V.E.” in the runout of Victor records denotes electronic recording.

You have opened up a good conversation Mark. What did happen before standardization...? The VHS vs Betamax wars for the groove.

Columbia, Victor, and Brunswick all calibrated their recording characteristics to their own phonos, but with indifference to acoustic phonos because they all sounded like shit no matter what they did. Other manufacturers (Perfect, Okeh, etc.) were loose in their standards, but eventually adopted the guidelines of the companies who bought them out. The differences weren’t all that great, but did serve to show a need for a standard- that’s when RIAA pounded the gavel, playback EQ standards were then adopted by the various manufacturers.

The records were playable on any (lateral tracking) phono, the differences weren’t always noticeable, but there nonetheless. There was still a preponderance of acoustic phonos out in the wild- nobody knew the difference…

A td-124 with a SME 3009, Hot damn!
 
With 78 rpm surface speed, I think there are fewer frequency issues. The limitations are/were in the hardware (and it was HARDware.

Just see the improvement 45 rpm makes over 33.3… 78 is to 45 as 45 is to 33.3…

Imagine how good virgin vinyl could sound at 78 rpm with the latest technology and decades of experience…

Funny that you should mention the difference in formats…
Video to come…

Consider the difference between 7 1/2ips, 3 3/4ips, and 1 7/8ips on an open reel deck…
