*I'm saying we, since I would need to work with an expert. I am not only totally blind (who knows if this would be accessible), but I know nothing about this sort of thing.*
To make a very long story short, I am aware that there is severe frequency loss in acoustic recordings. That is why they sound so tinny, even when compared to the earliest electrics. Some voices are affected more than others, but even the ones with the best recordings still experience some of it. With the advances in technology at our disposal in 2025, however, I am wondering if it would be possible to attempt to restore some of those frequencies. Ideally, it might sound like something from the 1940's, but I doubt that is possible, at least with the earlier records, so at least the 1920's or 1930's would be great.
The thing is, I don't know exactly what is lost. So my idea is to record a modern singer (with at least a somewhat similar voice to the original) on period equipment and digitally symultaneously. In this way, we would have the live singer, plus two very different recordings. We could then compare the live, electric, and acoustic versions with a device or software that measures frequencies. Once we have determined what is lost, we could then try to restore the actual records in question.
If we were doing this with a cylinder machine, it would be very easy. Not only can one literally still record at the Edison Museum, but there are people today who record in wax with both real machines and reproductions, including commercially! However, the first singer whom I have in mind for this, Francesco Tamagno, recorded on disks, which complicates everything. I was very familiar with cylinder recording prior to designing this project, though I had never done it myself, but I knew absolutely nothing about 78s. Then, I learned.

As I was saying, it is beyond complicated! Even if we took a chance and recorded the wax master and then used it for playback, skipping the step of actually making a shellac record, there is still the issue of finding recording equipment from Tamagno's time, which is ridiculously rare and doubtlessly too expensive for most people to consider buying. You might ask why we couldn't just use a cylinder machine, since they were certainly around in 1903. The problem is that their frequency loss was different from shellac records, so it would ruin the experiment if the difference was significant. Is it? Can anyone tell me? Do we even need to make a modern recording, or is technology good enough that we can simply add in the frequences from previous knowledge? If this can be perfected, or at least made feasible, there are hundreds of singers whose voices can finally be let out of the can, at least a little, and made to sound more life-like! Many of these didn't live to see electric recordings. I'm sure everyone would jump on this if I said Enrico Caruso was on the list, for example. But he, too, recorded on disks. I wonder if we can skip the recording experiment and use a singer, such as Tito Schipa (my personal favourite), whose recordings span both the acoustic and electric eras, from 1913 to 1964, as a control and gauge the frequency loss that way. If we wanted someone who recorded earlier, we could try someone like Alessandro Bonci or Mattia Battistini, but both only made it to the 1920's.

Three friends an I are going to see Chappel Roan later this week in Queens. I like her pink pony club, and have been making a variety of pink ponies lately.
I decided to make some tiny pink "pony"s that the four of us could wear as necklaces to the concert. They also could be clipped onto hats. I got the tiniest 6mm blue phosphor glass I could get my hands on and filled them to just 8 torr neon (normally 18torr at this size) so they are nice an conductive an the battery lasts longer. Pure neon fill- so I can fix em if they break.
I do have to double check the rules of forest hills. I guess I could lie an say they are LEDs :). One of my friends requested a heart tiara (I think the tour has hearts in its theme) so I made two lil ones filled for battery life :).
I sure hope we can dance with the neon as a pink pony club :)

phosphor coated glass pony on the pattern before attaching the last electrode. You can see the tube I was using as a handle cut off right next to it
ruby hearts next to a now paint dipped ruby WIIFM crackle tube and a pony that I fixed (I dropped it when I got it home). Blue tubs also on the agiing table
four lit miniature glass "pony"s on the agiing table
one single neon mini pony being driven by a DC input transformer. The DC power supply driving it is only needing .78 amps at 12 volts.

Amid rising #electric #bills, states are under pressure to insulate regular household & business ratepayers from the costs of feeding #BigTech’s #energy hungry #DataCenters.
It’s not clear that any state has a solution & the actual effect of data centers on #electricity bills is difficult to pin down. Some critics question whether states have the spine to take a hard line against #tech behemoths like #Microsoft, #Google, #Amazon & #Meta.
