If I'm not mistaken, the last post on this NG, was waay back in 5/16/2025???

Are Usenet Newsgroups FINALLY dying off?? FOR GOOD?????

SAD TIMES!!!

I check it but i haven't done much original audio work recently and
there hasn't been anything here to reply to.

I could start a thread on an analogue declicking computer for 78s,
which I am currently designing, but the number of participants would
probably be very limited.

Well, maybe about 4-5 years ago, this NG was still quite active,
but things looks quite different today.

This is quite a loss, since I've learned TONS from the
participants, over the years!

So this is quite sad, since there is NO replacement for these censor-resistant Usenet Newsgroups!

You might be surprised. Is it working? How does
its performance compare to digital solutions.

The performance on old and worn 78s is superior to any of the digital
methods I have heard so far, although it needs skilled operation to
achieve this. It also works on a par with CEDAR on badly worn mono
microgroove records. It is less effective than CEDAR on good-condition
LPs and 45 rpm singles and will not work on stereo recordings at all.
As my original brief was to de-click and de-crackle 78s, I feel it has
been a success from my particular point of view.

The prototype, which was built to test the basic principle, has been
working in commercial use for over 30 years. A second version was
built for another commercial studio specialising in the re-issue of
historic opera and that worked successfully for over 10 years until the proprietor died and the firm closed down.

One of the biggest improvements, which was made very early on, was to
split the sound into two frequency bands and operate on them separately
before recombining them. In particular this reduced the audibility of
the intermodulation cause by gaps in the wanted audio. I have always
wanted to split the spectrum into octave bands so that any
intermodulation and distortion by-products fall outside the band filter
for each channel. In theory this should give much better results in
unskilled hands. Currently I am building a new machine to test out the
theory.

If you want to know more detail, I am happy to give it but it does
require some background knowledge of analogue electronics.

I continue to drop in now and then, I'm happy to find audio friends who do so as well. Here's a conundrum in quest of ideas:
Like many, I have a decades-old accumulation of "Audio Stuff". Mics, processors, cables, connectors, one-off gadgets etc. eBay, done well, takes more time than it should. I guess I might be seeking someone who knows audio gear and wouldn't mind splitting the rewards of unloading some interesting relics. I wont need help with the NOS RCA 77DX. Words like T4B, QGP and KEPEX are familiar. All the 'stuff' is analog, mostly useful and generally of meaningful quality. Perhaps you've been looking for something I might have, just ask. If you know of a person or place that can help, please let me know.

If you can keep it in good condition and hang on to it for a few years,
it will become 'cult' and then you can sell it for a fortune.

Thanks, Liz. In a sense I've already done that. What could be more 'cult' than a NOS UREI T4B? Has anyone here used a KEPEX to introduce a "very different, yet pleasing" 'snare' sound?

I'm pleased to report that the MkIII version which I have been working
on recently has now worked for the first time. The results are very
promising and it is extremely easy to operate.

Unfortunately, in trying to track down a common-earth hum problem, I accidentally blew up one of the power supply regulators and I didn't
have a spare. A new one is on order, so I hope to resume testing in a
few days.

The basic principle is to split the sound spectrum into ten bands, each
about an octave wide. In each band a click or crackle is identified by comparing the vertical and horizontal vectors of the stylus movement -
if there is more than a certain proportion of vertical movement, a
switch opens and momentarily disconnects the signal. The band is then
filtered again, so that the harmonics due to switch clicks are removed
and damped resonance in the filter covers any short gaps in the sound.
All ten bands are then recombined to restore the original spectrum.

My previous attempt (the MkII) used inductors in the resonant circuits
and became so cumbersome and difficult to align that I abandoned it.
The latest version uses 'state-variable' filters based on op-amps and a
cascade filter configuration that makes the centre frequiencies far less critical and allows the use of ordinarly 5% tolerance components. The
overall pass band is within 2 dB of flat from 20 c/s to 20 Kc/s and the
ripple due to filter overlap is less than 0.5 dB.
