The powers that be have always waffled on that. My feeling has always been sell chips so empower more people to use them. The current situation is in flux to say the least. I don't think this aspect will be a problem the SHARK can run Linux the rest is essentially open source.

I had an old Grado cart the was Left neg to ground. I think. Only a 50% chance I'm wrong.
Yes finally, I had to jump through hoops to get a license for an MIT grad student years ago. They finally saw the light.
A digital noise suppressor, it is possible ?
Perhaps many remember the suppressor DBX clicks and pops.
Of course, in those days there was no digital technology and analog media of the time, served its function.
Although the sound was overshadowed by a veil, quite audible for trained ears, I think it was better to listen in this way and not the torture hear a violin or other instruments altered by one or more high-frequency clicks or pops
With the advent of bits, and by programs like Cool Edit Pro or similar, any of us can achieve excellent results with vinyls, eliminating all those obnoxious noises. Of course, keep the frequency spectrum and dynamic range is the fundamental premise, but with some practice it becomes quite easy.
Question :
Why in the digital environment it is not manufactured to DBX or others similar device with a specific program to remove these noises? We know that a scratch on the vinyl groove produces a snap that has its own characteristics!
We see it on the screen when we operate the program clearly, but work to go all the musical theme eliminating one of these peaks is very cumbersome and ended up leaving her job ..
Why not do it in a pre-programmed chip that works in real time?
It is a very silly idea? What would be the problem or hurdle to overcome ?
Something that eliminates noise vinyls digitally and in real time.
Sorry for my English, I hope the idea is understood...

Here is, I think this should be very effective !!!
CEDAR, noise reduction, hiss reduction, click reduction, sound restoration
Very thanks , Academia50

Vinyl click and pop removal
For sure Scott, when you are processing a master, if you concentrate on one aspect such as a click too long, you end up with a bias toward too much reduction and the resultant fidelity suffers. I have no experience with newer techniques, and am really interested in hearing how well they work
I do not use Audition nor Cool Edit, I usually work in Sound Forge these days so I cannot audition ClickFix, but would love to see your plots of it's action!
I'll tell you where my mind is right now: due to my work history I am really over the task of taking a s#!tload of time transferring vinyl, but would love to have a more automated way which didn't ruin the fidelity. Acquiring the metadata and tracking in addition to painstakingly reducing noise pretty much totally kills the joy for me, so I end up just listening to a lot of vinyl. I took a look at that Sugar Cube box (thanks for the link, billshurv!) and if it worked half as well as it seemed to and claims to, I'd buy it because it automates a lot of that process. After having said that I now have to confess that most of my vinyl collection will not show up in their fingerprint database, although probably some of the more popular stuff should.
I've been using the Auralic Vega D>A for a year now and I am really happy with the sonic performance, so if I can just get vinyl into 96/192K/24 bit (storage is cheap) without massive massaging of the resulting files I'll be happy.
Cheers,

CEDAR the link I attached that you can hear the result. I did not finish convincing, I still hear clicks after the process at a fairly high level.
Perhaps at my age I'm still a golden ears ...
Resurrect your old recordings | Audio Restoration | Brian Davies is a low cost option with some samples to listen to. I do think comparision of different SW tools is a useful part of this endeavour. Sadly clickfix requires a soul extraction by adobe CC these days.
For some reason I speak direct drive circuits passably, but most of the rest is beyond me. I found and have been using this guy's flat balanced MM pre: Pro Audio Design Forum • View topic - Phono Transfer System.
It's small enough I can get away with ~6" of cable from the arm and tuck it behind the 'table.
From there I use a Tascam DA-3000 for AD and to record, and have an OpenDRC-DI (miniSHARC in a box) hanging off the SPDIF output of the Tascam for EQ. No complaints.

Thanks for the repost! For sure the reconstruction in the first link is pretty amazing on a sine wave. I'd love to see what it does with source a bit more complex. If it is that good I may have to invest in Cool Edit (I despise Adobe, even though I use InDesign/Acrobat Pro/Photoshop all the time).
Correlation between channels is another technique which can yield good results, and I think the Packburn employed that.
Regarding CEDAR, I'm sure they have updated their algorithms since I used it, but as I remember in general it, like many other digital fix tools leaves a dull thud after taking the higher-frequency components out. That agrees with Scott's comment regarding spectral-based approaches. I do, however, have a different experience with ultrasonic triggered reduction than that of baseband derived reduction.
Great topic!

One great value of phono digital de-empasis eq is in processing 78rpm recordings.
Recording houses ran differing emphasis eq curves - COMPUTER EQUALIZATION OF 78s.

The status of CoolEdit 2000 is in limbo, it's not clear anymore that anyone cares if you download it from a piracy site. I can't get my copy to record from a USB device and really get 24 bits anymore anyway. A few folks got surprised by this, examination of the actual data showed 8 trailing zeros. Same with Audacity in many(all?) cases for different reasons. None of the devices or the software reports any errors.
