plugin / sw to de-artifact a wave

[EfreetiSultan]

for example, low bitrate mp3 fix, stem seperation fix, etc.
Where theres tons of artifacts and you want to clean it up a bit. I know ive seen something like this before many many years ago but i dont know which are good in this current day.

Im sure theres tons of AI stuff that can do it now.

Izotope rx is the one creating the artifacts is there a de artifact process there I'm not seeing?

I have spectralayers since I own cubase. What process there should I use to clean up artifacts? You seem to sit on information I don't have so please be a bit more specific

I've not tried Acon digital before, can you be more specific please?
Thanks alot!

Perhaps Unchirp by Zynaptiq?

Perhaps go easier on the settings? Try iterative processing as opposed to doing it in one shot.

good suggestion, i tried iterative processes but unfortunately the results was the same. the seperated vocal still had way too many artifacts to be usable

There is no such software because there is no algorithm that can recreate what has been lost. The best you can do is to fill the gaps with noise.

It's not been lost. It's all there. It's just tons of artifacts left behind when trying to separate the stems.

And also, you're kind of wrong, there are indeed such algorithms, that does try to add back in what has been lost. They have existed for a very long time. But that's not what I'm looking for right now, just something to clean up artifacts after stem separation.

Those artifacts are the result of filters punching holes in the spectrum. You need to fill them up to make the artifacts less audible. This can be done by adding filtered noise.

its a full mix tho. in this particular case im working on now, theres a constant 16th note hihat, theres open hihats, theres snares, kicks, bassline, some synths, some fx, and a vocal.
i need to add noise to this to get a better vocal extraction?

Maybe you didn't get the notification so I'll reply again to make sure. Cause sometimes I don't get any notification either. Can you tell me how to use these applications to reduce artifacts. Thanks

The noise is only for reducing the lateral inhibition (the ringing sound) caused by the destructive filtering. You need the vocals (or whatever) extracted first, then you use filters to punch holes into the noise, then you mix both together.

They all have several modules/algo's to clean up artifacts. Denoise, declip, declick, de-ess, deverb, and so on. They also all have preview functionality, so you can already decide beforehand which settings work best, to avoid most artifacts.

This unlike some others, which do everything automatically but give less control over the whole process. That might work well in many cases but when you have difficult tracks you're better off using the 3 that i mentioned.

Often it requires a lot of trial and error tho. There's no clear "how to" because every source needs a different approach. Or repeated processes, or even partial renders.

The Spectralayers version bundled with Cubase is only a "light" versions which contains only a few modules of the full version. It's also taken from the previous version of Spectralayers, which has been much improved since.
