Looking for a declicker

[d.healey]

Can anyone recommend an open source declicker plugin (preferably LV2 or VST3) or commandline tool? I'm aware of the tool in Audacity.

Thanks.

You may want to try ocenaudio. Zoom in on the spot where you hear the click. (You'll probably be able to see a "wonky" shape to the waveform there). Zoom in tight. While holding the left mouse button down, drag the mouse across that discontinuity in the wave to select it. Then issue the "Effects -> Smooth" menu command. Listen to the result, and if still not fixed, try selecting a little bit more of the wave, and try "Smooth" again.

Thanks for the suggestion but I want either an open source commandline tool or plugin. I'm aware of a multitude of proprietary GUI apps that can do the job.

It's free but it's not open source,
I don't know if it meets your requirements, but you could take a look at it..
VST,VST3,LV2..

Ah ok.

A lot of tools won't retain the looping information, or won't adjust the loop points if the length of the waveform changes. None of the ocenaudio functions lose, or fail to adjust, the looping. That's one big reason why I use it instead of other linux tools. If you find a tool that does the waveform smoothing, check to see if it also retains your looping.

That's fine, I need it for fixing clicks in individual samples before any looping has been done.

I'm happy to pay for an open source tool, I'm not happy to use a proprietary tool no matter the price.

I wonder if the guy who writes ocenaudio could be convinced to sell the rights to the code. It's really the best wave editing software on linux.

I asked about open sourcing it on their Facebook page years ago, never got a response

Their facebook page doesn't seem to be used much. You may have better luck using the contact form on the ocenaudio website:

https://www.ocenaudio.com/feedback

There's also the following text on the facebook:

O ocenaudio é um editor de audio multiplataforma, fácil de usar, rápido e funcional.

That's italian I think. Maybe the guy doing the facebook page is italian, in which case there's a good chance he doesn't speak english?

Ocenaudio was developed at a university in Brazil, so I guess that would be Portuguese.

I used Ocenaudio for a bit. It has a nice interface but ultimately didn't have any features I needed which weren't available in the open source Audacity. Audacity has draw tool which can edit waves to remove clicks.

For removing masses of clicks found in recordings of old records, I go to Windows and use Izotope Rx. It's restoration features are really good but not cheap and definitely not open source.

AFAIR gramofile wich is a tool to digitalize vinyl records has a declicker feature.

I don't see that feature mentioned on the website. Does it have a CLI?

This exists on GitHub, though I haven't tried it yet:

Either you try to compile it for Linux or you run the windows binaries with yabridge.
