What has happened here is that the signal has gone so far off the scale that it has appeared on the other side.
Actually that should never happen, and is partly due to your sound card handling the overload incorrectly.

For a good recording, you need to be able to be able to avoid clipping rather than try to correct it. Correcting bad recording is really a last resort which can sometimes work in removing small imperfections in an otherwise good recording.

If that is where the clipping occurs, you need to turn down the gain on that channel and use the level fader to bring the volume up to match the other inputs. If the level fader will not go high enough, then you need to turn down everything else.

Of course we still have to establish what exact value of Δ_y_ is required for something to be identified as a clip. This could be left a variable for the user to set himself while executing the plugin. A second requirement for an area to be identified as clipping (to prevent false positives) is that the y-value must remain in the negative until a sudden high slope is found, marking the end of the clip.

Well, I sent this topic to the mailing list but I did some research myself and found that Nyquist is better equipped for higher level operations than for sample-by-sample processing. However this particular idea should be possible with the following functions:
-forum.de/download/edgar/nyquist/nyquist-doc/manual/part6.html#index164

maxduration: amount of samples that each negative clipping area is allowed to contain. In practice this defines the maximum amount of samples that the algorithm will look ahead to find the very high slope (marking the end of the clip) after having found the very low slope (start of the clip). Not implemented in the pseudo-code because this fits in the observation-first principle as described above.

slowness and inability to work with a whole 3 minute track except on the fast machines with a lot of memory (this is as I understand it really a known problem with memory management in the Audacity implementation of Nyquist)

manual deamplification of the audio is necessary before running Clip Fix (that could easily be added by someone who knows what they are doing, in my experience a 10 - 15 dB deamplification is necessary).

The amount of de-amplification depends on how much the audio is clipped and on the threshold level that is set. Determining a precise amount of de-amplification would be quite tricky and would require a pre-scan, but it could be either set with a second slider, or for a more simple interface could be set to a generous amount, and the waveform normalized post de-clipping. The problem with automating this task by either method is that if the effect is applied to a selection, rather than the whole track, there will be a noticeable jump in amplitude in the processed section.

I agree with all of that, but the prior de-amplification (even if simply a fixed generous amount) is possibly more important to put in, because if selections are processed some manual re-adjustment of levels is almost always going to be necessary whether Clip Fix normalises afterwards or not. If Clip Fix worked more efficiently it would probably be better in most cases to simply apply it to the whole track, just as applying noise removal to the whole track may leave the whole sounding more uniform.

I am using Waveform Audio Player plugin but only get MP3 audio files to play. All my files are WAV format. Can this plugin work with WAV as well or is there another plugin I can use to play WAV files?

I have done some testing to ensure I provide the most up-to-date information, and the plugin was working correctly with WAV music files. The waveforms were created correctly, and the song played with no issues.

Firstly, the audio playback "glicthes" quite often. I don't really know how to describe it precisely, it just "crackles" and doesn't play the sounds like it's supposed to. I believe this is most likely due to something being wrong in my audio configuration or something, but since I don't have any knowledge in this domain I don't understand it very well. For whatever reason, when I start my screen recorder (Kazam), the audio playback seems to improve (kind of) but it doesn't really work that well, and it wouldn't really have been a viable solution anyway.

Secondly, Waveform seems to have problems with native .so linux plugins. Funnily enough, the Windows plugins I run using LinVst (namely Spitfire Labs, BBC Symphony Orchestra and Kontakt Player) work perfectly fine. However, Decent Sampler (which has a Linux version) just... doesn't work. Nothing shows up, and there's no error message either. It only shows an exclamation mark next to the plugin ; here's the screenshot :

I did everything you told me (including the swappiness change) and restarted my computer, but I am still encountering the same problem. I've tried to record it, but again, the issue magically disappear when i start my screen recorder (I've got no idea why) so I just took a video with my phone instead :

And yes, it works with Carla. But when I use Carla in Waveform, it won't load anything (whether it is Sfz files in Patchbay, or VSTs in Rack). This might be because WF fails to load several plugins when scanning (apparently). Here's a screenshot :

Try running Waveform from the command line to see what (if anything) it spits out when you try to add the plugin.
Also try installing and running Ardour, which is very picky about plugins and may give you a useful error message, such as a plugin ID conflict.

You'll also want to try closing Waveform and then (re)moving the DecentSampler folder from .config. While experimenting I did manage to get a "!" out of Waveform on the plugin, after starting with the VST2 version and then installing the VST3 version, but haven't been able to replicate it.

Hmm, I haven't found a command for Waveform in the terminal. I tried searching with "apropos waveform", "apropos audio", etc. but it doesn't seem possible to run it from the command line, unfortunately. And about Ardour, thanks for checking ; I tried it once (when I was looking for better DAWs than LMMS) but I didn't quite understand how to use it.

I can't recall where I got that DS works with WF, maybe in some combinations of previous versions, but it doesn't work now with recent WF and DS.
So if you really need it - you can wrap it with wine or Carla or Ildaeli.

I installed the Windows version and runned it with LinVst in WF, and now it opens (what a big progress, wow ), except I can't do anything with it (when I click on a button for exemple, it doesn't do anything).
For now, I think I'll just use Waveform as my main DAW and add the DS instruments afterwards in LMMS if I really need it then...

I wanted to share my first open source project with you. It's a seekbar plugin for the DeaDBeeF audio player (only version 0.6 or higher) with a waveform visualization underneath and still under heavy developement.

With the upcoming DeaDBeeF 0.6.2 release it will be possible to replace the stock seekbar with this plugin. I took that oportunity to improve the visuals by adding a border (can be disabled) and made some code refactoring.
