I cant edit lufs in foobar

is there a way to reduce to reduce the lufs with foobar?

There's no plugin for that? Only measurement?

I wonder if this is related to your other threat https://hydrogenaud.io/index.php/topic,127776.0.html. I hope you know that LUFS just refers to loudness. Your other threat seems to feature some kind of compression or equalizing or something, not just loudness adjustment.
You can lower your LUFS by 1 dB or 1 LU by turning down foobar2000 volume level by 1 dB. If you for some reason need to edit playback level of individual tracks you edit the ReplayGain values of said tracks.

i want to edit the lufs and save the file with the modification, not only in foobar playback.
If foobar cant do it, what software you recommend?

Look into the ReplayGain (RG) tag.  You don't need to use the RG scanner to set the tag, you could just write a -1dB value into the tag and then any player which implements RG will play the track with -1dB gain.
It's your privilege to disagree, but that doesn't make you right and me wrong.

just to be clear, what is the difference between lufs and db, i mean with the lufs you can work in a more precise scale, thats it? There's some quality difference if i reduce the loudness with one or the other

Can you explain this? the first one was done by db reduction (-12,6db) which result in 90.1db. The other by -15.8lufs, so then why the wave looks so different (the loudness its exactly the same)

which is better?

LUFS is the loudness measurement unit of the ITU-R BS.1770 standard meant for loudness normalization in broadcasting. Decibel (dB) is just a relative unit of measurement - it doesn't natively relate to audio in any way. When you use just dB without any further clarifying unit you can only describe a difference. But if you combine it with something else you can talk for example about audio loudness, see for example dBSPL. Or dBFS when describing loudness level related to digital fullscale, like LUFS.

There is no difference in precision.

You need to describe what has been done to those tracks. It's very obvious that they have not gone through similar processing at all. Be step-by-step precice.

And it's impossible to say which is better since there is zero knowledge what you are showing. Objectively better is the one that is closer to original. Subjectively better is the one that sounds better to you. The lower track looks more dynamic, but if it's just result of using random mutilations, it is definitely not what the artist has intented or what the track should sound like.

As Case says, LUFS is about broadcasting – ie getting the "best" out of a limited bandwidth.  If you are interested in high fidelity, you shouldn't really be going that path.  "Best" is in the ear of the beholder, but emphasis and compression will be in the mix.

Are you perhaps confusing this with dBFS, where the 0dB reference point is the maximum signal the channel can handle?  This particularly applies to fixed-point digital representation, limited to (typically) 16 or 24 bits (and even if more bits or floating point is used, the DAC is only going to be 24 bits anyway).

dBFS is not always a good indicator of signal power / volume.  It is not difficult to construct a waveform which has very little audio power (and would barely register on a traditional VU meter) but still maxes out a digital channel.  dBFS is however essential for monitoring whether the digital channel is clipping the signal.
