Hi, everyone. I'm not a musician but you could say I'm an audiophile cuz I want everything to be in the highest possible quality. Recently I noticed some of my music has clipping, so using Audacity I fixed them (some of them even became perfect, as if there was never any clipping). But I wanna check ALL of my music (which is 65GB+ all in WAV format). Through internet search I found this forum and to be precise - this old topic: viewtopic.php?t=15359 But these scripts in the topic don't work at all, so I kept looking and came across this (the screenshot is from DuckDuckGo):
You'd think I've found the answer... BUT! The above screenshot says that the file can have its volume increased by the number of volume adjustment without causing any clipping. However, checking a WAV track with Audacity, it already has clipping (the red color is clipping). According to this:
Code: Select all

that song can be volume increased without clipping by 1 dB. But since it already HAS clipping, I don't see how that will help. Something here doesn't fit but I'm lost and I need some help to figure it out. Is it possible that "volume adjustment" displays the wrong digit and it should be -1, instead of +1?
This is what the track looks like in Audacity, when the option to display clipping is ON:
These red lines make me seriously doubt that increasing the volume by even +1 would do any good and will most probably make things even worse.
