How to get this track’s intro sound? Is that some sort of sound effect?

Backwards piano + guitar + cymbal.

Hi @Createus !!!
There are many obvious tools .
I think you need to personally contact the author and ask for details .

Probably woudn’t even to reverse audio tracks, could just grab a sustained pad, piano or guitar sound and automate the level. And of course a sneaky cymbal roll as an uplifter

I bet there is a tutorial on Youtube.

The answer is the first reply. It’s not harder than that.

Any chord/notes on piano + guitar. Bounce to audio and reverse. You don’t get the same sound with volume automation - to get that “inhaling” sound you need to reverse the audio.
