What is that strange sound heard while exploring underground?

[Dreed]

The sound has a direction and I guess it hints at a nearby treasure and/or location. I have been trying to follow the sound but I cannot determine whether (1) the place I have visited was causing the sound, and another one has started after I have explored the place, or (2) I was never able to find the place the sound was coming from.

The sound is a mysterious, glowing-ish one.

Does it really point at special places or treasures? I could not find such information on the internet.

Edit:
Here, I have uploaded the sound file, it starts after the third second:

- the sound comes from a specific direction when heard in-game
- getting further from the sound makes the sound not play anymore
- it is heard with any of the background theme musics, not just specific to the one I posted

You probably just heared a monster (maybe Mushroom one, since you said "Glowish"), the chest you found was just luck

I don't think it comes from a monster.

Here, I have shared the sound file. It starts after the third second.

Does it sound familiar to anybody?

That is literally part of the music, nothing more.

I don't agree it is part of the music because:
- the sound comes from a specific direction when heard in-game
- getting further from the sound makes the sound not play anymore
- it is heard with any of the background theme musics, not just specific to the one I posted

You can desactivate the music in the options

The only thing I hear in your shared audio clip is the original underground music. Compare your clip to this youtube video that starts with the same sounds I'm hearing at 3 seconds from your clip:

it is a sound in the music it's just the sound file

You must be right Drag, for some reason I never thought of checking the undergorund track.

Since that exact part of the sound happens to come from my left earphone, and I was paranoically searching for treasure, I must have associated the sound with treasure. (Also, that part of sound can very well fit to a scenario where you are hinted towards a treasure, hehe)

Good that now I know this, I can just continue exploring on my pace instead of searching for something that does not exist. :)
