Hello there :), this time i'm creating this post to see if there's a possibility to add this mod named "Sound Filters"
Here's the link: https://minecraft.curseforge.com/projects/sound-filters
The mod adds sound effects to the caves like reverb, and mutes others when you're underwater, or behind a wall, i would really love this mod for my server (i have some friends who put music discs all the time for example) i hope you guys can add it, thanks in advance.
