So, something I noticed is that after playing Terraria for a while, my ears start aching. And it's not because my headphones don't fit, it's because some sound effects in this game are
really shrill.
If you're like me and you wince every time you use a mana crystal, you should give this a shot! It replaces some sound effects with edited versions that have had their edges dulled, so to speak, making Terraria's soundscape that much less grating.
Affected sounds include the teleport sound, mana crystal sound, some particularly loud types of gunshots and lasers, mining "tinks", and some of Mothron's, Mushi Ladybug's, and Moon Lord's voices.
NOTE: "Sound packs" may break if they are enabled after the affected sounds have played in-game. For best results, enable this pack as soon as you launch Terraria!
