Description:
Amplifies the ringing sound emitted by Nirnroots. It was amplified to the extent possible without clipping or scratching noises.

Reasoning:
Many mods reduce the emitted noise made by Nirnroots. Understandably, some mods reduce that sound too much. This mod is for those of us who would like to still be able to hear that noise.

Related mods:
Sound of Barenziah: Barenziah's gems now emit the same ringing noise, making them easy to locate without altering quests (which often causes problems). http://skyrim.nexusmods.com/mods/16018/
