About these thunder sounds, uses and license
Brewing, rolling thunder: rumbles arrive at random moments from different distances, the way one thunderclap reaches you along many paths, over a low, wobbling bed. Some variations are close with a few cracks up front, others are distant rumble only. For the strike itself, use Lightning. Every press of New in the editor brews a different thunder; these 12 are a fixed selection so the links stay the same.
Good for
- Heavenly tribulation building up in cultivation games
- Storm ambience and weather
- Ominous moments before a boss
- Combine with Lightning for a full strike
Tweaking tip
Play Lightning first and this a moment later to get a strike followed by its echoing rumble. Open any variant with Edit to change it with sliders.
