Scintillate: Free Reverb Sparkle Engine by Sweet Audio
Scintillate is a free spectral sparkle engine by Sweet Audio that won the 2026 KVR Developer Challenge. The plugin generates harmonic sparkles within the frequency spectrum of a conventional reverb, adding air and shimmer without a separate reverb unit. You can download it directly from the developer's site with no sign-up required.
How it works
Scintillate spawns short-lived spectral grains at adjustable rates and decay times, layering them onto any incoming signal. The result ranges from subtle fairy-dust textures to dense, glittering clouds. Because it targets the spectral domain, the effect blends naturally with existing reverb tails or dry signals alike.
