Shine 4

Shine 4 is a high-resolution harmonic exciter engineered for controlled spectral enhancement and precise harmonic generation. Featuring targeted excitation via stepped frequency control and four unique Exciter models, it allows you to move beyond broad brightness to achieve both subtle clarity improvements and deliberate tonal coloration. Real-time dual-layer FFT analysis ensures you can monitor exactly how the harmonics and levels change, maintaining complete accuracy while shaping your signal.

"Fully coded DSP & GUI — no images, no SVGs, no skins. Pure signal."
