Revol9

Revol9 is a sound-based wellness app built around Solfeggio tones and scientifically recognized frequencies that support both mental and physical well-being.

HEALING FREQUENCIES
Explore a curated library of Solfeggio frequencies (174 Hz – 963 Hz), each associated with specific therapeutic benefits — from pain relief and emotional release to intuition and spiritual connection.

TINNITUS RELIEF
Candle Mode generates broadband noise (pink, white, brown) with optional EQ shaping, designed to mask tinnitus and provide immediate relief. Volume is safety-capped to protect your hearing.

AI-COMPOSED AUDIO
Nine Engine creates unique ambient compositions tailored to your selected frequency and mood — no two tracks are the same.

INSTANT GENERATIVE AUDIO
Nine Flow produces real-time procedural soundscapes directly on your device. No network needed, no waiting — immersive audio starts instantly and evolves continuously.
