Whether you need to focus on complex projects, ease into deep meditation, or fall into a restorative sleep, Cosmosis lets you orchestrate your perfect sonic background.

// THE PLANETARY SYNTHESIS 

Journey through the planets, from the sun-scorched plains of Mercury to the dark, windswept ice-giant Neptune. Each celestial body features a signature ambient theme paired with a dedicated Solfeggio frequency to help harmonize your mind.

// THE SONIC MIXER: CRAFT YOUR UNIVERSE 

Take complete control of your auditory environment with our precision mixer. Independently adjust and layer four distinct sound channels for each planet:

Music: Gorgeous, rich ambient melodies tailored to each planet.
Ambience: A low-frequency starship cabin hum to ground your environment.
Solfeggio Frequencies: Planetary-resonant therapeutic frequencies (174Hz to 852Hz) to promote healing and calm.
Green Noise: A soothing, organic frequency spectrum designed to mask distracting background sounds.
