STILL MOON

The Science of Sonic Relaxation

Still Moon is a next-generation sleep aid leveraging procedural audio synthesis to create organic, non-repetitive soundscapes. Unlike traditional MP3 loops that the brain eventually recognizes as a pattern—potentially disrupting the relaxation state—our audio engine generates every raindrop, thunderclap, and fire crackle in real-time. This ensures that no two minutes of listening are ever identical, mirroring the chaotic beauty of the natural world.

Understanding Colored Noise for Sleep

While "white noise" is a common term, it is often too harsh for sleep. Still Moon focuses on the warmer, deeper spectrums of colored noise:

• Brown Noise (Red Noise): The deepest of all, mimicking the roar of a distant waterfall or heavy thunder. Its low-frequency dominance is excellent for masking external disturbances like traffic or snoring.
• Pink Noise: Ideally balanced for human hearing, pink noise (like steady rain or leaves rustling) has been shown in clinical studies to enhance deep sleep and improve memory consolidation.
• White Noise: Useful for active focus and privacy masking in office environments.

Why Procedural Audio Matters

Your brain is a pattern-matching machine. When you listen to a 3-minute recording of rain on a loop, your subconscious eventually detects the repetition. This "loop recognition" can cause a subtle alertness response, preventing you from entering the deepest stages of REM sleep. By calculating audio mathematically in the browser, Still Moon creates a truly infinite, ever-evolving backdrop that allows your mind to fully disengage.

Privacy-First Mental Health

In an era of data tracking, your sleep habits should remain private. Still Moon is designed with a zero-data philosophy. The application runs entirely client-side (on your device). No audio is streamed from a server, no usage data is collected, and no trackers follow you. It works perfectly offline, making it ideal for airplane mode or camping trips. Note: While Still Moon itself collects nothing, our host (Cloudflare) may collect limited technical data (such as your IP address) for security and performance purposes.

Curated Soundscapes

Our presets are not random mixtures but carefully orchestrated sonic environments:

• Stormy Cabin: Combines heavy rain (Pink Noise) with the cozy warmth of a fireplace (crackles and pops) and distant rolling thunder (low-frequency impulses).
• Deep Space: Utilizes low-frequency oscillation to mimic the hum of a starship engine, perfect for masking tinnitus or jarring city noises.
• Coastal Dawn: Blends rhythmically modulated pink noise (waves) with gentle high-frequency sizzle, simulating a beachside morning.

Ideal Use Cases

Still Moon is versatile and can be used for more than just sleep:

• Insomnia & Sleep Apnea: Use the heavy rain or brown noise presets to drown out intrusive thoughts and silence the environment.
• Tinnitus Masking: The "Deep Space" or "Singing Bowl" engines provide consistent, broad-spectrum frequencies that can help mask the ringing of tinnitus.
• ADHD & Deep Focus: The "Deep Focus" preset creates a "colored noise wall" that blocks out distractions, perfect for studying or coding.
• Baby Sleep: The gentle, womb-like frequencies of brown noise are highly effective for soothing infants.
• Meditation & Yoga: Set the Singing Bowl drone for a consistent anchor during your mindfulness practice.
