Aetheria: Your Spatial Sanctuary Escape the flat world. Enter Aetheria. Aetheria is not just another noise app. It is a high-performance spatial audio engine designed for those who demand more from their mental space. Whether you are deep-lining code, seeking restorative sleep, or reclaiming your focus from ADHD, Aetheria constructs a living, 3D environment that breathes with you. THE SPATIAL AUDIO DIFFERENCE • Standard apps play static, two-dimensional loops. Aetheria utilizes a proprietary 360° sound stage. • Active Spatialization: Use your screen as a canvas. Drag a crackling fire to your left, heavy rain behind you, and wind in the pines above. • Dynamic Orbit: Enable "Motion" to let sounds slowly rotate around you. This prevents auditory habituation, keeping your brain engaged in a flow state for longer periods. NEUROSCIENCE, NOT JUST NOISE We don’t just offer "relaxing sounds." We offer cognitive control. Layer your environment with scientifically calibrated binaural beats to tune your brain state: • Delta (2.5 Hz): Deep, restorative sleep. • Theta (6.0 Hz): Meditation & creative visualization. • Alpha (10 Hz): Relaxed alertness & stress reduction. • Beta (20 Hz): High-level focus & cognitive performance. • Gamma (40 Hz): Peak concentration (Pro). CINEMA-QUALITY SOUND BANK Every sound in Aetheria is 100% gapless and high-fidelity. • The Elements: Heavy Rain, Distant Thunder, Ocean Swells, Forest Wind. • The Colors: Deep Brown Noise (ADHD optimized), Pink Noise, and White Noise. • The Atmosphere: Coffee Shop, Cello Drones, Tibetan Bowls, and 432Hz Tones. PRIVACY AS A FEATURE In an era of data harvesting, Aetheria is a sanctuary. • Zero Tracking: We do not collect your usage, location, or identity. • 100% Local: The audio engine runs entirely on your device. • Offline Ready: No internet required. Perfect for flights or deep-work zones. OWN YOUR TOOLS. NO SUBSCRIPTIONS. We believe mental health tools should be owned, not rented. • Free Tier: Generous access to core sounds and spatial presets. • Aetheria Pro: A single, one-time purchase. No monthly fees. No recurring "wellness" taxes. Unlock the full library and Gamma waves forever. Transform your headphones into a sanctuary. Download Aetheria.
