Soundscapes

Six environments.
Infinite combinations.

Every layer synthesized live in the browser. No audio files. No loops. Each second sounds unique.

🌧
Rain on Glass
Steady downpour with natural intensity variation. Close your eyes and you're inside.
White noise · HP/LP filtered · LFO
☕
Café Murmur
Warm mid-range chatter, just enough to feel alive without being distracting.
Pink noise · Band pass · Peaks
🌌
Deep Space
Sub-bass brown noise beneath a 42 Hz sine drone. The sound of nothing, everywhere.
Brown noise · 42 Hz drone · LFO
🌲
Forest Wind
Rustling leaves, slow wind gusts, open air. Feels like a clearing in the trees.
Pink noise · Wind gust LFO
🔥
Fireplace
Low warmth with high-frequency crackle. The coziest sound in existence.
Brown noise · Crackle modulation
🏙
City Hum
Urban noise at a distance. Traffic drift. Low rumble. The world going on without you.
