Choose a soundscape
All sounds synthesized in your browser — no audio files required. For Deep Focus binaural beats, use stereo headphones.
A browser-based ambient sound player that synthesizes relaxing soundscapes using the Web Audio API — no audio files or downloads needed. Choose from 7 carefully crafted presets: Rain (with realistic individual drop bursts), Ocean Waves (half-rectified LFO for natural swell and crash), Fireplace (rumble + crackle bursts), Forest Wind (sweeping bandpass modulation), Brown Noise, White Noise, and Deep Focus (pink noise masking + 10 Hz alpha binaural beats). Includes a sleep timer and volume control.
