ASMR Soundscape Lab
Position sounds around your head in 3D space. Every sound generated live — no loops, no files.
How each sound works
Brown noise
Brown noise concentrates energy at low frequencies, creating a deep rumble similar to a waterfall or strong wind. Research suggests it helps mask higher-pitched distractions and promotes relaxation. The name comes from Brownian motion (random walk), not the color.
Brown noise guide →Pink noise
Pink noise balances energy equally across octaves, producing a sound that feels natural and even — like steady rainfall or rustling leaves. Studies published in Frontiers in Human Neuroscience found pink noise during sleep can improve memory consolidation.
Pink noise guide →White noise
White noise contains equal energy at every frequency, creating a bright, full-spectrum sound. It's the most effective noise color for masking speech and environmental sounds, making it popular for open-plan offices and nurseries.
White noise guide →Binaural beats
Binaural beats play slightly different frequencies in each ear — your brain perceives the difference as a rhythmic pulse. Delta beats (1–4 Hz) are linked to deep sleep, alpha (8–13 Hz) to relaxation, and beta (14–30 Hz) to focused attention.
Binaural beats guide →Rain & nature sounds
Natural soundscapes activate the parasympathetic nervous system — your body's "rest and digest" mode. A 2017 study in Scientific Reports found nature sounds reduced sympathetic nervous system activity and improved cognitive performance compared to artificial noise.
Rain sounds guide →Spatial audio & ASMR
Positioning sounds around your head activates the same neural pathways as real-world spatial hearing. For ASMR listeners, spatial positioning intensifies the "tingles" response — the brain treats carefully positioned audio as more present and immersive than flat stereo.
How ASMR affects the brain →Frequently asked questions
How does the spatial audio work?
The Soundscape Lab uses the Web Audio API's HRTF (Head-Related Transfer Function) panner to position sounds in 3D space around your head. When you drag a sound on the circular stage, it updates spatial position in real time. Headphones are required for the full effect — speakers collapse the 3D field into stereo.
Are the sounds real recordings?
No. Every sound is generated procedurally by your browser using mathematical algorithms. Brown noise uses a random-walk integration, rain uses filtered noise with random impulses, and fire uses stochastic crackling bursts. This means audio never loops audibly — each session is unique.
What headphones work best?
Any over-ear or in-ear headphones work for spatial audio. The HRTF processing is built into the browser's audio engine. Higher-quality headphones with good stereo separation will produce a more convincing 3D effect, but even basic earbuds deliver noticeable spatial positioning.
Does the timer stop all audio?
The timer gradually fades all sounds to silence over the final 30 seconds, then stops playback completely. This gradual fade is designed for sleep — an abrupt stop could wake you.
What does Meander mode do?
Meander slowly drifts the volume and spatial position of each active sound, creating organic variation. Instead of static ambient noise, the soundscape breathes — rain shifts subtly to the left, wind grows and recedes, fire crackles from different angles. This prevents auditory habituation where your brain tunes out constant sounds.
Which preset is best for studying?
The Focus preset combines pink noise with stream sounds and beta-frequency binaural beats (16 Hz). Pink noise masks distractions without being intrusive, flowing water provides a natural texture that aids concentration, and beta binaural beats are associated with alert, focused brain states.
