Soundie

Soundie とは？

Soundie mixes 100+ handcrafted ambient sounds into your perfect night — rain over a crackling fire, a slow delta pulse underneath. Every sound has its own volume and stereo position, and binaural beats are synthesized live, not played from recordings. It's fully offline: no account, no ads, no tracking. Night Journeys reshape your mix while you sleep, Breathe mode syncs the soundscape to your breathing, and a gentle alarm fades you awake. Plays all night with the screen off.
