Build a quiet room around you for focus, rest, and sleep. Mix rain, fire, ocean, wind, birds, and streams on a canvas, place each sound where it belongs, and return to the same space whenever you need it.
prostir zvuku is a spatial nature sound mixer for macOS that lets you build a quiet, immersive room around you using natural sounds. Instead of playing a flat audio track, you place individual sounds like rain, fire, ocean, wind, birds, and streams onto a spatial canvas, positioning each one exactly where it belongs in your personal soundscape. The app runs natively on Mac, uses Apple's HRTFHQ binaural engine for realistic spatial audio, and works entirely offline after download.
You start with a library of nature sounds — rain, fire, ocean, wind, birds, forest, thunder, crickets, and streams — then drag each layer onto a canvas. Move a sound left, right, near, or far until the room feels right. Keep rain wide and soft, put fire close to you, let the ocean sit far away, or place birds just outside the edge of attention.
Saved rooms stay accessible from the notch or menu bar without opening the editor. You can pause, switch presets, or adjust the scene in a single motion. The app is designed to be always close, never in the way.
Set a timer for a work session, a reset, or sleep. When time runs out, the scene quiets gradually instead of stopping with a click. This makes it especially useful for winding down or for timed focus blocks where you don't want an abrupt interruption.
With AirPods Pro or AirPods Max, the sound field stays anchored to the room as you turn your head. Spatial audio itself works on any output — Mac speakers, wired headphones, or any Bluetooth headphones — but head tracking adds an extra layer of realism that keeps the room fixed in space.
"Place nature around you, not just in front of you."
Most nature sound apps play a stereo mix that sits in front of you. prostir zvuku treats sound as a physical space you can shape — rain wide and distant, fire warm and close, birds at the edge of attention. Combined with the free tier that includes the full sound library, spatial canvas, and head tracking, it offers a genuinely different approach to focus and rest without locking core features behind a subscription.
you want a spatial, customizable nature soundscape that works offline, respects your privacy, and doesn't require a subscription. It's especially worth trying if you already use a Mac for deep work, need a gentle sleep timer, or want to experiment with head-tracked spatial audio using AirPods. The free version gives you up to 3 layers and a 5-minute timer, so you can decide if the spatial canvas fits your routine before considering the one-time Lifetime Pro upgrade.
