Build my soundscape: how this works, in words
- What it does
- Turns a goal, or a short phrase you type, into a layered background soundscape that keeps playing until you stop it or the fade-out timer ends.
- What it accepts
- A goal (sleep, focus, calm, reading, meditation or noise masking) or a plain phrase such as rain on a cabin roof. The phrase box is a keyword matcher running on your device, not a language model, so the same words always build the same mix. No audio is uploaded and no file is needed.
- What you control
- Goal selection, the phrase box, per-layer volume, mute and solo, a master level, a fade-out timer, saving a mix to this browser and copying a share link that encodes the mix in the URL.
- What changes
- Audio only. Each matched keyword adds a layer you can then rebalance; the fade-out timer lowers the master level to silence over the period you set. The active layers and their levels are listed as text.
- What it illustrates
- How a soundscape is assembled from independent layers, and how steady broadband texture behaves differently from sparse intermittent detail when it is sitting in the background.
- What it does not claim
- Steady background sound is a listening preference that many people find makes a room feel less distracting. That is not a medical treatment, and nothing here is claimed to treat insomnia, anxiety, ADHD or any other condition.
- Keyboard and screen readers
- Goals are labelled buttons, the phrase box is a normal text input, and every layer exposes a named range input plus mute and solo buttons with pressed state, so the whole mix can be created and adjusted by keyboard. The current mix is described in text, not only by fader positions.
Common questions
- Does building a soundscape use an internet connection or an AI service?
- No. Every layer is synthesised locally by your browser's audio engine. Nothing is uploaded, generated in the cloud, or streamed.
- How does describing a scene in words work?
- The phrase box is a plain keyword matcher that runs on your device. Words like rain, cabin or frogs map directly to layers. There is no language model and no API call, so the same phrase always builds the same mix.
- Will a soundscape help me sleep or concentrate?
- Many people find steady background sound makes a room feel less distracting, and masking noise can make intrusions less noticeable. That is a listening preference, not a medical treatment, and results vary between people.
- Are my mixes saved anywhere online?
- No. Saved mixes stay in this browser's local storage. A share link encodes the mix inside the URL itself, so no account or database is involved.

The same engine powers the Sound Blender, where you can browse layers by category, and the Sound Library explains where each sound comes from.
