Ambience player & focus timer

Focus Room

A calm room for your screen: ambience, slow visuals, focus timers, clocks and big signs.

Launch Focus Room → Tutorials

Focus Room plays Soundscape Atlas ambience scenes as a playlist with smooth crossfades, shapes them with a master equalizer, room reverb and stereo width, and fills the screen with slow, seamlessly repeating generative backgrounds. A Pomodoro, 52/17 or custom focus timer rings gentle chimes, a sleep timer fades everything out, and a local session log shows your week as a heatmap. The Display tab turns the screen into a clock (analogue, flip, binary, word clock in 17 languages, world clocks), a countdown to any moment in any time zone, a stopwatch with laps, named timers, a Tabata/HIIT/EMOM interval timer, a presenter timer or a big sign. Nothing plays until you press Play, and nothing leaves your device.

Features

  • Ambience playlists

    Put scenes in order with their own lengths, shuffle or repeat them, and let each one melt into the next with an equal-power crossfade of up to 30 seconds.

  • Built-in and Soundscape scenes

    Seventeen scenes from brown noise to a fireside and the Soundscape Atlas worlds, plus your own Soundscape mixes from a file or “Open in Focus Room”.

  • Graphic EQ and cuts

    Eight octave bands from 63 Hz to 8 kHz, low cut and high cut, with a live response curve computed from the same filters the browser runs.

  • Room, width, limiter and presets

    Place everything in a small room, a hall or a cave, widen the stereo image, keep peaks soft, or start from Warm, Bright, Far away or Small room.

  • Nine generative backgrounds

    Fog, aurora, caustics, rain on glass, stars, zen sand, a lava lamp, Lissajous curves and light rays — seamless, seeded, in eight colour themes, calm with reduced motion.

  • Art backgrounds, loops and props

    Thirty-nine pictures in seven styles, eight seamless moving loops and thirty props — plants, tea, a sleeping cat — to drag onto the stage.

  • Kiosk mode

    Full screen with a large clock, controls that hide themselves, a screen that stays awake while it plays, and Esc to leave.

  • Focus and sleep timers

    Pomodoro, 52/17 or your own cycles with soft chimes and a calendar file of the plan; a sleep timer fades the room out and stops.

  • Session log and heatmap

    Finished focus time is logged in this browser and shown as a twelve-week heatmap with your streak; export it as CSV or clear it.

  • Clock faces and world clocks

    Digital, analogue, flip, binary or a word clock in 17 languages, with up to six world clocks in a strip — full screen on a TV, tablet or second monitor.

  • Countdowns in any time zone

    Days to seconds until a moment anywhere, working days without weekends and public holidays, a calendar file, and New Year in every time zone.

  • Stopwatch, laps and named timers

    Laps with the best and the slowest marked and a CSV export, plus kitchen or exam timers that run side by side and chime when they end.

  • Interval timer with cues

    Tabata, HIIT, EMOM or your own rounds with chimes, 3-2-1 beeps and spoken cues, and a cue-track WAV to play along on any speaker.

  • Big sign and presenter timer

    Text as big as the screen allows, in seven colour pairs or as a marquee, kept in a link; and a talk timer that turns amber, then red.

  • Render to WAV

    Mix the playlist with its crossfades and effects into a WAV file on your device — the same renderer as the playlist tool.

  • Private and local

    Rooms autosave with recent rooms, undo and redo, room files and share links; the session log never leaves the browser.

Built-in tools

Focus Room uses these tools. Each one also has its own page and works on its own, in the browser, through the JSON API and through MCP.

For AI agents

Focus Room runs on a deterministic engine. The same functions are available as tools with a JSON API and MCP, so scripts and AI agents get exactly the results the app shows.

Frequently asked questions

Will Focus Room start playing by itself?

No. Sound only starts when you press Play or test a chime. Opening a room, a template or a link never plays anything.

Where do the sounds come from?

Most scenes are generated on your device by the Soundscape Atlas audio engine from a seed: noise colours, rain, wind, water, fire, hum and drones. Some Soundscape worlds and your own Soundscape scenes contain real field recordings from Wikimedia Commons; those stream from upload.wikimedia.org when they play, and the credits list them.

How do I bring my own Soundscape mix in?

In Soundscape Atlas choose File → Open in Focus Room, or save the scene as a .soundscape.json file and open it here with Ctrl+O. It becomes a playlist entry. Audio you imported into Soundscape Atlas stays in that app and is left out.

What does equal-power crossfade mean?

While one scene fades out and the next fades in, their gains follow a cosine and a sine curve. The sum of their powers stays constant, so two different ambiences neither dip nor bulge in loudness during the change.

Do the backgrounds use a lot of power?

They are drawn at 15, 30 or 60 frames per second (30 by default) at screen resolution, and pause in background tabs. With reduced motion the app shows still images that crossfade every 20 seconds instead. Art pictures draw nothing after loading; moving loops are short H.264 clips that the graphics hardware decodes, play muted, pause in background tabs and show a still picture with reduced motion.

Where do the art backgrounds and props come from?

They were generated for Focus Room with AI image and video models through OpenArt, picked by hand and ship with the app. They show no people and no brands. Rooms and share links store only their names, so a shared room shows the same pictures for everybody and nothing is uploaded.

What is stored about my focus sessions?

Only the date, start time, focused minutes and room name of each finished block, in this browser. The log is not part of room files or share links. Export it as CSV or clear it in the Log panel.

Why does the screen stay on?

In kiosk mode Focus Room asks the browser for a screen wake lock while it plays, so the display does not sleep. It is released when you leave kiosk mode, pause or switch tabs.

How do I put a clock or a countdown on a TV or second screen?

Open the Display tab, pick Clock, Countdown or another mode and press Full screen. Esc leaves it. While a display runs full screen, Focus Room asks the browser to keep the screen awake.

How are working days counted in a countdown?

From today up to the day of the event, without the event day: every date that is not one of your weekend days and not a public holiday of the chosen country. Holidays come from the RuleDate data for 16 countries (2024–2030); company holidays are not included.

Can the interval timer speak?

Yes, if you switch on spoken cues: the browser’s own speech voice says “Work”, “Rest” and the round. Voices differ between devices and some have none; the chimes and beeps always work, and the downloadable cue track contains only chimes and beeps.

What does a sign link contain?

The text, the colours and the marquee setting of the sign, inside the link after #sign=. Nothing is uploaded; whoever opens the link sees the sign full screen.

Can I use the rendered WAV in my own videos?

Generated scenes are yours to use. If a rendered playlist contains Wikimedia Commons recordings, follow their licences: the credits list each recording with its licence and author.

Limitations

What Focus Room does not do (yet):

  • Playback follows the browser’s audio clock; phones may pause audio and timers in background tabs or with the screen off.
  • Crossfades are triggered by a page timer: in background tabs a change can start up to about a second late.
  • The limiter is a soft clipper (tanh knee), not a look-ahead broadcast limiter; very loud mixes can still sound compressed.
  • Recordings come from Wikimedia Commons and need a connection; the server playlist tool renders only generated scenes.
  • The WAV render is limited to 12 scenes and 10 minutes; long rooms are rendered with shortened scenes.
  • Wake lock and full screen depend on the browser; some browsers ignore them or ask first.
  • The session log lives in this browser only and is not part of backups made with room files.
  • Generated scenes imitate rain, surf or a café with filtered noise; they are not recordings of those places.
  • Art backgrounds and props are AI-generated pictures, not photographs or paintings of real places; small details can look odd up close.
  • Moving loops are about six seconds long and 1280 pixels wide: on very large screens they look softer than the pictures, and the loop point is a short crossfade.
  • You cannot add your own pictures as backgrounds or props; rooms only refer to the built-in art by name.
  • Clocks follow the device clock and its time-zone data; countdowns far in the future use today’s time-zone rules.
  • Phones and tablets may pause timers, chimes and spoken cues in background tabs or with the screen off; iOS mutes web audio with the silent switch.
  • The stopwatch counts to the hundredth of a second on screen; browsers deliver timer events in steps of a few milliseconds.
  • The word clock rounds to the nearest five minutes and uses one common everyday phrasing per language.
  • Big signs use the bundled Noto fonts; rare Chinese, Japanese or Korean characters and emoji are not included.
