# Infinite Voidsong

> A free web tool that generates endless background soundscapes for focused work, with timed work-and-break sessions and an audio-reactive tunnel. It runs entirely in the browser. Made by Sinaida Krivchenko, a Prague-based new media artist.

## What it is

Infinite Voidsong plays sound that is generated live in the browser with the Web Audio API. Six layers (stream, rain, rain with thunder, birds, crickets, wind) can play short CC0 field recordings, looped with random start points and cross-fades; they download from the same site the first time a layer is switched on, and a generated version plays if they cannot load. Nothing else is downloaded beyond the page itself. You mix up to four layers at once.

- Noise: white, pink, brown.
- Nature: rain, ocean, stream, underwater, wind, campfire with crickets.
- Places: café, library, train cabin. The murmur is built to be unintelligible.
- Machines: fan hum, cassette tape hiss, shortwave radio static (no voices).
- Music: generative drone, lo-fi, plucks, synthwave, Berlin-school sequencer, house and chillhop. All instrumental, steady, with no drops.
- Tone: one steady tone with adjustable pitch.
- Focus Boost: a fast pulse (12 to 20 times a second) on the music layer, with depth and rate controls.

Behind the interface is a WebGL2 tunnel that reacts to the sound. Colour follows the selected sound, and the view can be steered with the mouse. On a phone the view is fixed.

## Why it exists

Background sound helps some people with some tasks and hurts others, so the tool asks what you are doing before it plays anything: deep focus, reading and writing, creative flow, routine, break and restore, or sleep. Rest is treated as part of the work. A timed session ends with a slow fade and a short arpeggio going down, then a silent break, then an arpeggio going up when it is time to come back. The author also built it as a working example of audio-reactive design that serves a practical purpose for people.

## How to use it

1. Open the site. A short welcome asks for a mode, a session length, your space and how you listen, then starts the sound.
2. Sessions: 25/5 (short sprints, the Pomodoro method), 50/10 (a longer block), 90/15 (one attention cycle), Custom (your own minutes of work and break) or no timer.
2a. Creative flow can add a ten minute warm-up before the first work block. It comes on top of the session length, applies to timed sessions only, keeps the same sound and ends without a signal.
3. While a session runs, a timeline shows one work-and-break cycle. Click or drag it to jump to any point.
4. Keyboard: Space plays and pauses, 1 to 6 choose presets, arrows change volume, H hides the interface and leaves the artwork and the timer, F goes full screen. Shortcuts work on a Russian keyboard layout too.

## What it is not

It is not a medical device or therapy and makes no health claims. Effects of background sound vary between people and tasks, and the evidence is mixed. The Research page lists the studies it draws on and what each one does and does not show. Volume guidance is an estimate.
