Sound

A drone that sings in the key of the dream

There are two sounds in ADdes: a quiet drone of its own, grown from each dream, and your music, which it hears and never plays back. Either way, audio can only make the dream breathe, never strobe.

Two sounds

One it makes, one it hears

The built-in drone

A pure-Rust synth: detuned pads, sustained bell partials, pink “air” and an 8-line FDN reverb. Each dream's genome chooses its root, intervals and timbres, so every dream has its own voice.

  • It breathes with the picture, 6.5 times a minute.
  • By default it ducks to silence when other audio plays.
  • The screensaver stays silent.

Your music

Other apps' audio is captured with WASAPI process loopback that excludes ADdes itself, analysed in-house, and applied as slow, bounded tints. The dream hears your music, never itself.

  • It stays fully offline.
  • Every feel dances a little with music, at its own Audio reactivity.
  • Process loopback needs Windows build 20348 or newer.
Hear it

Hear the drone

Pick a mood and press Listen. Nothing plays until you press the button, and the sound arrives slowly.

The drone needs JavaScript and Web Audio, and one of them is off here. Everything else on this page reads without them.

Silent. Press Listen to begin.

The slider stops at the loudest setting the offline test checked.

Mood

Voice:

Root
Voicing
Voices

This is a web re-creation of the idea, not the app's synth. It follows the app's recipe for the root and the voicing, but the oscillators, filters and reverb here are your browser's, so it sounds related, not the same. It never uses your microphone, and it does not listen to your music.

Hold still pauses the picture only. The sound has its own Stop, always in view. A gentle limiter and a soft ceiling keep every peak under the app's own ceiling, -1 dBFS.

Eight ribbons: the drone's sound split into eight bands, low to high, as the app's own analyser does. They are coloured by the voice's palette, and they never move fast.

How a mood becomes a voice

  • In the app, the root walks the circle of fifths with the palette's mean hue, at 55–82 Hz (A1 up, folded down past 82 Hz to stay low and warm). The wheel shows where this voice's palette lands.
  • The voicing (up to six voices) depends on the palette's mood.
  • Bright moods (Dawn, Ember, Prism, Aurora) get open fifths, octave, ninth and a Lydian sharp eleventh.
  • Every other mood gets a dusk voicing, fifths with a minor third and minor seventh.
  • The voicing glides when the dream changes. Change the mood while it plays and listen.
  • On this page, the seed also chooses how many voices you hear and what each is made of. The same seed always gives the same voice.
The rule

Audio can only make the dream breathe

The music tints the dream; it doesn't drive it. Every reaction to your music lives inside these limits.

Slow in, slower outAudio-driven modulation has an attack of at least 250 ms and a release of at least 1.5 s.
ShallowDepth is capped at about ±10–15% of each parameter.
Never a flashBeats never trigger flashes or jumps.

The chart needs JavaScript. It draws a made-up 128 BPM beat as sharp spikes, and under it the dream's response as one slow swell that stays inside the cap.

A made-up 128 BPM beat drawn as sharp spikes, and below it the dream's response drawn as one slow swell that stays inside the cap.
The spikes are the music, at 128 BPM. The swell is all the dream is allowed to do about it: it rises no faster than the attack allows, falls no faster than the release allows, and never reaches the cap. The scale bars below the chart are drawn to the chart's own time axis, so you can see how slow the limits are beside one beat.

This chart is an illustration of the rule, not a recording. The beat is made up, and the curve is drawn through the rule's limits, not through the app's code. In the app, the rule is tested: the test track is a synthetic 128 BPM beat, the worst case, and at most 5% of the movement in any music-driven setting may be faster than 2 Hz.

When you travel

The drone opens as shapes pass

Between passes the drone is muffled (a low-pass near 580 Hz). As a shape passes you it opens wide: the filter opens, and the drone's own voices brighten.

Each shape also carries a soft whoosh of air that pans with it and drops in pitch as it goes by (a Doppler shift, exaggerated so it can be heard).

In a neon hallway the drone opens wide as you pass through each frame and closes between them, with a soft whoosh and a Doppler drop as the frame's rim passes around you.

Where the sound lives

The drone is set to When quiet by default: it plays on its own, and steps aside for your music.

What you won't hear

The screensaver is silent

Not every ADdes is for listening to.

ADdes as your Windows screensaver covers every monitor, silently, with no overlay. The screensaver stays silent (it could wake a sleeping house).

The Visualizer feel is a feel that reacts more strongly to music, still inside the Trance Budget: the light swells and dips with your music's phrasing, on top of the usual gentle tint; never faster than twice a second, so it breathes with the music rather than strobing to the beat.
