A spatial synthesizer you play in the browser

Into the Void builds a sound and places it in space. Shape a tone with wavetables, grains or a sample, then put it anywhere around your head: in front, behind, above, near or far. Send it on a path through the room, and let your gestures, a MIDI controller or your head movements reshape the sound and the space together. Put on headphones: the 3D effect is binaural.

What it does

Sound

  • Two wavetable oscillators with a key-frame table editor; imports Serum and Vital tables or any WAV
  • Granular engine and sampler (WAV, AIFF, FLAC, OGG)
  • Sub oscillator, noise, FM, ring modulation and sync
  • Low-pass, band-pass, high-pass, ladder, comb and formant filters
  • Six effect slots with 21 types: reverbs, shimmer, delays, tape, freeze, chorus, phaser, distortion and folding

Space

  • 3D: azimuth, elevation and distance, rendered binaurally with HRTF and adjustable head size
  • 4D: drawn trajectories, orbits and LFOs move sources and listener over time
  • 5D: MIDI, MIDI learn, OSC, head tracking and phone sensors change timbre and space at once
  • Room model with wall materials, early reflections and spatial echoes
  • Record stereo WAV or Ambisonics (1st and 3rd order AmbiX) for VR, games and Atmos workflows

Workflow

  • 150 cinematic factory presets in 12 categories, plus a community patch library
  • 16-slot modulation matrix and 8 macros, arpeggiator, poly, mono and legato with glide
  • Scales and microtuning, including Scala files
  • Undo/redo, A/B compare, randomizer and loudness metering (EBU R128)
  • Live cymatics: the sound draws its own standing-wave figures

Requirements

A current desktop or mobile browser with WebAssembly and AudioWorklet: Chrome, Edge, Firefox or Safari. Headphones for the binaural 3D sound. A MIDI controller is optional (Web MIDI works in Chrome and Edge). After the first visit the synth also works offline and can be installed as an app.

Questions

Is it free?

Yes, the browser version is free to play. No account is needed; signing in only adds saving and sharing patches in the library.

Why can't I hear anything?

Browsers block sound until you interact with the page. Press Start audio (or M), then play the on-screen keys, the computer keyboard (A–L) or a MIDI controller.

Does the 3D sound work on speakers?

The 3D effect is designed for headphones. On speakers, switch the output to Stereo for clean panning without binaural coloration.

Is there a plug-in for my DAW?

A VST3, AU and CLAP plug-in with the same engine and interface is in development. Join the early access list to hear first.
