Soundtoys SpaceBlender
Soundtoys · $99
Soundtoys SpaceBlender is an experimental reverb for imaginary spaces, with X/Y envelope shaping, spectral color evolution, and tails up to 60 seconds.
A creative space designer more than a utility room reverb—best when you want nonlinear blooms, freezes, and spectral motion on vocals, synths, or sound design.
Best for: Producers and sound designers who need evolving, non-realistic spaces rather than accurate halls and plates.
Pros
- X/Y visualizer morphs gate, reverse, decay, and bloom envelopes in real time
- Color control can brighten or darken the reverb over time
- Time range from 100 ms bursts to 60-second ambient tails with tempo sync
- Freeze for evolving ambient loops; included in Soundtoys 5
Cons
- Not a replacement for natural room/plate tools like Pro-R 2 or Valhalla Room
- Experimental character can be too weird for transparent mix reverb duties
- Intro free window ended; full price is $99 standalone
Overview
SpaceBlender is Soundtoys' experimental reverb for spaces that do not exist in architecture catalogs. The company frames it as an imaginary space machine: spectral processing, nonlinear envelopes, and extreme time ranges that turn short sources into cinematic blooms or sparse swarming repeats. It sits in the same creative lane as Blackhole and Supermassive more than a utility plate.
It excels at playable space design. The X/Y pad reshapes the reverb envelope live between gate, reverse, decay, and bloom behaviors while a visualizer shows the shape. Color tilts the spectral evolution darker or brighter over time—something conventional reverbs rarely offer so directly. Texture morphs density, Mod adds internal motion, and Freeze recirculates the output into evolving ambient loops. Time stretches from tight 100 ms effects to minute-long tails with optional tempo sync.
The trade-off is purpose. If you need a natural vocal room or mix-bus plate, Pro-R 2 or SuperPlate will be cleaner daily drivers. SpaceBlender's character can dominate a dry mix if you treat it like a utility send. After the free intro period, $99 standalone is fair for a Soundtoys one-off, but Soundtoys 5 owners already have it in the bundle.
Choose SpaceBlender for ambient design, nonlinear FX, and sound-design tails. Choose Blackhole or Valhalla Supermassive for other huge creative spaces, and Pro-R 2 when realism is the goal. Our SpaceBlender announcement post covers the original free release context.
