OpenSpatialDelay is a free spatial delay plugin that places each echo at an independent position around the listener.
Released in 2026 by Andrew Rahman and Spatial Media Lab, it goes far beyond conventional stereo ping-pong delay. Producers can move up to 12 delay taps through a three-dimensional space, creating binaural effects for headphones, animated stereo textures and immersive mixes for film, VR or Dolby Atmos production.
A Delay Designed for Three-Dimensional Space
OpenSpatialDelay provides 12 independent delay taps. Each repeat can have its own azimuth, elevation, distance, pitch, Doppler effect and movement trajectory.
Instead of sending echoes only from left to right, the plugin can position them above, behind or around the listener. This makes it useful for atmospheric music, cinematic sound design, ambient production and experimental electronic tracks.
Main Features
- 12 independently positioned delay taps
- 13 animated movement trajectories
- Six binaural rendering profiles
- Seven spatialization algorithms
- Pitch shifting for individual delay taps
- Tempo-synchronized or free delay times
- Feedback filtering and modulation
- 70 factory presets
- Stereo, binaural, surround and Ambisonics output
Useful Even for Stereo Production
OpenSpatialDelay is not limited to professional immersive mixing rooms. Producers working with headphones or standard stereo monitors can use its binaural and stereo modes immediately.
The plugin can create wide rhythmic delays, moving vocal effects, atmospheric guitar echoes and evolving synth textures. Several factory presets provide accessible starting points without requiring detailed knowledge of spatial audio.
Animated Delay Trajectories
Each delay tap can follow a predefined path such as an orbit, spiral, figure-eight, helix or random movement.
These trajectories introduce continuous spatial motion without requiring complex DAW automation. Doppler processing can also change the perceived pitch as an echo moves closer to or farther from the listener.
OpenSpatialDelay Video Demo
Headphones are recommended for the official demonstration because the video uses binaural rendering to reproduce the movement of the delay taps around the listener.
Best Uses
- Ambient pads and evolving textures

Final Verdict
OpenSpatialDelay is one of the most original free delay plugins released in 2026.
Its 12 spatial taps, animated trajectories and binaural rendering make it a strong creative tool for producers who want more than another conventional stereo echo.
It can be used for subtle width or for sounds that travel enthusiastically around the listener’s head. Either way, the delay has finally discovered there is more to life than left and right.
