Description
Autospread Box by Synthescience is a stereo imaging processor that widens mono and dual-mono signals into a spacious stereo field. It works by applying a subtle delay to one channel, inverting it, and introducing modulation to create a distinctive spatial spread.
The plugin is designed primarily for signals where the left and right channels are identical, such as unprocessed mono recordings or dual-mono sources. On these signals it produces a clear widening effect that adds dimension and presence.
When used on material that already has stereo differences between channels, the effect becomes more subtle. Toggling the plugin on and off reveals its impact even on complex stereo material, making it a useful tool for adding nuanced depth without overwhelming the original sound.
Users particularly praise its effectiveness on mono guitar tracks, snare drums, and vocals, where it creates a convincing pseudo-stereo spread. The plugin includes full automation support and 32 preset slots, with several factory presets included as starting points.
Autospread Box is a Windows-only 32-bit VST plugin (version 1.3, approximately 1.3 MB download). Installation involves copying the DLL files into your VstPlugins folder.

Frequently Asked Questions
What is the best stereo imager plugin?
The best stereo imager depends on your needs and budget. For a lightweight, no-cost option that works well on mono sources, Autospread Box delivers effective results through its delay-inversion-modulation approach. Paid alternatives like the Waves S1 Stereo Imager offer more advanced features including mid-side processing and bass-specific widening.
How do stereo widener plugins work?
Stereo widener plugins use various techniques to create the perception of a wider sound field. Autospread Box specifically applies a small delay to one channel, inverts it, and adds modulation. Other methods include mid-side processing, Haas effect delays, and frequency-dependent panning.
What is stereo spread used for?
Stereo spread is used to make mono or narrow-sounding elements feel wider and more present in a mix. Common applications include widening mono guitar recordings, adding spatial depth to vocals, making snare drums feel more expansive, and creating a sense of dimension on synth pads or backing tracks.
Does Autospread Box work on already-processed stereo material?
The plugin is optimized for signals where left and right channels are identical (dual-mono). On material that already has stereo differences, the effect becomes very subtle. It still works, but for the most noticeable results, apply it to unprocessed mono or dual-mono signals before other stereo effects in your chain.
