Spatial D320

Audiority's Spatial D320 is a faithful digital recreation of the Roland SDD-320 Dimension D, one of the most sonically distinctive spatial processors ever manufactured. Rather than simply emulating the hardware's fixed four-button interface, Audiority has reimagined the circuit for the plugin domain, offering continuous parameter control that transforms a somewhat limited utility tool into a genuinely expressive effect.

The core engine uses BBD-style chorus algorithms to create the signature thickening and widening character the original is known for. What set the SDD-320 apart was its particular warmth and organic spatial character - qualities that emerge from Audiority's inclusion of a 12AU7 valve stage that adds subtle coloration and harmonic complexity to the output. This valve modeling grounds the effect in the analog domain without overwhelming the source material.

Beyond nostalgic recreation, the plugin introduces practical enhancements: continuous Dimension control across all four modes, adjustable LFO drift rates, an ambience generator for deeper spatial treatment, and a focus highpass filter with intelligent mid/side routing. The integrated goniometer provides real-time visual feedback of stereo width, while the mid/side processor offers precision control over image positioning. These additions address limitations of the original without compromising its essential character.

Spatial D320 serves producers seeking vintage spatial enhancement with modern flexibility. It excels on vocals, strings, and synths where subtle widening matters, and remains useful across full mixes for cohesive enhancement. Among chorus-based spatial tools, it occupies a distinct middle ground between strict vintage emulation and contemporary, feature-heavy processors. The result feels less like a museum piece and more like an original design that happens to reference classic DNA.
