Purpose and Core Concept

Spacelab is a single plugin that merges reverb, panning, and spatial audio into one cohesive tool, treating each audio source as an object in a virtual acoustic space. It is designed for music producers, film and video mixers, broadcast engineers, game audio designers, and VR/AR content creators who need to place sounds accurately within a three-dimensional sound field.

The plugin simplifies the workflow by eliminating complex routing typically required for spatial audio. Instead of managing separate reverbs and panners, you position audio objects directly within the plugin’s virtual room. This approach mirrors how humans naturally perceive sound in physical spaces, making the production process more intuitive and creative.

Key Capabilities

The high-end algorithmic reverb engine, developed with Fraunhofer IIS, delivers realistic room simulation from small rooms to large venues. Reverb time can be adjusted across nine frequency bands, and early reflections are generated uniquely for each object based on its position, updating continuously as the object moves through the space.

The object-based panner allows you to position audio around the listener inside the virtual room, record movements as automation via mouse, and view the entire arrangement in a 3D view. The listener can be freely positioned, and each source has individual dry/wet control. Up to twenty-four inputs and outputs are supported, with flexible speaker layouts up to many channels.

Workflow and Integration

Spacelab supports both classic send/return mode for traditional mixing and object mode for object-based mixing, fitting into existing production workflows. The plugin includes dynamic automation to simplify the management of many parameters, and a speaker layout editor lets you create custom configurations to match your monitoring or delivery needs.

To overcome DAW routing limitations, the Spacelab Beam plugin sends audio from any track directly into Spacelab, allowing flexible signal flow. The plugin works with Dolby Atmos and MPEG-H production workflows, and an optional MPEG-H exporter enables publishing in that format, such as for Sony 360RA when compatible conversion software is available.

Practical Applications

For music producers, Spacelab enables creating immersive mixes that translate across formats, from stereo to full 3D, without needing separate plugins for reverb and spatialization. You can place instruments around the listener, add realistic room reflections, and automate movements for dynamic soundscapes.

For post-production and games, the object-based approach supports precise placement of dialogue, effects, and ambience in a virtual environment. Binaural rendering allows monitoring and final delivery over headphones, making it suitable for headphone-based VR/AR experiences. The ability to mix once and output to any format—mono, stereo, surround, 3D, or binaural—saves time and ensures consistency across platforms.

Best for

Spacelab is best for producers and sound designers working in music, film, broadcast, games, or VR/AR who need a single tool to create immersive 3D audio mixes with realistic reverb, spatial panning, and binaural monitoring, especially when targeting multiple output formats from one session.
