Slovox Multichannel Test Suite
Slovox
The Slovox Multichannel Test Suite is a free Reaper JSFX plug-in for testing multichannel and immersive loudspeaker systems. It sequentially cycles test signals (pink noise, sine sweeps, bursts) across a selected range of channels to verify loudspeaker layout, routing, and operation, used to check ambisonic arrays, beamforming speakers, higher-order Ambisonic domes, and other spatial setups ahead of installations and gigs.
History & Background
Developed by Slovox, the R&D lab of The Last Ear, a platform focused on attentive listening. The tool originated at the GoSpatial 2025 residency, where Slovox and Arconic merged independently developed test-tool drafts into a single JSFX. Runs inside the Reaper DAW. Distributed free via a "Friendware" model: the download is offered in exchange for contact about the user's setup and practice.
