AcousModules
AcousModules is a modular set of tools for acousmatic composition in high spatial resolution. The plug-ins focus on synthesis and effects and aren't limited to common spatial formats: most support up to 64 or 128 channels, depending on the plug-in, and can be freely arranged across peripheral, spherical, meshed or otherwise distributed speaker layouts rather than being tied to standard formats like Auro-3D or 22.2. The collection now spans roughly 192 individual plug-ins across spatialisation, effects, sampling, synthesis, utility and MIDI categories, including families such as the SpatStrument series and the smaller MiniTools collection for more targeted tasks. They're available in VST and AU formats, all distributed as freeware, and integrate easily into multichannel hosts such as Reaper, Ardour, Pyramix and Bidule that support free channel routing.

history
+–
AcousModules has been built since 2003 by its developer, known online as acousmod, using SynthEdit as the underlying plug-in-building environment, an approach the project has stuck with for over two decades. What began as individual spatialisation and effects modules grew steadily into the current library of around 192 plug-ins. After roughly four years of work, the whole series was brought up to modern 64-bit standards in 2022, moving to VST3 on Windows and AU on macOS, alongside a legacy 32-bit VST2 option. Newer additions like the SpatStrument series and MiniTools collection continue to extend the project's original aim: letting composers work with genuinely open, freely configurable speaker spaces rather than being confined to standard surround or immersive formats.
