CULt Digital Signal Processing
CULT DSP builds open-source tools for spatial audio rendering, playback, and metadata workflows. Our research enables interoperability and interactivity. Our accessible tools are designed for artists, researchers, audio engineers, prototyping in immersive venues.
Realtime rendering and playback to arbitrary speaker layouts — built for studios, venues, and research environments.
Procedural spatial mixes and interactive scene data.
Guidance on speaker layouts, room strategy, workflow design, and deployment for installations, labs, and performance systems.
Transcoding pipelines for the future of NGA and spatial computing — moving ADM between tools, engines, and ecosystems.
Spatial Root
ADM transcoding and playback engine. Spatial Root plays Dolby Atmos and Sony 360 Reality Audio to any speaker layout in realtime. This tool allows for transcoding to between different immersive audio formats.
Spatial Seed
Procedural spatial upmixer that outputs ADM powered by machine learning. Generate immersive scenes for Spatial Root playback or ADM modification in a DAW.

Lightweight Universal Spatial Interaction Data — a scene metadata schema packaging spatial object positions, audio feature analysis, volumetric data, and agent state. Serves as the backbone to the CULT DSP toolchain.
by CULT DSP
Coordinates and Universal Localization Transcoding — a universal immersive audio transcoder that powers realtime decoding in Spatial Root and enables format interoperability across ADM, MPEG‑H, and NGA workflows.
