CULt Digital Signal Processing

Immersive
audio tools

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.

What we build

Spatial Rendering & Playback

Realtime rendering and playback to arbitrary speaker layouts — built for studios, venues, and research environments.

Interactive Spatial Mixes

Procedural spatial mixes and interactive scene data.

Immersive Consulting

Guidance on speaker layouts, room strategy, workflow design, and deployment for installations, labs, and performance systems.

Metadata Transcoding

Transcoding pipelines for the future of NGA and spatial computing — moving ADM between tools, engines, and ecosystems.

Featured Projects

Spatial Root

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.

Research Audio Engine C++ ADM MPEG-H IAMF

Spatial Seed

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.

Research MIR C++ Upmixing Generative spatial computing

LUSID

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.

Cult
Transcoder

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.

Utility Interoperability ADM MPEG-H NGA
