CULT DSP Projects
Free tools for playing and transcoding Atmos, 360RA, and other immersive audio formats. These projects provide scaffolding for future research into spatial computing and audio interoperability.
by CULT DSP
ADM transcoding and playback engine. Spatial Root plays Dolby Atmos and Sony 360 Reality Audio to any speaker layout in realtime.
Formerly known as sonoPleth. Built for researchers, spatial audio engineers, and composers who need layout‑agnostic immersive playback and clean, transparent ADM workflows.
● In Development
by CULT DSP
Procedural spatial upmixer that outputs ADM. Generate scenes that can be played back with Spatial Root or opened in a DAW for modification.
Built for rapid prototyping of immersive scenes and exploration of spatial “environment styles” while staying inside an editable ADM workflow.
● Early Research
by CULT DSP
Lightweight Universal Spatial Interaction Data — scene metadata schema that packages spatial object positions, audio feature analysis, volumetric data, and agent state. Serves as the backbone to the CULT DSP toolchain.
● Beta
by CULT DSP
Universal Immersive Audio transcoder. Powers realtime decoding in Spatial Root and provides format decoding/encoding and interoperability across ADM, MPEG‑H, and NGA.
