INU

Turn any stereo track into a full Dolby Atmos bed — losslessly. INU upmixes to as much as 9.1.6, shows you exactly where the energy lands in a real-time 3D view, and folds back to binaural for headphone monitoring.

Stereo in. Atmos out. Nothing lost.

INU uses a lossless M/S ("nulling") upmix design, so the full surround output always recombines exactly to your original stereo. Push energy into the bed, wides and heights with confidence — the mix is always recoverable.

Lossless upmix

A nulling M/S architecture splits every input into Direct and Diffuse energy and places it across the field — while staying perfectly reversible to the source stereo.

Up to 9.1.6

Build the whole Dolby Atmos layout — bed, wide channels and heights — from 5.1.2 up to 9.1.6, driven by musical controls rather than routing spreadsheets.

Real-time 3D visualiser

A live OpenGL spatial energy view shows Direct and Diffuse energy as a smokey halo across the speaker field, with a moving centroid so you can read the balance at a glance.

Headtracked binaural

Fold the full field to binaural stereo in real time for headphone monitoring — with OSC headtracking, or emulate a tracker and drive the head from the spatial view.

Decorrelation

Multi-band all-pass decorrelation adds width and envelopment across the field without changing the spectral content — subtle or dramatic, always mono-compatible below your chosen cutoff.

Output routing matrix

A built-in patchbay lets you override however your DAW orders channels, solo any output, and fold C & LFE to dual-mono for stereo multi-out hosts.

Every format, on every platform

INU runs as AAX, VST3, AU, CLAP and LV2 in your DAW, plus a free Standalone app so you can audition the upmix and the spatial view without a session open — on Windows, macOS and Linux.
