File Formats

Aura Mixer reads and writes a few file types. You'll rarely touch most of them directly — but here's what each is for.

Aura Mixer files

ExtensionWhat it isHow it's used
.ngsaSession — your live mixer stateSaved automatically; you never open it by hand (see below).
.ngssScene — a snapshot of the whole mixerExport/import from the Scenes window to back up or share a full setup.
.ngspPreset — one processor's settingsExport/import from Workshop ▸ Installed (EQ, Gate, Comp, Limiter, Delay, Spatial, FX), or apply from each processor's PRESET ▾. Packs use the same format under the hood, also in the Workshop.

The session file

Your working state lives at:

%LOCALAPPDATA%\AuraMixer\session.ngsa

It's written automatically on every change — there's no "save" step. It's tied to your machine (it references your devices), so it's not meant for sharing; use scenes (.ngss) for that. Deleting the whole AuraMixer folder resets the app, exactly like a Factory Reset.

Exported presets are organised under Documents\Aura Mixer\presets\ by type.

Files Aura Mixer imports

Aura Mixer imports a few third-party formats:

FormatWhat it isWhere
HRIR .wav / .sofaA measured 3D-audio profile (an "ear print"); .sofa is the AES69 standard formatSpatial → HRTF, Model = Custom HRIR → IMPORT. (The Immersive model also ships ready-made measured profiles — no import needed.)
Equalizer APO config .txtAn Equalizer APO / AutoEQ filter config — its parametric Filter lines become a 12-band EQ presetWorkshop ▸ ImportEqualizer APO config. (The same menu also imports headphone-measurement .txt files as a correction or target curve.)
