Spadio IR Creator

Visual 3D acoustic studio. Sculpt custom spatial impulse responses, place baffle walls, simulate materials, and export 24/32-bit & AmbiX IRs.

“Design custom 3D acoustic environments visually and export pristine spatial impulse responses in seconds.”

About Spadio IR Creator

Spadio IR Creator is a visual 3D acoustic studio and Impulse Response (IR) generator. Design authentic acoustic spaces visually—from dry vocal booths and indie rock drum rooms to scoring stages, cathedrals, and outdoor fields. Place movable acoustic baffle walls & gobos with real-time reflection blocking, select physically modeled materials (concrete, glass, wood, acoustic foam), and position sound sources with intelligent stage surface elevation snapping. Audition in real time through the Binaural Listen Deck with 360° listener head rotation and hardware head tracking (Apple AirPods, Bluetooth, Webcam PiP). Export pristine 48kHz/24-bit Studio Master WAVs, 96kHz/32-bit Float, Legacy 44.1kHz, AmbiX Ambisonics (1st, 2nd, 3rd Order), and AES69 SOFA files directly into Spadio3D, Logic Pro Space Designer, Pro Tools, and REAPER, or render custom audio stems with simulated room acoustics offline.

Perfect For

Music producers, sound designers, mixing and mastering engineers, game audio designers, VR/AR developers, film composers

Problems This Solves

Capturing physical acoustic spaces requires traveling on-site with starter pistols, sine sweeps, and expensive multi-mic arrays

Conventional algorithmic reverbs sound synthetic and lack the authentic physical geometry and early reflection phase of real rooms

Existing acoustic CAD suites (EASE, Odeon, CATT) are prohibitively expensive, steep to learn, and lack instant real-time binaural auditioning

Producing multi-order Ambisonics and binaural spatial impulse responses for VR and games requires tedious multi-step conversions

Key Benefits

Frequently Asked
Questions

What is an Impulse Response (IR) and why do I need Spadio IR Creator?

An Impulse Response (IR) is the unique acoustic signature of a physical space, capturing how sound reflections bounce off walls, floors, and ceilings. Spadio IR Creator lets you visually sculpt custom 3D rooms, place baffle walls, assign physical materials, and generate custom IRs for convolution reverbs without renting a cathedral, stage, or acoustic lab.

Which DAWs and plugins are compatible with the exported IR files?

The exported WAV impulse responses are 100% standard 48 kHz / 24-bit or 96 kHz / 32-bit float stereo files, fully compatible with Spadio3D Aux Convolver, Apple Logic Pro Space Designer, Cockos REAPER ReaVerb, Avid Pro Tools, Audio Ease Altiverb, Waves IR-1, FL Studio Fruity Convolver, Ableton Live Hybrid Reverb, and hardware digital modelers like Kemper, Line 6 Helix, and Quad Cortex.

Can I export Ambisonics for VR and 360° video production?

Yes! Spadio IR Creator exports full-sphere B-format impulse responses in 1st Order (4 CH), 2nd Order (9 CH), and 3rd Order (16 CH) AmbiX ACN/SN3D format, as well as AES69 SOFA files for game engines (Unreal Engine, Unity) and spatial renderers.

How do acoustic baffle walls and gobos work in the simulation?

Baffle walls act as movable acoustic partitions anchored to the room floor. You can place them around vocalists or drums to block direct sound paths, simulate acoustic treatment booths, or create localized reflection barriers. You can freely resize them with Shift-drag and assign specific absorption materials.

What is the difference between Point Source and Calibrated Stereo Pair?

A Point Source emits omnidirectional acoustic energy spherically in all directions—ideal for solo instruments, vocalists, and foley. A Calibrated Stereo Pair models two studio monitors with adjustable stereo width (0.5m to 15m) and dynamic toe-in that automatically rotates the speakers towards the listener.

How does the real-time Binaural Listen Deck work?

The Listen Deck lets you audition dry reference audio (presets or custom audio files) processed through the simulated room acoustics in real time. You can use the 360° listener head rotation slider (-180° to +180°) or connect hardware head tracking (AirPods CoreMotion, Bluetooth headsets, or Webcam FaceMesh) with a live Picture-in-Picture preview.

What acoustic metrics does Spadio IR Creator calculate?

The engine uses backwards Schroeder integration to calculate standard ISO 3382 acoustic criteria: RT60 (reverberation decay time), EDT (Early Decay Time), T20, T30, C80 (Music Clarity), C50 (Speech Clarity), and D50 (Definition).

Can I render sample audio directly with the room reverb without opening a DAW?

Yes. With the Sample Audio Export feature, you can click 'Export Audio with Reverb' to run an offline convolution pass on the active audio preset or your imported custom track, rendering the room reflections and decay tail into a pristine 48kHz/24-bit WAV.

Can I import custom 3D CAD architecture models?

Yes. Spadio IR Creator supports importing custom 3D files in OBJ, GLTF, and FBX formats, allowing you to load real architectural blueprints, venues, or stage models and run spatial acoustic simulations directly inside the geometry.

Are my audio files and projects kept private?

Yes, 100%. All acoustic calculations, audio playback, and IR file generation happen locally on your computer. Your audio never gets uploaded to third-party servers.
