Spadio IR Creator 3D Acoustic Studio Interface
The Problem & The Transformation

Physical Acoustic Capture is Broken. We Rebuilt It in 3D.

Traditional impulse response capture forces you to travel on-site with sweep speakers, starter pistols, and fixed mic arrays. Spadio IR Creator brings unconstrained acoustic geometry to your workstation.

Traditional Workflow

Rigid & Prohibitively Expensive

Renting concert halls or cathedrals costs thousands. Once recorded, microphone placements, wall positions, and room geometry are permanently frozen. You cannot move a wall or change a surface material in post-production.

Spadio IR Creator

Infinite Physical Flexibility

Drag room dimensions, switch between 7 architectural shapes, drop in movable acoustic gobo panels, and test concrete, wood, or glass surfaces instantly. Audition immediately through headphones with real-time head tracking.

Social Proof

Trusted by Audio Professionals Worldwide

See how mixing engineers, composers, and game sound designers use Spadio IR Creator.

★★★★★

"Designing custom drum rooms with specific wood and glass reflection slap used to take hours of tweaking reverb parameters. With Spadio IR Creator, I visually moved a baffle wall, exported the WAV, and dropped it into REAPER ReaVerb. Total game changer."

★★★★★

"The 3rd order AmbiX export is essential for our VR title. We imported our game's 3D temple mesh, positioned the listener, and generated spatial IRs that match the visual architecture 100%."

★★★★★

"Being able to audition the acoustic space with AirPods head tracking before exporting saves immense time. The Schroeder RT60 metrics match physical acoustic measurements remarkably well."

Frequently Asked Questions

Everything You Need to Know

Clear answers to technical acoustic questions and DAW workflow integrations.

What is an Impulse Response (IR) and why do I need Spadio IR Creator?
An Impulse Response (IR) is the acoustic fingerprint of a room, capturing how sound reflections bounce off walls, floors, and ceilings. Spadio IR Creator lets you visually design custom 3D spaces, position baffle walls, assign physical materials, and synthesize realistic IRs for convolution reverbs without booking expensive acoustic recording facilities.
Which DAWs and convolution plugins are compatible with exported IRs?
The exported WAV files are standard 48 kHz / 24-bit and 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 guitar processors like Kemper and Quad Cortex.
Can I export Ambisonics B-format 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 audio renderers.
How do acoustic baffle walls and gobos work in the simulation?
Baffle walls act as movable acoustic partitions anchored to the floor plane. You can position them around performers to block direct sound paths, simulate acoustic isolation gobos, or build custom vocal booths, with real-time reflection ray blocking and Shift-drag sizing.
What is the difference between Point Source and Calibrated Stereo Pair?
A Point Source emits omnidirectional acoustic energy in all directions, ideal for solo instruments and vocalists. 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 toward the listener.
How does the real-time Binaural Listen Deck work?
The Listen Deck allows you to audition reference audio processed through the simulated room acoustics in real time. It features a 360° head rotation slider (-180° to +180°) and supports hardware head tracking with Apple AirPods, Bluetooth headsets, or Webcam FaceMesh with 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 including RT60 reverberation time, Early Decay Time (EDT), T20, T30, Music Clarity (C80), Speech Clarity (C50), and Definition (D50).
Can I render dry audio stems directly with the created room reverb?
Yes. With the Sample Audio Export feature, you can click 'Export Audio with Reverb' to perform an offline convolution pass on the active audio preset or your imported custom audio file, rendering the room reflections and decay tail into a 48kHz/24-bit WAV.
Can I import custom 3D architectural models?
Yes. Spadio IR Creator supports importing custom 3D architectural models in OBJ, GLTF, and FBX formats, allowing you to run spatial acoustic simulations directly inside realistic venue 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 leaves your device.
