ROOM ACOUSTICS · iPHONE APP
SonarRoom
See how your room shapes your sound.
SonarRoom uses LiDAR and your speakers to scan a room, play test tones, and build a full 3D acoustic map — sweet spots, problem areas, and exactly what to fix. Same impulse-response techniques the pros use, from your iPhone.
Free to scan. Unlock results from $4.99, or go unlimited for $9.99/mo.

How It Works
Choose Your Speakers
Pick your layout — stereo, 2.1, 5.1, 7.1, Atmos, or custom. Play test tones from your phone, or export a multichannel WAV for full surround on your AVR. Use your iPhone mic or plug in a USB measurement mic.
One Walk Does It All
Hit start and walk the room. SonarRoom scans the geometry with LiDAR, plays sine sweeps, records the response, and tracks your position — all in a single pass. Watch coverage fill in live.
See Your Sound
In seconds, get a full 3D acoustic map. Find sweet spots, diagnose problems, and get prioritized fixes for treatment and EQ — explained in plain English, no acoustics degree required.

Features
Unified Scan & Measure
LiDAR room scanning and acoustic measurement in one walk — geometry, speaker positions, and hundreds of measurement points captured together.
3D Acoustic Heatmap
Interactive visualization with switchable metrics — overall quality, SPL, frequency flatness, RT60 reverb time, bass energy, and stereo balance. Tap any point to inspect.
Sweet Spot Finder
Ranks your best listening positions with gold, silver, and bronze badges, scored on frequency balance, imaging, reverb, and bass consistency.
Problem Detection
Finds standing waves, dead spots, flutter echoes, speaker-wall interference, and excessive reverb — with severity ratings and plain-English explanations.
Frequency Response & EQ
Full 20Hz–20kHz response at every point with coherence analysis. Exports parametric EQ profiles to miniDSP, Dirac, and REW.
Actionable Recommendations
Priority-ranked fixes with exact 3D placement — bass-trap corners with dimensions, subwoofer moves, treatment surfaces — each with predicted improvement.
