See how your room shapes your sound
Get the best possible sound from any room.
Play test tones. Walk the room. Get a complete 3D acoustic map showing sweet spots, problem areas, and exactly what to fix — all from your iPhone.
Download on the App Store Free to scan. Unlock results from $4.99 or go unlimited for $9.99/mo. 🔒 Your data stays on your device. No accounts required.Select your speaker layout — stereo, 2.1, 5.1, 7.1, Atmos, or custom. Play test tones from your phone (stereo), or generate a multichannel WAV file to play on your AVR for full surround measurement. Plug in a USB measurement mic for pro-grade accuracy, or use your phone's built-in mic with automatic correction. Calibrate latency in seconds.
Hit start and walk the room. SonarRoom simultaneously scans your room with LiDAR, plays sine sweeps through your speakers (or listens while your AVR plays the exported WAV), records the response, and tracks your position — all in a single pass. Watch coverage fill in live.
In seconds, get a full 3D acoustic map of your room. Find sweet spots, diagnose problems, and get prioritized recommendations for treatment and EQ. The same impulse response techniques used by professional acoustic measurement systems — from your iPhone.
You know how the same speakers can sound amazing in one room and terrible in another — boomy bass in one spot, no bass in another, weird echoes? SonarRoom figures all of that out with just your iPhone. Walk around the room for a few minutes, and the app builds a 3D map showing how sound changes everywhere — where to sit, what's wrong, and exactly how to fix it.
No acoustics degree required. The app explains everything in plain English — what's wrong, where it is, and what to do about it.
Running a 2.1, 5.1, or Atmos system? SonarRoom maps bass distribution across your seating area, finds the best subwoofer position, and identifies which seats have the worst acoustic problems — so everyone gets great sound, not just the center seat.
If your mixes sound great in the studio but fall apart on other systems, the room is the problem. SonarRoom identifies the modes and reflections coloring your monitoring, finds the flattest position, and generates EQ correction profiles.
You've invested in great equipment — SonarRoom shows you exactly how much the room is limiting it. Find the ideal listening position, quantify problems, and get data-driven treatment recommendations to unlock your system's full potential.
You don't need to know anything about acoustics. Walk the room, and SonarRoom tells you in plain English where to sit, what's wrong, and what to do about it. Scores, heatmaps, and simple recommendations — no jargon required.
LiDAR room scanning and acoustic measurement happen simultaneously. One walk captures room geometry, speaker positions, and hundreds of measurement points. Play tones from your phone or use an exported multichannel WAV on your AVR for full surround coverage.
Interactive visualization with switchable metrics — overall quality, SPL (volume level), frequency flatness (how evenly sounds play back), RT60 (reverb time), bass energy, and stereo balance. Tap any point to inspect.
Ranks your top listening positions with gold, silver, and bronze badges. Scored on frequency balance, stereo imaging, reverb, and bass consistency.
Identifies standing waves, dead spots, flutter echoes, speaker-wall interference, and excessive reverb — with severity ratings, plain-English explanations, and visual overlays.
Full 20Hz–20kHz frequency response at every point with coherence analysis and confidence bands. Coherence-weighted parametric EQ profiles exportable to miniDSP, Dirac, and REW.
Priority-ranked suggestions with specific 3D placement data — exact corner positions for bass traps with dimensions, subwoofer relocation vectors, treatment surfaces — each linked to a detected problem with predicted improvement percentages.
Compare before and after measurements with side-by-side or overlay modes. See difference heatmaps and metric deltas to verify improvements.
Export measurement data as CSV, full analysis as JSON, impulse responses as WAV, multichannel test signals as WAV, or generate PDF reports. Share through the standard iOS share sheet.
Plug in a USB measurement mic (miniDSP UMIK-1, Dayton UMM-6, Behringer ECM8000, and more) for professional-grade accuracy. Import .cal or .frd calibration files, or use built-in generic profiles. Your iPhone mic works great too — with automatic per-device correction.

Frequency Response
SonarRoom uses the same impulse response techniques as professional acoustic measurement systems. Adaptive Wiener deconvolution with per-bin SNR-adaptive regularization extracts clean impulse responses even in noisy environments. Harmonic pre-echo rejection eliminates distortion artifacts. Multi-sweep coherent complex-domain averaging validates measurement reliability. Automatic latency calibration ensures accurate results. Supports USB measurement microphones with imported calibration files for professional-grade accuracy.
