SonarRoom Audio Analysis Tool vs Etherpad

Your room is changing the way your speakers sound — and you can't see it happening. Bass doubles in one corner and disappears in another. Echoes smear the stereo image. The couch might be in the worst possible spot. SonarRoom makes all of it visible. ONE WALK. COMPLETE PICTURE. Connect your iPhone to your speakers, tap Start, and walk around the room for 3–4 minutes. SonarRoom simultaneously scans your room with AR, plays test tones through your speakers, records the response, and tracks your position — capturing hundreds of measurement points in a single pass. SEE YOUR SOUND IN 3D When you stop, the app builds an interactive 3D acoustic map of your room. Switch between overall quality, bass energy, stereo balance, reverb time, and more. Tap any point to inspect its full acoustic profile. Rotate, zoom, and explore how sound changes from position to position. FIND THE SWEET SPOT SonarRoom evaluates every measured position and ranks the top listening spots — gold, silver, and bronze — scored on frequency balance, stereo imaging, reverb, and bass consistency. Stop guessing where to sit. KNOW EXACTLY WHAT'S WRONG The app automatically detects standing waves, null zones, flutter echoes, comb filtering, speaker-boundary interference, and stereo asymmetry. Each problem is named, explained in plain English, rated by severity, and shown in 3D — so you understand both what it is and where it is. KNOW EXACTLY WHAT TO FIX Every problem comes with prioritized, actionable recommendations: move speakers, add bass traps, apply EQ, reposition your listening spot. Each suggestion includes a predicted improvement percentage so you can focus on what matters most. PROFESSIONAL-GRADE ANALYSIS, NO EXPERTISE REQUIRED SonarRoom uses the same impulse response techniques as professional acoustic measurement systems — adaptive Wiener deconvolution, Schroeder RT60, ISO clarity indices — but presents everything through scores, heatmaps, and plain-language explanations. Temperature and humidity compensation adjusts for how air itself absorbs high-frequency sound, giving you accurate RT60 and reflection data regardless of room conditions. No acoustics degree needed.
