SonarRoom is the world's only room acoustics analyzer that builds a 3D heatmap of sound quality in your space — showing exactly where your audio shines, where bass drops out, and what to do to fix it. Most people don't realize their room is the biggest problem with their audio setup. Bass can be 20dB louder in one corner than another. Reflections cause echoes that blur your mix. Your listening position might be sitting in a null zone. SonarRoom makes all of that visible — then tells you exactly how to fix it in plain English. Key Features: 3D Acoustic Heatmap: The only app that maps sound quality across your entire room in three dimensions — not just a single point measurement. Plain-English Recommendations: No acoustics degree needed. SonarRoom tells you what's wrong and what to do. Full Walk-Around Measurement: Play a test tone, walk your room for 3–4 minutes, and get hundreds of data points mapped spatially across your space. Detects Real Problems: Identifies standing waves, bass null zones, flutter echo, comb filtering, stereo imbalance, and reflection issues. Sweet Spot Finder: Discover the best listening and mixing position in your room based on real acoustic data. Privacy-First by Design: All audio processing happens entirely on-device. No recordings are uploaded, no room data leaves your phone, no account required. Your space stays yours. No Special Gear Required: Works with any speaker system. Minimum iPhone XS running iOS 17+. LiDAR-enhanced mapping available on iPhone 12 Pro and later. Download SonarRoom and finally hear your speakers the way they were meant to sound!
