Your speakers might be good. Your room might be the problem. Room Audio Balancer helps you assess and improve your home audio setup using your iPhone or iPad. Instead of guessing where speakers should go, you can scan your room, define your key listening spots, and get practical guidance to improve clarity, balance, and immersion. Whether you listen from the couch, your desk, the kitchen, or all three, Room Audio Balancer helps you understand how your space affects your sound. What it does • Scan your room to build a spatial understanding of the space • Mark key listening zones like sofa, desk, bed, or dining area • Review your current speaker setup and compare it against better placement options • Get clear recommendations for positioning, angle, spacing, and listening focus • Use AR guidance to refine placement in the real world • Improve balance, stereo imaging, and overall listening experience • Built for real homes Professional audio tuning is usually reserved for studios, venues, and high-end installs. Room Audio Balancer brings that thinking into everyday spaces, helping you get more from the speakers you already own. It is not about starting from scratch. It is about reviewing, understanding, and optimizing what is already in your room. Great for • Living rooms • Home offices • Bedroom setups • TV and movie spaces • Music listening zones • Multi-use rooms where sound changes by position Why use it? Because “good enough” speaker placement often leaves performance on the table. A small change in position can make dialogue clearer, bass tighter, and music more balanced. Room Audio Balancer helps you make those changes with confidence. Set up smarter. Listen better.
