How does HouseCurve work?

HouseCurve measures in-room frequency response by listening to your audio system play a sine sweep. Measurements are displayed on top of the reference curve, making it easy to see where your system needs adjustment. Multiple measurements are averaged to fully capture how the system sounds in the listening area. With small changes and repeat measurements, you can tune your system to the reference curve.

HouseCurve can help with home and car audio system tuning, from speaker placement and equalizer settings to subwoofer time alignment and room treatments.

HouseCurve will produce acceptable results with the built in iPhone/iPad microphone. Using calibrated external microphones will provide higher accuracy.
