HouseCurve is an iOS app for tuning home and car audio systems. Use it to adjust equalizers, set subwoofer phase, choose crossover frequencies and match levels.
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 will produce acceptable results with the built in iPhone/iPad microphone. Using calibrated external microphones will provide higher accuracy.
