HouseCurve is a tool for visually comparing the sound of your audio system to a reference curve.
HouseCurve was designed for tuning audio systems. For example, manually adjusting an equalizer in a home or car stereo.
HouseCurve works by playing a log sine sweep through your audio system and measuring the in-room frequency response. Multiple measurements may be averaged to fully capture how the system sounds in the listening area. Measurements are displayed on top of the reference curve, making it easy to determine how to adjust your system. By making small adjustments and repeating measurements, you can tune your system to the reference curve.
HouseCurve was designed to produce acceptable results with the iPhone / iPad microphone. For users wanting higher accuracy, HouseCurve also supports calibrated external microphones.
