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. For more information on using HouseCurve, visit

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

Useful tool

For anyone owning a graphic equalizer, this is a great resource for tweaking your system to compensate for changes to your system or room acoustics. For example I rearranged an upholstered sofa and it really threw off my upper frequency response. I had an odd hole at around 125hz that I have now adjusted with the equalizer. Love this app!

Great and simple

Used this to tune my newly installed speakers and crossovers in my car using just my iPhone, and within 5 minutes I was in audio nirvana. Money well spent.
