HouseCurve is a multi-tool for audio systems. Use it for room correction, adjusting equalizers, setting subwoofer phase, choosing crossovers and more.


* Sine sweep measurements
* Display magnitude, phase and group delay
* Compare measurements to target curve
* Create and edit target curves
* Generate room correction filters
* Export parametric EQ settings or impulse response
* Average and history display modes
* Measurement save and undo
* Use with built-in or external microphones
* Connect with AirPlay, Bluetooth, headphone jack (analog) or use externally played sweeps

HouseCurve measures in-room frequency response by listening to your audio system play a sine sweep. Measurements are displayed on top of a target curve, making it easy to see where adjustment is needed. Multiple measurements can be averaged to fully capture how the system sounds in the listening area. With small changes and repeat measurements, you can manually tune your system to the target curve. If your audio system has a parametric equalizer or convolution engine, HouseCurve can automatically generate filter settings to match the target curve.

HouseCurve can help with home and car audio system tuning, from system equalization and room correction to subwoofer time alignment and speaker placement. Visit for more information on how HouseCurve works and how to use it.

Free trial - visit and give the HouseCurve app clip a try.

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

What’s New

Version 4.2.0

* Choose which internal iPhone / iPad microphone is used for measurements.
* Internal microphone can be used even when an external input is detected. This is useful when connecting to USB devices (ex: DACs) that appear as input and output to the iPhone / iPad.
* Input status shows USB microphone names when available.
* Fixed issue where curve source editor would not properly scroll when keyboard was active.

A great tool for the right purpose

This is a great app. It helped me troubleshoot some issues with my Audyssey room calibration due to the proximity of my seating to the back wall, which was causing some reflection cancellations. It’s not “reference level” but it didn’t need to be for this purpose. The developer was quick to respond to my questions about hardware and measurement technique.
I have an iPhone 13 Pro and the mic is good enough to get the job done. If I spent the money on a UMIK I would be using REW instead, but this app was the right tool just to get some idea of what my room challenges are. I tried using it with an iPad Air 4th gen too, but it gave me very different responses than the iPhone, perhaps due to its large reflective shape. The iPad rolled off below 50 Hz and had an increasing amplitude response above 2 kHz. Since I don’t have a reference mic, I’m trusting the iPhone more as it matches what I expect Audyssey to have done in terms of corrections, and the ramping frequency response from the iPad seemed grossly wrong. It probably just needs its own mic compensation.
Lastly the free app clip is perfectly executed to get a feel for what it can do.

Should have watched the video guide

It took me 10 minutes to figure out that I need to connect my ipad to the speakers to play the measurement sine sound. After that is done, and load the new profile into Soundsource on my mac. The sound is so much better. Before this app, I used to EQ match pink noise using FabFilter Pro-Q, but this app produces a much better sounding profile.

I do have dbx driverack pa 2 with rta-m mic, but that is for my live pa system. I use this app for my desktop monitor instead.

Game changer

This is a great addition to Roon! Room correct any Roon zone with your iphone or ipad, and then create filters to be used for Roon room correction in the app.

I just used this to tune my main system and my desktop setup. The desktop filters made the speakers brand new again.

The other cool things is, even though Sonos has Trueplay tuning, you can still use this to tune things further. Since this does not do any positioning/delays/etc it makes the Sonos tune better for audio, but leaves the Trueplay tuning intact.

Roon is not cheap, but it is worth it for having room correction for all of your connected systems, forever, even as you updgrade your equipment over time. HouseCurve is a no brainer. Probably the most surpising finds for me in a long time.
