Description

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

Features:

* Sine sweep measurements
* Display magnitude, phase and group delay
* Compare measurements to target curve
* Create and edit target curves
* Generate room correction filters (PEQ or FIR)
* Filters can be used with Roon, Volumio, miniDSP, EqualizerAPO, CamillaDSP and more
* 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 housecurve.com for more information on how HouseCurve works and how to use it.

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

The free version of HouseCurve can measure your audio system and display a magnitude plot (aka "frequency response"). Additional features, such as room correction filter generation, advanced measurement tools and target curve editing can be obtained via in-app purchases.

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.

Works great with WIIM amp over AirPlay

I was able to use an external Dayton OmniMic (USB mic) plugged into my iPhone USB-C port. Also could read in the OmniMic calibration file, which is a huge bonus. Generated a 10-stage parametric EQ and loaded into the WIIM app. I’ve got fairly high-end speakers so I focused the tuning on the low-end (bass). Sounds great!

Is there a way to use this over (wired) CarPlay? It seems to default to the crappy car mic since the USB-C port is in use, and it would be better to use the internal iPhone mic since it’s compensated.

Overall great app!!

Works but use with caution

Leap works. I mean it using the mic and our phones so I’m not sure how effective it will be, but I just downloaded it to play around well I can say he must be very careful with this app. Like me, if you have the volume on your phone and equipment up too high when it plays the sweep it blew 59K worth of Martin Logan speakers in my system. And homes so probably should have used a more professional mic, and definitely checked the volume levels. just thought I would throw this out there to others. This is not anything against the app. Other than they should probably put a warning, but more so people don’t play with the volume up too loud.

Developer Response ,

Thanks for the feedback, I really appreciate it! Version 5.1.2 now has a warning that pops up if the iPhone volume is high when a measurement is started. The quick start instructions also say to turn the volume down, but I get that not everyone is going to read them (https://housecurve.com/help), so the warning was a good idea, thanks!
