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.

One of the best Audiophile Apps on iPhone!

Originally, I really had no clue what this app was but after one week in which I wanted to use REW to tune my Hi-Fi Rooms, I decided to give this app a try and after reading the guides on HouseCurve’s website, I setup tests through my main system, and after much tinkering with settings in both HouseCurve and Roon, I can happily confirm and report that this amazing app has helped my Hi-Fi system sound better than ever!!!!

Also if you’re annoyed about the $10 tuning payment, that’s all you have to pay, no more or less, and way cheaper than doing tuning with a measuring mic along with something like REW, and it’s a lot simpler to use HouseCurve anyways as well!!!

Seriously, give it a try, and I believe you won’t regret it.

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.
