REW-like app for mobile (Android/iOS)

This is my repaired KEF 105.3 with the Chinese tweeter diaphragm and a 6dB voltage divider to reduce the treble. No eq applied. About ten samples averaged.

The divider is a four ohm resistor in parallel with the tweeter, and a two ohm resistor in series to bring it back to four ohms seen by the amp.

Before:

I’m pretty impressed with the consistency of the curves below 500 Hz. Taken with a hand held iPhone 12 a couple months apart, with no attempt to replicate the mic positions.

Yep, this next in the roadmap for HouseCurve. I want to add a real time analyzer mode, which will make it possible to do MMM, live tuning, etc.

Have you considered adding a SPL and RTA section for live use? Would be cool to get SPL readings weighted over time laeq30 etc. as well as just a smoothed slow rta to see the general response in room. Sort of like an alternative to Smaart for iOS

Would be amazing if you could make an android app too, but I assume audio input is unreliable on android hence why no one else is really doing it either.

Does anyone know an app for android other than Audiotool that they like? That seems to be the one I keep coming across. I don't like subscriptions or IAP btw, just looking for a nice measurement app.

I wonder if anyone has experience with Sound Spectrum Pro. Looks like it may be a decent option.

Hey all,
[...]
- Room Acoustics Meter, by Dr. Johann Gauss (free, with in-app purchases). The name is likely a reference to REW. The screenshots look pretty legit, but it has no reviews yet. It was released in October 2021.

Regarding the Android Room Acoustics Meter app: it was measuring an increase past ~8KHz, that didn't match what I was hearing.

The Spectroid app, produced a curve that seemed correct (played a sweep for it from here).

Both are from listening position. Using a Pixel 8 Pro with the latest updates.

For completeness, Spectroid settings to get the reflections "soup" as Amir calls it:

Went to do some Housecurve measurements and couldn't connect via Airplay no matter what I tried. Then ran across a note on his website that IpadOS 18.4 broke it, but 18.5 fixed whatever it was. Connects fine again. Thought maybe this could prevent some aggravation for somebody
