## What is Mobile Tools by AudioControl?

Car audio analysis tools.

Now you can test your automobile sound system audio using a professionally-designed test and measurement app.

The free app includes ad-supported, limited-feature versions of our professional-quality SPL meter, RTA, FFT Analyzer, and Polarity Tester. Upgrade with the AudioControl SA4100i test and measurement microphone and everything is free! All of the modules are automatically unlocked as soon as you plug in the microphone.

You can also buy any of the modules as ad-free and full featured, even if you don't use our microphone.

Using just the built in iOS device microphone, you can test things like frequemcy response, speaker driver polarity, SPL level, and more.

Adjust your sound system equalizer by sending pink noise to your system, measuring the frequency response with the RTA (Real Time Analyzer) or the FFT Analyzer. Try to get the flattest response, with a slight (or huge!) low end boost.

### 5/5 — Works as it should!

*2023-04-05*

Used the RTA features to EQ my car and sounds a lot better now.

### 5/5 — Excellent for checking speaker wiring

*2023-02-08, version 4.1*

I used this to check a few speakers that I suspected had issues with being out of phase without pulling them out, and it was dead on.

### 1/5 — Currently broken - just crashes without opening (iOS 12.4)

*2019-08-16, version 2.4*

Will update if/when fixed

### 5/5 — It's now a pain to use!

*2019-02-14, version 2.2*

*The latest update appears the have corrected the issues. My review score has been updated to reflect that.*
After updating the app I periodically can not use the tone generator or other functions without connecting my SA-4140i SPL mic. The app prompts me to buy the additional functionality for various sums of money. I ALREADY BOUGHT THE $270 HARDWARE and do not appreciate being prompted to spend more money for functionally I have already paid for.

### 3/5 — Not Presently Compatible with IOS 12 (betas)

*2018-08-08, version 2.0*

Crashes immediately.  Downgraded to IOS11.4.1 worked fine.  Don’t waste your time on the betas; if you are using this software.
