*** iOS Microphones
We have analyzied every iOS device, including all of the iPads, all iPhones, and iPod touches, and have created microphone compensation files that are applied automatically. You can trust the results you are getting, often within just a few dB of a far more expensive analyzer.
Upgrade to our iTestMic or iAudioInterface2 to bring your system up to full professional specs.
*** Save and Recall Graphs
You can save and recall graphs, marked with the GPS location, date & time, and your comment, as well as store the image to your photo roll.
Export the data as an XLS formatted file to your computer for inclusion in reports or further analysis.
*** Max and Min Bars
You can also turn on resettable Max/Min bars (see image #4) to capture peaks. Double-tap to reset the bars.
*** Specifications and Devices
The internal iPhone mic has a noise floor near 30 dB, and if your are running iOS 6, clips around 120 dB.
*** Touch GUI
Fully interactive touch GUI features includes scroll up/down, pinch to zoom or compress the vertical dB scale, or swipe horizontally to get a cursor that reads out the exact dB level and frequency across the screen. To make the cursor disappear, swipe it off the graph to the left.
The landscape-mode display flips 180 degrees so that you can face the internal mic in either direction.
*** Overlay Curves
Also included are optional noise curve overlays, in NCB, RC, PNC, NC, X-Curve and NR mode. See picture #2 for an example. Use this feature to get a quick reading on the noise levels in a room. Also includes the cinema large-room X-curve overlay.
RTA can be fully calibrated, whether you are using it with the internal iOS microphone, or one of our professional test & measurement mic solutions. And, if you are using iTestMic, the mic calibration is transmitted directly to the app, so you are always calibrated.
*** RTA or FFT?
If you are wondering if you should download this app or our FFT app, check out our website, we have a page devoted to this topic.

What's New in Version 8.2
RTA, best Real Time Analyzer on iTunes store
-Updated to latest calibrations and upgrades
Still Drains Your Battery
I wish the author would make the battery-draining background mode optional.
The author continues to tweak many aspects of this app, but it still keeps running after you exit it which drains your battery.
Same thing again. The author obviously likes to drain your battery.
New do-dadhs, but it still drains your battery if you're not watching.
Still has no way to turn off -- much less to default off -- the battery-draining background operation. Despite many updates, this app hasn't had a favorable review since 2013.
Another update and the battery-draining background operation continues. I really can't understand why this can't be made optional with the default being off.
With each new update, I hope that they will finally remove (or at least make optional) the battery-draining background mode. But, this latest update is unchanged in this respect.
New iPhone 6. Latest everything. Still drains the battery by continuing to run after you exit the ap.
Well, they did it again. Another update and the battery burn continues.
What can I say? The battery drain continues in yet another update. No wonder this is no longer the most popular RTA in the Apple store. When will the author fix this?
Another update and the drain continues.
Another update retains the battery-draining background operating feature. When you exit this app, it keeps running and sucking your battery. You have to manually kill it. This single "feature" just ruins this otherwise excellent app for me.
Yet Another update and it is clear that the developer feels that this battery-draining background feature is somehow desirable.
I have given up. Obviously, they do not read these comments because we have yet another update and the background battery drain remains. They obviously like this "feature."
I've been a huge fan of this app for years. I consider it essential for live- sound work.
But, recently, they added this "background" mode in which the app keeps running even when you exit it. To stop it, you have to manually kill it... a big and inconvenient extra step. And if you forget to kill it, it will run down your battery. When you're mixing a show, you don't want this extra step.
This silly "feature" is a disaster. I have complained and complained and yet this "feature" persists.
There are other Real Time Analyzer apps. If you are looking for one, despite how good this app is, I suggest you look elsewhere because of this one overwhelming problem.
