*** 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. Calibration is updated regularly, automatically, from our cloud-based calibration database.
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.
*** Calibration
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.

If you know what this is, BUY IT!
I'm a freakin' App junkie!
Extremely handy tool for the audio folks, an RTA in your pocket. iPhone is somewhat limiting at a mere 105dB max and noisefloor of 28dB on my phone but for most basic quick tweaks, this will do the job. Of course if you get a real mic, this app is priceless. So Nathan and Luke, stop reading this and buy it already :)

Great app, works well, real easy to use and easy to calibrate. If you are looking for an inexpensive RTA this has got to be the one.
Suprisingly accurate.

I was hesitant to buy this app, thinking there was no way it could be remotely accurate. But since it was ten bucks, I figured it must be somewhat professional. So, I bought it, played with it a little, and then tested it against my analysis rig. I use smaart v.6 with a sound devices usbpre and an audix tr40a mic. I set up my rig and tested this app against it and was blown away by the results! It's very accurate considering the hardware it uses, and is a great app to have as a pocket rta. It's not as accurate or in-depth as smaart, but it's handy and is less than 1/100th the cost of my setup (not including the computer required to use it.) Overall, a great product. I have since bought studio six's tone gen and polarity check and am pleased with them as well.
surprisingly useful tool

Others have already stated the strengths of this application. So I'll just restate how convenient it is to have it with me at all times. You never know when you might be called upon to ring out some stage monitors....

Great app so far. Does what it's says but I hoped it played music from my iphone and ran this app at the same time for $9.99
Good, but FFT is better (I guess)

I was at work (I'm a live sound engineer) and we were discussing speaker phase, when I said "They should make an app so you could test spkrs with iPhone." It didn't take long before I found all the Studio 6 products. I now have SpeakerPop, GEN, SPL, & RTA. They all work wonderfully. That said, I was a little disappointed to learn about FFT. It's not made too clear in the descriptions, but FFT is basically a more accurate & detailed version of RTA. I wish I'd bought FFT, since I want the most accurate thing availible. However, I'd already purchased RTA, & because of App Store rules, I can't trade it in towards FFT. If you're going to spend $10 on an app, you are probably going to use it for work like me, so splurge & get the $20 FFT. I am debating it, my main hangup is that I've already spent $10 on the RTA app.
Not worth ten bucks.

This does not work as well as I hoped. What a waste of ten bucks. I wishbthere was a lite version of this I could have tried first.
perfect for what it is

I am a pro audio engineer and this app has proven very handy for nailing feedback problems on live gigs and frankly has saved my butt a few times helping me quickly rough in a system eq while the band's set has already started.
Good app

I've been a professional sound man for 30+ years I've seen a lot of gadgets some work and some don't but if you need good ball park measurements this app is what you need. I've tested it against my DBX RTA, Signal Scope and Mac the Scope on my lap top and it's accurate if you calibrate it properly. It's a good app for spot checking a room before you set your system.
