## RTA Description
A Real Time Analyzer for the iPhone, iPad and iPod Touch. Test your speakers, tune your room, do acoustical analysis work or just have a better understanding of audio frequencies. RTA is a professional-grade acoustical analysis tool. All filters meet or exceed ANSI and IEC Class 1 specifications. 

Includes Octave and 1/3 Octave modes, with selectable decay times, as well as Peak Hold and true linear Average mode.

*** 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.

## RTA Reviews in Соединенные Штаты

### ***-- "Does not work on MQDY2LL/A iPad Pro with iTestMic 2"
The app keeps saying “Accessory found iTestMic 2” then “Accessory removed iTestMic 2” and repeats until the mic is removed from my iPad Pro. Sometimes it just crashes or freezes on my iPhone 12. Both have latest IOS.
-- l pazz, 2024-06-06

### ***** "Works!"
Simple to use and it provides all the info that I need.  Works fine on my iPhone 15 Pro.
-- Perpelxed, 2023-11-14

### ***** "Good tool"
I normally use smaart to tune but I’ve had this app for a long time and I still use it in a pinch.
I’ve checked out some of the other RTA apps and overall I have to say this one. Straightforward, no unnecessary bells and whistles. Highly likely built by someone who actually works in the industry
-- chsound, 2023-01-19

### ***** "The best iOS RTA"
Ignore all of the rest of them because this one is actually calibrated for your iOS device. I tried other apps setting up my vehicle and this one is obviously accurate. After about 10 minutes of tweaking the EQ on my head unit my new speakers sound 1 million times better. If you have a hard time setting your EQ to sound good this one will get you there.
-- Blake.is, 2021-09-06

### ****- "How accurate?"
How accurate is this compare to a calibrated measuring mic? My goal is to EQ my room to have a flat response. I have an iPhone XS Max.
-- starfall88, 2020-05-31

### *---- "Horrible"
I just purchased because I was referred to purchase it to help cal my room. Opened the app and the view only displays half of the app, please fix the view in OS 13.
-- DEJ9800, 2019-09-28

### ***** "Super RTA!!!"
I use this app at least 8 days a week! When the new iOS update came out the app was having problems fitting the screen. Everything still worked as expected, just smaller. I emailed the developer about the issue and had a response in 5 minutes! That is customer support if over seen it. In the response I was assured the new update is awaiting approval from Apple. Thanks Andrew for keeping us all afloat.
-- Thicks34, 2019-09-28

### ***-- "Has been great until now."
Not working properly with iOS 13.0 on iPhone XS.
-- MWW83, 2019-09-22

### ***-- "Was amazing"
Use to be the best RTA app out but have been having a lot of issues with it lately. Most recent problem is that the screen won't expand now.
-- Phewture, 2019-09-22

### *---- "Unusable in iOS 13."
App uses half the display after upgrading to iOS 13. Went to support page in the App Store and couldn’t find an email link to contact the creator. Disappointed...
-- lmauch626, 2019-09-22

### *---- "Fixed 1/3 octave analyser should be the name"
You cannot resolve anything less. And it is centered on 1 khz and not adjustable. Worthless for identifying frequencies and it's harmonics.
-- Zmistery, 2019-02-19

### ***** "JZ"
Just saved my bacon. Have a Trane Centravac chiller making a whine noise. This showed it is an 8k whine at the compressor.
 
Now I have some data to go back to Trane with.

I csn use this im my small audio room in my house now for some frequency readings.

Its worth the dough.
-- Jake Brew, 2018-08-27

### ***** "Fixed"
Wow! Fixed.  

It's nice to have such a good tool back working in a good way.

This really is a valuable tool for visualizing as you run live sound.

Thanks for fixing it.

----------

Same as before.  This app continues to run after you exit it and drains your battery.  I cannot understand why, update after update, the developer continues to cling to this "feature".  If you actually think that there is some use for this "feature", make it an option.  I shouldn't have to stop the app before I exit it; this is not the iPhone paradigm and, as a result, users are likely to forget to do it.  You hit home to exit the app, pocket your phone, and a few hours later discover this app still running and your battery low.

------------

Same problem.  This app continues to run after you exit the app and it drains your battery.

-----------

Same problem.

-----------

Yet another update that does not address the biggest -- well, only -- flaw in this app:  it still continues to run after you exit it which 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 operat
-- Gollnick, 2017-10-03

### ***** "Great app!"
Have been using it to tune rooms for small concerts, as a pink noise source and analyzer.  I keep it running during the show, and it really helps isolate feedback. Haven't had the battery issue that the other reviewer had, but I just make sure to exit the app when not using it.   

Great work!
-- Celloverp, 2015-12-30

### **--- "IPad, not so much"
Does not view properly on an iPad. Issues. Works great on my iPhone', but look for another solution on iPad.
-- Forester1962, 2014-05-20

### *---- "Doesn't work with iOS 7"
When will this work again? It was great with iOS 6 and before. All it does now is freeze when it is opened.
-- jdub00769, 2013-10-08

### ***** "Great, easy app!"
Title says it all - works well, easy to use and self-explanatory.  This should be on every sound engineer's phone!
-- Treeman5, 2013-09-26

### ***** "FOH Engineer"
Great tool for the money. I use this app for quick references during every live show.
-- Audio Professional, 2013-06-21

### ****- "Useful, but needs updates/configurability"
Great app!  I wish it was updated for newer products(iPad models, iPhone 5, etc.)
-- wigum, 2012-09-23
