AudioTools is a suite of professional-grade audio and acoustic analysis apps. Included in the price of this app is a great collection of professional tools -- SPL, RTA, FFT, Speaker Polarity Test, Generator, Audio Scope, CLF Viewer, and Recorder, and the framework to add more powerful modules as you need them.
Customize AudioTools for your needs by buying any of the additional optional modules, like Smaart Tools I, SPL Graph, or Impulse Response, at any time right from your iOS device.
We test every iOS device and calibrate the microphone level and frequency response for the best results. We have the ability to turn off the Apple low frequency filters, and on many devices we can measure up to 120 dB SPL.
Add iTestMic, iPrecisionMic, or iAudioInterface2 for a complete professional audio and acoustic test and measurement platform.
“...AudioTools is a “how did I ever live without it” app”.
“I think this application is the best I EVER purchased.”
“I have used many thousands of dollars of complicated test equipment that doesn’t measure up to this app suite.”

Leatherman? check. Flashlights? check. Sharpies? check. Gaff?check. AudioTools? check. Never leave home without it!
I’ve used this app for years now and have not rated it but it has always been up in the 4-5 star range. Great updates and quick to fix any bugs. I thought I bought the SPL pro once but it never transferred to my newer devices. I could be wrong it was quite a while ago, but everything else has always transferred with all my new devices. I found that there is an option to restore purchases but I did have to click the SPL pro button first for the choice to restore to come up. Andrew did respond but I had already figured it out. Thanks for your help and quick response.
Awesome tool best app ever a must have for any sound engineer.
New features and quality improvements come regularly.
Tried literally every other app and nothing else compares.
The dials on my sound generator are wayyy out of line with the new OS11. I’m running an iPhone 7Plus and had absolutely no issues with the app until the “new and improved” OS came about. Why are people always fixing things that AIN’T BROKEN???😡
The price of the individual modules seems way too high, especially for what else is available in the App Store. On top of that, the SPL meter still doesn’t display properly in iOS 11.
THE acoustics software tool for iOS.
Great set of tools for audio! Highly recommend these.
This app along with the iAudio interface offers tens of thousands of dollars worth of testing and measuring ability in one small package. The impedance meter alone is worth the purchase price.

This is bring respect back to phone apps. With a calibrated mic, you have a pretty powerful toolset. Use this in my car to EQ out exaggerated frequencies. If yer a sound quality guy. Get this thing.
This is THE app to have if you are in the field of acoustics at all. Using Dayton imm-6, calibration file and an acoustical calibrator with this app, I'm within a dB (across the spectrum 1/3 octave) of my reference desktop measurement system which uses a calibrated Earthworks M30. No, the described setup is not lab grade, but it is good enough for the majority of use cases. Using the ipad camera connection kit, I run the art dual pre to a real measurement mic for results on par with desktop Smaart. Note that this app has an add on for Smaart that is $49.99. It is single channel only but has proven extremely valuable. Audio tools does have its own add on module for dual channel measurements if you have the need. The spl meter modules using the imm-6 is reliable to about 110dB; beyond that it would be better to use a connection kit, USB sound card and decent measurement mic. There are a ton of tools and calculators included. The add ins are expensive but the base set alone is worth the asking price if you are really in the field. Read their website and watch the videos to get an idea of what this app can do.
This app is an absolute must-have for any audio professional. Hands down the best app of its kind. The only reason it didn't get 5 stars is because of its UI. It's very windows 98 esque.. I'd like to see a more apealing interface. But as far as tools and functionality is concerned, five stars!
A little pricy for some components, but quite useful.
Sorry for the delay guys, back in the states now... ABSOLUTELY AWESOME "Sound tech - love it... Use it daily at gigs, theater, etc... Smaart apps are the bomb. Issues fixed, so 5 stars it is. Couldn't ask for a better app for the iPad. :)" So quick to fix issues as well... Brilliant.
I don't mix a gig without it sitting on my console anymore. Quick, at-a-glance reference for SPL and RTA. I've ot just scratched the surface of all this app can do. Many, many thank you's to the creators.
If you are a real audio guy this the biggest reason to buy an IPad. This has completed changed the way I work. Superb in all regards.
The app says it requires iOS 4.3+, but iTunes reports there's a problem when syncing. It says this app requires iOS 7. I'm using 6.1.2. I get a red indicator on the app store icon to update, but it says all apps are up to date. What's the problem?
A must have app for convenience and value for anyone in Pro Audio or the audio hobbyist. Updates are timely and when there is a problem, they are quick to correct. Truly amazing the versatility this product offers on an iOS device. 10 years ago these features required a dedicated PC and $$thousands.
As far as function goes its great for audio tools on a phone. I just updated to the new "more professional" look and I have to say its really cartoonish and unprofessional looking. I really don't get this push for icons and buttons that are flat and have no depth. To me it's visually unappealing. I will not be updating my other devices until they go back to a real professional looking interface.
