AudioTools from Studio Six Digital 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.

Actual reviews:

“...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.”

AudioTools - dB, Sound & Audio Positive Reviews

Fantastic, Best App I’ve Ever SeenThis is a solid reference tool. It has incredible features for acoustic analysis. I frequently use the SPL meter to quickly check levels; it’s far more likely I have my phone on me than a dedicated device. I have used the signal generators for testing speakers and the acoustic response of my studio. There’s everything you’ll want here (I don’t quite know what half the things do, but this app does it!). The only thing that will make this better is an omni reference mic since the built-in microphone has limitations, but as a ballpark quick reference (which is what I usually need), this is amazing. I recommend this constantly. The price is unbeatable. Considering buying one of each of the tools it has would rack up quite a bill, this app has everything and it’s all on your phone. Can’t say enough good things..Version: 11.9

Almost every tool you will ever needI have used this app for setting up sound systems (pinpointing feed back quick and easy), tuning speaker cabinets, mastering Cds. You will need more than this but its another tool. Few jobs can be done with just one tool. Yes to make some things easier you will need to purchase some additional tools. Still When a mechanic buys a tool box he generally adds more tools. No doubt your ears are your most important tools that you have, but this suit of apps are definitely a huge help. With this app you get a lot for 20 bucks. The additional modules make a complete tool box. With the ability to see what you hearing..Version: 10.20

Very good app and great serviceI initially rated this app low because it crashed on launch with my iPad Air 3. But the developer contacted me and asked me to try a beta version of the app that might solve the problem. The beta version worked great and they immediately released that version. Terrific customer service to resolve an issue. As for how the app works... I’m new to this so I’m still trying to figure out how to take measurements and how to use this information to make improvements to my home theater system. But the app seems to work well with the limited experience and knowledge I have at this point..Version: 14.5

Awesome appI’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..Version: 10.7

This is the oneWhether your novice, or your working class on a budget like myself. This app gives you flexibility to expand as your finance changes. With add on modules as low as 5 bucks on up you can’t go wrong. Buying some computer programs are expensive at the start up. Sometimes not with the features you want them to have. With this app, I can pick and choose when I desire to. And the pockets don’t get emptied. The best part of all has to be, the demo of the module you want to buy. This is so very useful to those unsure of its operation. Nice touch, very highly recommended to any one..Version: 14.5

By far the best.I’ve been using this suite of tools for five years. The app Always works, always does what I need and it is FAR less expensive than many other options. When I visit client sites it is so nice to grab samples and save as photos for later inclusion in reports. I do wish that there was a way — but I understand I can’t do it easily — to use a calibrated external microphone. However, at this price point that’s a big request. I highly recommend this group of apps for any user skills from beginner curiosity up to experienced audio engineers..Version: 10.19

Great app nice featuresI only use a small percentage of the app but it is great to have all of this in one place. Plan on getting then calibrated USB mic. Only current nit — don’t use the screen capture on IOS 11.0.2. If you need that try before you really need it or use the Apple supplied screen capture. On my device you loose most of the third octave bars and it totally clips the top of the graph. Hopefully when I upgrade to IOS 11.2 this will fix itself. If not, how the developers can research..Version: 10.9

Smaart and Transfer Function are GreatI have been using SMAART Live for years on my PC to do live sound. This is so much cheaper and works just as well for a really good RTA. I have the transfer function add on as well. It's very affordable for use by any working audio engineer. I have advised many touring pros to get this. I have now purchased 2 iAudiodevice2 for Smaart and Transfer Function and and I love them. I used to use the Shure mic Pre with a USB hub for power and it worked great too..Version: 10.8

Well worth it! Always updating.I just wanted to give my quick review..... features and functions and capabilities of the app are top notch. I don’t think there is anything that even comes close.... at least not that i have ever saw. My favorite thing is how often the app is updated and new modes, features, tests, and constant refinement happens. It obvious they care about the app and strive to be the best.... to me that means a lot!.Version: 10.18

Best I’ve foundUseful and so far as tested, very accurate. Learning curve is quick, even amateurs can use this. I do wish you could add “favorites” to the homepage of the app; I cannot be alone in that I use 3 of the tools most often, 1 occasionally and the rest not at all; would be great to access them with less click fatigue..Version: 15.4

Great app!!This is a professional level app. The quality is superb. If topiary only looking for RTA and/or FET, then yes, there are free apps that work just as good. However, Audio Tools offer different upgrades as your expertise increases. This way, as your skill level increases, you have the opportunity in purchase upgrades so all the apps you use will be in one location. That for me is a HUGH plus...Version: 14.3

Good StandardIf you were serious about measuring a quad to find the acoustic and audio in space this is the only app to buy. It is most compatible with useful accessories and produces reasonable output that you can easily share with your clients users..Version: 15.9

Best helpStudio Six Digital Audio Tools have been part of my arsenal for several years. From sound reinforcement projects to adjusting multi channel amplifiers, to test fire alarm notification appliance sound levels..Version: 15.5

I Use this great App DailyAs an Audio Professional, I use this App everyday in my work. I have have been at it fo 50 years. This App for about 5 years! I paid $35K for my first B&K 1/3 Octave Spectrum Analyzer which was the size of a 20” TV..Version: 14.10

It’s good but it feels outdatedIt’s not like the science or math has changed or needs to be updated super often, but the workflow and UI definitely feels outdated now in 2023. I like the SPL graph but it’s pretty janky to set up. In the SPL dashboard, I can’t tell any way to rearrange the different modules I have, or resize them take the amount of space I want them to take..Version: 16.9

Excellent tool set for audioI’ve had AudioTools for several years now and have added and updated as necessary. The tools are very useful, accurate and well maintained..Version: 10.9

Powerful but fugly interfacePretty obviously designed by an engineer that has no user interface designer friends. I am not an audio expert, and the interface sure doesn’t help me understand the importance of what each knob and button does. Some target values for different situations or examples of good and bad graphs and why, to use as a benchmark would go a long way for a rookie. I don’t blame the developer for my lack of knowledge, but at the same time, intuitiveness is a big part of the apps useability. As far as actual performance and features, its great..Version: 10.10

Has minor flawThe app doesn’t open properly on an iPad in portrait orientation when initially launched. Developer believes this is caused by bug introduced in iOS 13. If you open app in landscape, no problem. Or, after opening in portrait, swipe in from left edge to pull in the Audio Tools menu bar, then it works ok..Version: 11.8

A great valueI bought this kit and the Smaart plugin. The peak light on the 'analog' SPL meter doesnt light up on peaks, maybe the incandescent burned out, after all, its 50 years old. haha Please light peaks dull orange-yellow in an update. Hands down the best audio measurement app for iOS. Smith relentlessly expands development to improve features and support new hardware and OS..Version: 10.9

The original SPL meter is goneI want the old fashion spl with the blue background back. They just took it out of nowhere. Not cool when that is the one you have always used. Otherwise great app..Version: 10.13

Great Set Of ToolsBeen using this app for a few years now. I,ve checked it against SmaartLive, and it is pretty accurate..Version: 11.8

The best toolbox for live audio reinforcementIf you’re looking for an RTA, you can’t do better than the smart module in AudioTools. Do yourself a favor and get this app..Version: 16.2

Portable, professional Audio measurement and analysis tool box.The well thought out products included in the offerings from Studio Six are extremely helpful and capable..Version: 10.20

The Best professional audio calibration app out there!Light years above any other app. The most complete app based audio tool suite in existence. Worth every penny and a lot more..Version: 10.8

Good app that is regularly updated.New features and quality improvements come regularly..Version: 10.7

Trusty standbyExcellent choice if you are considering an audio utility for your phone. AudioTools has a lot of in-depth and crucial features, and they are always working on it. -1 star because it is difficult to restore purchases..Version: 10.11

Extremely useful and amazing app!!!Hello, I’m a music major at Berklee College of Music. I use this app extensively for one of my courses. It really delivers. I would like to thank the developers for the great app. Thanks, DM.Version: 10.8

Re registerOnly issue I have is every time I use it I have to re register the app or if there is an upgrade. Just a hassle. App works fine..Version: 15.0

Please support audiobusI want to use a parametric eq to tune some monitors to flat, but this is not possible to verify in LARSA because Audiotools won't let me run it through the same EQ. The easiest way to do this would be to add audiobus support to Audiotools/LARSA. Then the signal sweep can get corrected by the same EQ I apply to other apps..Version: 10.17

The ideal one stop shopEverything I need for day to day work and trouble shooting in my pocket..Version: 14.11

EDC for all working sound humansLeatherman? check. Flashlights? check. Sharpies? check. Gaff?check. AudioTools? check. Never leave home without it!.Version: 10.7

Better than a 4 starI am still working with the many modules I now have. If they all work as well as the ones l have tried.... this will earn a 5 star!.Version: 10.20

Regular userI’ve been using AudioTools for years. I rely on the FFT function to maintain listener comfort and clarity in my church on a regular basis..Version: 16.4

Best App for iOSTried literally every other app and nothing else compares..Version: 10.7

Decent app, but deceptive pricingFor potential purchasers - unlocking all features of the application will cost just a bit over $800. The $9.99 upfront app price is basically your crack dealer giving you the first hit for free..Version: 14.1

Thumbs Up30 plus years as a professional sound engineer, well versed in SMAART and TEF analysts. This is a very useful “On the Fly” APP!.Version: 10.15

OverpricedEverything useful is extra and this is already high for an app. Very very disappointed with what u get relative to other apps for the price.Version: 11.1

My to go appWorks every time and anytime.Version: 10.20

Excellent ApplicationGreat portable AudioTool Set. Keep up the good work Andrew ! Thanks Don.Version: 16.1

Very deep and well developed appI am an acoustics consultant and I have used this app on dozens of rooms as an impulse response measuring device. I know the app can be used for many other purposes and it looks like each one has been crafted with the same attention to detail to what I use it for. Also Andrew is very quick to respond to any issues or inquiries you may have with its functionality. Highly recommended!.Version: 15.9

The Analog SPL meter issue with iPhone 14 ProThis app is great to quickly measure sound levels. Ever since I upgraded to the iPhone 14 Pro, the Analog SPL meter… graphically… the range dial is soooo misaligned. It’s like the dial is moved out of alignment. Please look into this. Thank you..Version: 15.8

Smaart Tools crashes upon opening on this latest update. FIXED!It’s crashing on both iPhone and iPad. YOU FIXED IT VERY FAST WELL DONE!.Version: 15.4

Never stop learning about this appThis app carries enough feature to handling many complicated situation..Version: 14.6

Audio toolExcellent app for audio lovers.Version: 14.5

Works as promisedThe app works as promised after upgrading to latest version. Very good, highly recommended..Version: 14.5

Best toolkit!Use the RTA for room acoustic measurements, signal generator great for speaker testing, I have had this app for years, real problem solver..Version: 11.9

Expensive but works ok.Quite expensive for what you get, then you are asked to pay a lot more for each add-on. Regret purchase? Yesss!.Version: 14.1

Excellent Suite of Sound AppsAs a team lead for a House of Worship volunteer sound team, I use several of these apps with the team religiously :). Very useful and effective..Version: 11.3

20 dB differenceI compared the rta level with my iPhone se and the iPad is 20 dB louder. Why is the big difference?.Version: 10.8

Absolutely Fantastic!I setup a friend's stereo in his garage with this app. I got him to purchase it aswell once I showed him the RTA and DB Meter (he loved the app too since he is a professional musician and this app can help when he sets up for his gigs). But in his garage, the surfaces of everything was so hard that the sound was irritating! So we dialed in each frequency of the EQ (little 7 band). He hooked up his iPhone through the stereo and using the Signal Generator he set each frequency to the band of the EQ (the EQ was set completely flat for the baseline test). I went to the middle of the garage and measured the SPL with my iPhone. Once we knew the base SPL of each band of the eq, then he again applied the frequency's throught the stereo and we adjusted each band (one at a time) until the SPL was the same on each band. Now you can stand anywhere in the garage and it sounds fantastic. We adjusted the response of the system in the room and now is completely balanced and the clearity is unreal! There are no harsh tones and has fantastic stereo seperation. It worked so well there is only about .5dB loss from one end of the garage to the other. I'm currently looking for dual mono 30 band EQ's for myself just so I can fine tune my home audio system with this app. I have also used it to tune my bass guitar (adjusting the pickups) so the volume of each note is within about .5dB of each other. I have tuned car stereo's, setup for friends gig's, etc. If you're an audio nut, you will love this app! Keep up the great work guys!.Version: 0

FantasticAn amazing suite of tools. Super professional. I am demonstrating sound and audio measurement principles to my students in a technical theory course at University. I could lug all the big expensive gear in the room, shoot the meters with a video camera and project that onto the big screen, or...simply plug my iPad into the external VGA connection (with the VGA adaptor) and, voila! Real time analysis. I like that I can use the generator on my iPhone and display the results on the iPad. Keep up the excellent work, people!.Version: 3.5

The best app a capabilities. You can make a living with this if you know what you're doing.Fantastic app and the additional in-app purchases have been stunning! Five years ago this set of tools would have cost thousands of dollars AND you would have needed a vehicle to schlep it around - now an iPod Touch & a pencil bag for the mic and pre and your set. I'm amazed every time I use it - all this ability & accuracy in the palm of my hand... Cool. Andrew keep up the great work. I'll be downloading the STC in-app as soon as iTunes let's me. Looking forward to SII app. Last words... For those people that gave negative comments about spending 20 bucks and not being happy with it. You're ignorance and obvious lack of age is showing. Sonny, this app is way too big for you..Version: 3.5

Great app - got the audio interface box - very niceNice app.. would be nice if some basic things like the digital SPL meter and tone generator were included in the $20 purchase price.. The box itself is very nice, still have a bunch of testing to do, but so far, so good.Version: 0

H.blais b.scNice program. Keep up the good work guys..Version: 0

Nice foundation for audio toolsetThe apps are accurate. The Modular audio toolbox concept is very nice. I greatly look forward to the future Of this app, especially impulse response creation! Ignore unprofessional naysayers, this app is good. Keep up the good work..Version: 0

3D , WaterfallAwesome Ap !!! Wish it had a 3D FFT. FFT with 3'rd dimension bring time ..Version: 10.0

IPad proSmaart live is working perfectly and is killing it specially now that I can use the split screen on my iPad Pro!! Keep up the great work (maybe a favorite app fast access thing would be nice).Version: 7.9

Not much for $5The basic app will set you back $5. After that everything is extra and not inexpensive. Poor value..Version: 7.3

So so appThe tools are very useful. The recorder however is completely and utterly unreliable. I am unable to save the recordings and have now lost some critical audio recordings. If you want an audio recorder, is is NOT the app to use. It's ability to effectively save files is not there, I just lost a recording now again...so not impressed! Some of the other tools I like and are useful. Unfortunately as an all round fully functional app this doesn't quite capture it for me!.Version: 7.1

Amazing Tool BoxI am amazed at the capabilities in this package. Great support when I had a minor problem. Keep up the great work Andrew!.Version: 6.6

Great app!Being for the ipad it is very convenient and easy to use. Fast and easier than pulling out the old laptop. Using the internal mic of my iPad 3 it appears to be very accurate. Easily save graphs to compare later. Hopefully Andrew comes out with a waterfall graph soon. Using the FFT module to adjust and flatten out my sub as it has the 1/12 and lower octave measurement to eq my sub more precisely..Version: 6.4

Great set of tools!I use These apps with the iO interface 2 on my iPhone. I took time to compare various output data directly with my long time existing measurement system (EASERA, laptop and RME FFUC) and while a few of the calculations seem to not behave, most of the data is totally great. Studio 6 seems to be very busy improving the apps all the time and given the very low cost and exceptional convenience, I very highly recommend AudioTools and the interface! I may get the i test mic also. I use this gear professionally in my acoustical consultancy... Not on all projects but much of the time these days!.Version: 6.0

This app helps pay for my iPhone!It astounds me that I am able to conduct detailed site surveys, technically support what I hear or do - without bringing in the rather large tool box of specialized equipment. It's all in the app! And the extra purchases are also a fraction of what they would cost in the pro world. I like the fact that the app designer is also CTS certified as there are some criteria to truths we are committed to. So the promises for continual upgrade are undeniably real. My sincere thanks to those who have shared this valuable intellectual property. It has helped greatly..Version: 4.8
