AudioTools

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.

Actual reviews:

“...AudioTools is a “how did I ever live without it” app”.

Best audio App for iOS  macphoto77  5 star

Nothing else compares.

Worth The Money? (YES!)  alwaysmprest  5 star

I purchased v2.0 several years ago, and I've added modules as I need. (I've had years of amateur work in sound, and have no association w/ the developer: this is a Real Review of a remarkable, stable App.) This suite of sound measurement tools works very well, and replaces 2 cubic feet of gear that would cost about 10 times as much. You have to adapt to the tiny size of the control knobs if you use an iPhone rather than an iPad, but it's top notch. The limitation is if you have to do sound measurements for a legal procedure that requires calibration: talk to the developer: Andrew Smith is really helpful.) AudioTools is reasonably priced for the basic unit, but the in-app purchase add-ons can quickly add up quickly over $100 (still much less expensive than any normal pro tools). With that stated upfront, it's best to buy the basic kit for $19.99, and add tools as needed. Audiotools is a remarkably well-designed pro-grade set of audio tools. So far, (first on an iPhone 3G, a 5S, and now with a 7+, with the latest version of iOS 10.xx), it's reliable with repeatable readings, and has never crashed or frozen. It is adjusted for the frequency response of the internal mic, and a calibrated external mic is available, at a fair price (about $200, I think). If that sounds like a lot of money, look up high quality sound level meters So, if you need and/or can use this variety of tools (with frequent improvements), go for it. If you just need a good SPL meter, Studio Six Digital sells a stand-alone analog or digital meter that are nice (included in the full set, so don't buy lots of the separate tools if you think you will want the $19.99 set). The RTA (Real Time Analyzer) tool is a graph of SPL levels in each frequency band. Yes, it costs more than 99 cents, but it's a lot better and less expensive than any cheap apps I've used. I used the RTA yesterday to measure the noise frequencies from a new refrigerator, to design sound absorption. We are talking Cool AND Useful, (impresses friends and professionals, and lets you track down and correct those funny sounds from the music system, fridge, car, furnace, ducts, AC unit, etc. that make you crazy). This is the Real Deal, and inexpensive enough to design home or professional sound systems and sound absorption/ correction. This is really useful, if you are anyway into sound production or sound control, at any level of need, from a home owner looking to quiet a fridge or set up a music listening room, to any level of professional sound abatement or studio work. Separate pro devices may be a little easier to use (bigger knobs, etc.), but this group of tools is ALWAYS WITH YOU, as long as you carry your phone. If you discover you need the calibrated microphone, you can always do initial measurements with just your phone, to gauge the extent of the job, then go back for the mic.

I bought this app because a friend recommended it, I bought it and tried it, it worked for ten minutes then it froze and it never came back, I shut off my iPhone and powered it back up it still didn't work.

S Waugh

Great app!  S Waugh  5 star

I use this app for live sound, well done and easily worth the cost.

mordec25

The best application for sound treatment and analysis  mordec25  5 star

The best application for sound treatment and analysis for iOS. Professional grade. Better than the competition by far. Easy to use. Excellent price for the bundle.

TinenTech

Incredible value and quality  TinenTech  5 star

This is an incredibly handy suite of software, well put together, great attention to technical detail, and can solve all kinds of problems from adjusting the tone of PA systems to finding feedback and judging acoustics. The tone generator has almost everything you can imagine short of an impulse tick…and that’s included in the Delay Finder section. Even the included “Radio Shack” SPL meter is right on the money. Clearly, these guys know what they’re doing. I used to work with Audio Precision System One test sets, Audio Control RTAs, and Sound Technology testers, and if you had told me you could get this much power for this money and fit it in your pocket, I would have thought you were dreaming. Particularly nice they can bypass the high-pass filter in an iPhone 4S and adjust gain…too bad Apple isn’t letting them do that in the 6S, apparently.

Ygghigvfsv

Waste of $20  Ygghigvfsv  1 star

Don't get this app, it's a waste of money. Most of the content you still have to pay to get and the stuff that you do have access to is terrible to navigate through. This app seems like a 5 year old developed it, definitely not anyone with experience in the audio industry. Smh. COMPLETE WASTE OF TIME AND MONEY

Review of Audio Tools  Terry404  5 star

Been using this app for almost over a year and it is great when considering the value. I also purchased several of the in-app add-ons and each has worked great. Primarily use it for live and fixed sound system setup, but works very well at testing speaker drivers and boxes. Highly recommend AudioTools for your audio testing needs.

photofreq

Amazing app!  photofreq  5 star

Love the functionality and usability which this app offers. Hands down, the best tool on the iOS platform for audio professionals. Accurate (given the limitations of the onboard mic, external interface makes all the difference!) and detailed, great reports and relatively easy to figure out interface make it a great tool!

boldstandard

I'm not an engineer, but I love this app  boldstandard  5 star

When I bought this app over a year ago, it was pretty much the only one of its kind on the store. Now there are lots of competing ones, so I can't comment if this is the best or how it compares. I am a musician, and I use this app to gain a better grasp of the sounds around me. I quiz myself, guessing how many decibels a certain sound is, and checking my answer against the SPL meter, or trying to envision how the EQ is shaped when I listen to music, and checking it against the RTA. I use the pink noise generator with the RTA to get a flat sound from my PA when I am performing without a professional soundman. For all of these applications, this app has been an enormous asset. But the most helpful thing of all is in restoring my sanity-- about a year ago, I attended a very loud concert, and stupidly removed my ear plugs during the set. My ears were ringing for a few days, and I was afraid that I had given myself permanent tinnitus. Still hearing a faint high pitched noise at night in my bedroom a month later, I was convinced my hearing was done for. However, thanks to the RTA on this app, I was able to discover that there actually *is* a high pitched whine in my bedroom, and it's not coming from my ears. It turns out that the frequency which is spiking, around 20khz, twice the volume of the nearby background noise frequencies, is precisely the pitch that I had feared was tinnitus. You can't imagine my relief, and for that, this app certainly deserves my highest rating! Now, if I could only figure out what is actually causing that annoying sound in my bedroom..

libbyjo

More problems w/ 6.1.2 update  libbyjo  3 star

Had the app for about 9 months and the bugs seem to only get worse. Most annoying: cracks & pops passed to amp w/o the app even running, constant crashes, iaudiointerface 1 unable to sustain mic acceptance w/ iPhone. They seem to offer frequent updates but don't seem to correct the problems. Don't know if interface2 is any better.

Dougcs

Used to work great  Dougcs  2 star

After the latest update, my paid version now crashes when the paid FFT function is started. Can't recommend until this is fixed. Refund?

Soundguytyler

A total deception, don't waste your money like I did.  Soundguytyler  1 star

From the screen shot to the poor rta that come stock this thing is a ruse. I would not trust my reputation on either of the stock modules you get. They may claim you get this that and the other thing. What you essentially get is their "analog" spl meter the (digital version costs more), lol. The rta using the built in mic is laughable. He does throw in a decent calculator though. So to recap so far, the big three he offers for sale can easily be had for free in the app store. Another ploy he pulls is giving you a free module that will only work with an outboard piece of gear. The cost of those couldn't be determined as the page would not come up on the site. Pretty big red flag to me anyway. I don't mind paying for quality. I do quality work and get paid quality wages. I don't have have one sound system displayed on my web page and show up with something else, and then say oh, you didn't read the fine print. You don't get that with your purchase, I call that deception. What he is selling is a gadget. If you want to get what you think you are getting, you had better open up your wallet wide because it is going to cost you. In summery, there is NOTHING in the initial purchase that can't be found elsewhere for less or free. If you are the sort that has to have everything, an app addict if you will, then you have found a bottomless honey hole.

SPIRIT SOUNDZ

Very disappointed  SPIRIT SOUNDZ  1 star

Bought this app for over $19 and realized most of the tools were limited editions and had to pay extra bugs to get the others. Will certainly not try this one. Pls let the buyers be aware of what they're paying for. Very disappointed!!!

Paramneja Vu

Great app, for a price...  Paramneja Vu  5 star

I am a theatrical sound designer for theatre and live performances, and have been using this app for about a year now. It's had it's ups and down though the updates (With the recent iOS 6 update, it was a little screwy until studio six released an update of their own). Over all though, I find it to be an invaluable app. Between the calculators, recorder, and the Spectrograph, I use it all the time. The con, in app purchases are a must if you want real benefits from this app. The RTA spectrograph I use is a $50.00 purchase (in addition to the $10.00 you pay up front), but for my professional use, it's well worth it for me. Some of the built in features also tend to be over looked. The built in recorder is great quality, however the interface takes a little adapting, but I'm in it for quality. My favorite feature ha to be the way you can wireless transfer recorded files between your device and any computer on your LAN. When you utilize this feature, it automatically sets up your iPhone or Pad as a temporary online server, where files can both be downloaded and uploaded. It's simple, basic text navigation, but it works every time. You might have trouble getting it to work on complex networks (such as college campuses), but I've have great success with it. You simply type the IP address it tell you on your laptop/desktop on your web browser of choice, and you're connected! I use this app on my iPod paired with the Tascam iM2 dock condenser microphone (now $60). This means I now have a high quality, recording studio/audio diagnostic tool that fits in my pocket, quite literally. I would never use this microphone as a replacement proper recording, but when I need a vocal announcement for technical rehearsals 5 minutes ago? Or need to capture the sound of street traffic for a sound cue? This puppy has made it easy. Just record and wirelessly download to my laptop. My advice about buying, go to their website where all of the in-app prices are and decide for yourself what you actually need. I think if all you need is a great recorder, just buy the core app for $10.00 and you're done. If you need an RTA/Spectrograph or any of their other premium functions, be prepared to spend more. Five stars for being one of my tools of the trade.

LikeaBossMJ

Big disappointment  LikeaBossMJ  1 star

I purchased this app after reading all the feature lists and watching videos of its use. However, upon opening it up I discovered that the rta feature is limited to 1 octave and 1/3 octave. How am I supposed to get an acoustic environment reading with that? It's useless. Many of the features are blocked out unless you purchase them individually. WHAT?!?!?!? I paid $9.99 already and got nothing?!?!? The dock mic feature is supposed to enable the use of an exterior mic via the dock port. Doesn't work. It was picking up sound from the built in mic still. Don't waste $10 bucks of your earned money on trickery such as this app. You'll have to spend and additional $50 on in-app purchases to get the features listed in the description.

Smaart and other Tools Rock  John E K  5 star

I have been using SMAART Live for years on my PC for live sound and this is so much cheaper and works just as well for a really good RTA. I have not used it yet for transfer function, but assume it would rock if it is 1/2 as good as the RTA and other tools they have. It's affordable by any real working audio engineer and I have told many touring pros to get it. I use the Shure mic Pre with a USB hub for power as just got the iPhone / iPad Pre from the Audio Tools Website. It's is awesome.
