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. - **5★ · Almost every tool you will ever need · April 2, 2019** — I 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. - **5★ · Pro Audio Must Have App!! · May 22, 2026** — I work as a pro sound mixer and downloaded Audio Tools thinking it would be a cool toy to show off to collegues, but not much more. As it turns out, Audio Tools is a "how did I ever live without it?" app! I have used The RTA with the internal iphone mic to rough tune LOUD monitor wedges and FOH systems and so far have been very happy with the results. The db meter works great as does the tone generator. This app literally replaces $1000's worth of test equipment for the price of a Radio Shack db meter!! If you tour as an artist or band sound mixer and don't already have a SMART, Apogee, Earthworks rig, this app is for you, especially if you work on A different PA everyday! I can't wait to try the interface. ## About 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.
