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”. “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.” ***** Included in the app price ***** * SPL Meter A faithful reproduction of a classic analog SPL meter. Includes A and C weighting, and Fast and Slow ANSI decay modes. All filters meet or exceed ANSI type 1. * RTA A 1/3 and octave band Real Time Analyzer. Includes touch-GUI range control, a cursor, max/min bars, and noise curve overlays. * FFT Detailed acoustic analysis, up to 32876 points. View full detail or smooth to 1/24, 1/6, 1/3 or octave. Includes cursor, scalable graphics, and peak tracking. * Polarity Speaker polarity checker. Route the test signal to a speaker, and read the polarity of the speaker on the screen. * CLF Viewer Show loudspeaker data, including plots for impedance, axial response, sensitivity, polar response, and 6dB coverage, and a 3D color balloon plot. * Delay Finder Measures the time it takes for a pulse to return from a speaker. * Generator Generates sine waves, square waves, white and pink noise. * Line Level Tests A line level measurement function and frequency counter. * Audio Scope A dual-channel audio oscilloscope that includes auto-triggering, variable gain and sweep rate, and storage of scope images. * Recorder A mono/stereo audio recorder with WAV and compressed formats and 8k-48k sample rate. Transfer files via WIFI. * File transfer of results via wifi to PC / Mac. * Audio Calculators ***** Optional modules available for purchase from within AudioTools ***** * Smaart® Tools - Single channel module. The power of Smaart® on a mobile platform. Includes RTA graphs to 1/48th octave and Spectrograph. Split-screen on iPad. * Transfer Function -- Requires 2-channel interface. Two-channel FFT-based measurement. Allows you to analyze sound system performance with music or pink noise as the signal source. * ETC Energy Time Curve. Plot decay of an impulse over time, and compute RT60 time. Internal or External trigger. * Impulse Response Record and analyze an impulse or sine sweep, compute octave and 1/3 octave ETC, T30, C50, C80, CT, Definition. Also shows FFT and Schroeder curve. * LARSA Fast and accurate sine-sweep measurement of loudspeakers and rooms. * SPL Pro Digital SPL meter with ANSI Slow, Fast, Peak, and Impulse mode, along with LEQ. Includes A and C weighting, and all 10 octave band filters. * SPL Graph Plot second-by-second SPL level for up to 24 hours, and optionally record the audio. Also, add the optional Octave Band Logging upgrade to elevate this tool to rival any professional logging SPL Meter. * SPL Traffic Light Monitor live sound levels SPL and Leq and see status in a simple green-yellow-red display. * STIPA Speech Intelligibility Meets the current NFPA code standards for testing evac systems and schools. * Speaker Distortion Measure THD+n of any driver. * THD+n (requires iAudioInterface) * Impedance Meter and Plot (requires iAudioInterface) * Phase Meter * Amplitude Sweep



  • I Use this great App Daily

    By ClaudeHill2
    As 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!
  • Thumbs Up

    By Deference
    30 plus years as a professional sound engineer, well versed in SMAART and TEF analysts. This is a very useful “On the Fly” APP!
  • Can’t Calibrate Mic

    By MyKart
    I can’t get to step 1 with Audio Tools. The setup will not import my mic’s calibration txt file and the app keeps hasseling me to review it so 0 stars would be preferable but 1 is as close as I can get to that rating. It’s just a sales platform not a useful app as-is. You have to buy the add-ons to get actual useful data from it.
  • Misleading money-grab

    By Bordesh
    Really wanted to like this app. I read about all these different tools it supports in the description, and decided to pull the trigger on the most expensive app purchase of my life. Twenty dollars. Turns out that this only gets you a couple of simple "tools", most of which are available for free through other apps. The kicker is that the useful tools can cost anywhere between 5 and TWO HUNDRED DOLLARS. Who do these guys think they are? It's absolutely insane. Not even those videogames with endless "microtransactions" are this much of a shameless money steal. When you pay twenty dollars for an app, it had better be good. It shouldn't just be a portal to dropping another absurd amount of money for basic functionality you would expect.
  • The original SPL meter is gone

    By fakegamefinder
    I 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.
  • Trusty standby

    By ReallyFled
    Excellent 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.
  • Great app

    By sxr71
    Great app. Gets the job done.
  • Amazing

    By Slavazvuk
    One of the best, and precise tool !
  • Powerful but fugly interface

    By pbassham
    Pretty 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.
  • A great value

    By ampsarus
    I 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.
