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



  • 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.
  • Excellent tool set for audio

    By jeremyjo
    I’ve had AudioTools for several years now and have added and updated as necessary. The tools are very useful, accurate and well maintained.
  • Great app nice features

    By AStrand
    I 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.
  • The Best professional audio calibration app out there!

    By Saathoff1
    Light years above any other app. The most complete app based audio tool suite in existence. Worth every penny and a lot more.
  • Great App

    By Mac print
    Have been using this app for years. Sooo convenient to make in app purchases as my knowledge and experience improves
  • Mostly up sells

    By Newnqta
    Basics tools included the rest are expensive and not included. Disappointed for what I paid.
  • Extremely useful and amazing app!!!

    By Pan Monster :-((
    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
  • Smaart and Transfer Function are Great

    By John E K
    I 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.
