Description

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.” ***** 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 ***** * SoundScope VR - FFT-based audio analyzer with VR. The powerful acoustical analysis module. Includes RTA graphs to 1/48th octave and Spectrograph, and can display VR. * 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. * 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

    Smaart tools

    Started using smaart tools with the dual view as a lightweight alternative to using my full smaart rig. Very happy with the results and accuracy

  • ★★★★★Rockola54

    Great tool

    Thumbs up

  • ★★★★★Ricky-gene

    Simply the best

    Super accurate and easy to read modules. Best in the business!

  • ★★★★★Pgh Blues

    Great software

    This is a very nice software package I have been using it for years!

    Pro Audio Must Have App!!

    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.

    Re register

    Only 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.

  • ★★★★★AFCCPP

    Wonderful TOOL!!

    I use it often and it does the job for me and even rivals my $5000 analyzer🤔

  • ★★★★★Leaman Technologies

    Good Tools

    This is a great app for quick on the spot investigations. It has been helpful in demonstrating issues to non professionals. It’s great when you can explain it, listen to it and have a quick visual, without a bunch of gear.

    Ok

  • ★★★★★Einar Ristroph

    Fantastic

    I can’t say enough good things about this app collection. My fav is the augmented reality SPL Pro. As a noise control engineer, I can snap a picture of a noise problem and overlay noise level in a snap! (Only don’t snap while taking noise measurements.)
