Description

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

Some calculations are wrong.

I REALKY WANTED THIS APP TO WORK TO SAVE ME TIME ANALYZING ROOM DESIGN. I CAN’T TRUST IT!! In room mode calc - for an example - this calculator is not consistent with most university calculators I can find through the series of frequencies you need to have to design room dimensions. Kind of difficult for me to put trust in this. As in most coding that’s heavy in multiple simple mathematical computations it is quite easy to make mistakes. I have bought a few of the sections from this company because some of them are handy and fast but I don’t trust ANY of the computations in this app because of the errors I have found. Ho to a good acoustical engineering college site - the european colleges are the best but you will have to convert to meters a lot but this is something that you can learn to do quickly with google calculator, even if you are a math dunce. It is probably going to be difficult for most people to analyze all these numbers in a full mathematical stat output but if you take your time you will - I hope - see the patterns. Just methodically look for numbers being close together. Acoustics are for math wizards, I guess, but it is a damned shame these people don’t really understand math and/or are sloppy coders. Is this app just another “money maker” for a sloppy coder?? There are far more sloppy coders than math wizard coders out there. Oh well, back to the spreadsheets. This IS ok for on-the-run pocket calculations but don’t trust it.

Developer Response ,

Hi,
Thanks for your feedback, we would like to connect with you to see where you are finding discrepancies. We work hard to get all of the modules to pass ISO Type One certification, but if there is something we have missed we will surely correct it. Please email us on support@studiosixdigital.com, as we can't get information from the reviews.
Best,
Andrew

Almost every tool you will ever need

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.

Awesome app

I’ve used this app for years now and have not rated it but it has always been up in the 4-5 star range. Great updates and quick to fix any bugs. I thought I bought the SPL pro once but it never transferred to my newer devices. I could be wrong it was quite a while ago, but everything else has always transferred with all my new devices. I found that there is an option to restore purchases but I did have to click the SPL pro button first for the choice to restore to come up.
Andrew did respond but I had already figured it out. Thanks for your help and quick response.

Hi,
Everything should come back with the Restore Purchases function, unless you had some in-apps that were bought from another App Store account.
