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 *****

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.

Old outdated app. Ridiculous pricing

joerick on

Once you get in to this £20 app, you get a handful of very basic 'free' tools, the rest are paywalled behind extra ~£50 in app purchases. Scam. Avoid!

ribeye2134 on

Very useful. Essential iPad tool for sound professionals. Use it all the time. Particularly the SPL GRAPH for octave logging. Thank you very much

Taking a neighbour to court and using readings from SPL

Great product just very expensive

DanT man in van on

Great app just works out very expensive to get all the features

Jimrod76 on

This app WAS a really good tool for testing and measurements on the road but the latest update has rendered it useless on my iPhone 6. Bass levels are constantly showing high even when completely absent and high frequencies barely show. It seems some internal mic filtering is going on which can't be adjusted around despite resets or gain settings adjustment. Save your money until it's fixed.

File transfer?!?!?

Gingerpimp0069 on

Are you guys crazy!? The interface is clunky but acceptable, the mic seems ok but transferring and using any of the recordings plots or files - don't waste your time unless you want to waste a day chasing 'Terminal' based tips on extracting and using .bin files. Come on, solve the operating problems or can the app!!!

Great bit of software

Profile productions on

Yes it can be expensive, especially the smaart add on, but let's be honest everything in pro audio is expensive! Support is 100% updates are well thought out. And the developers are open to suggestions. Keep up the good work guys (just waiting for my imic to be delivered. The only thing I would like is a more reliable file transfer system, maybe to an external hard drive of some sorts? (That way I can leave it in a waterproof box monitoring for long periods of time)

Very impressed

True sound hire on

Very impressed from the start and over the last few months the updates have been a massive help. We use this tool / app pretty much on every job and the next step is to buy the audio tools mic kit with smarrt ! So thanks guys and please keep the work up :) From Tim and all the team @ www.truesoundhire.co.uk Faultless app :)
