AudioTools by Studio Six Digital

AudioTools Screenshots


AudioTools is a suite of professional-grade audio and acoustic analysis apps. Included in the price of this app is a basic collection of professional tools — SPL, RTA, Generator, Audio Scope, and Recorder, and the framework to add more sophisticated modules as you need them.

And now with iOS 5, measure up to 120 dB SPL on your iPhone.

Customize AudioTools for your needs by buying any of the additional optional modules, like FFT or Smaart Tools I, at any time right from your iPhone, iPod touch, or iPad.

New! AudioTools is now featured in an iPad business profile video!

Start with the basic AudioTools package, and upgrade as you need more capabilities.

Add 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 doesnt measure up to this app suite.
