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.”
