## AudioTools 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.”

## AudioTools Reviews in Canada

### ***** "Nothing less than stellar"
I bought this app many years ago and it’s still updated regularly. This app developer deserves a reward for not abandoning it like most do. 

Can’t praise this app enough, thank you so much. 

P.s… the fact you can buy Smaart in this is just crazy, limited yes but still amazing
-- N1N, 2024-08-18

### ***** "Well over 10 years"
And it’s still perfect.
-- SteveDougs, 2023-11-27

### ***** "Best pocket audio tools ever!"
This collection of audio analysis devices, are in use with me every day! I use them in the studio. I use them outdoors for noise complaints. They are accurate amazing devices.
-- Canterbury Music, 2023-03-26

### ***** "Excellent Application"
Great portable AudioTool Set. Keep up the good work Andrew ! Thanks Don
-- Comtec first, 2023-01-22

### ***** "Very deep and well developed app"
I am an acoustics consultant and I have used this app on dozens of rooms as an impulse response measuring device. I know the app can be used for many other purposes and it looks like each one has been crafted with the same attention to detail to what I use it for. Also Andrew is very quick to respond to any issues or inquiries you may have with its functionality. Highly recommended!
-- SSEll, 2022-11-30

### ***** "The Analog SPL meter issue with iPhone 14 Pro"
This app is great to quickly measure sound levels. Ever since I upgraded to the iPhone 14 Pro, the Analog SPL meter… graphically… the range dial is soooo misaligned. It’s like the dial is moved out of alignment. Please look into this. Thank you.
-- FTech, 2022-10-20

### ***** "Smaart Tools crashes upon opening on this latest update. FIXED!"
It’s crashing on both iPhone and iPad.
YOU FIXED IT VERY FAST
WELL DONE!
-- 666Corey, 2022-03-21

### ***** "Never stop learning about this app"
This app carries enough feature to handling many complicated situation.
