AudioTools Review

AudioTools from Studio Six Digital is a comprehensive suite of professional-grade audio and acoustic analysis apps. This app offers a wide range of professional tools, including SPL, RTA, FFT, Speaker Polarity Test, Generator, Audio Scope, CLF Viewer, and Recorder. Additionally, it provides the flexibility to add more powerful modules as per your specific needs.

One of the standout features of AudioTools is its ability to be customized with optional modules. These additional modules, such as Smaart Tools I, SPL Graph, or Impulse Response, can be purchased at any time directly from your iOS device.

AudioTools is designed to deliver the best results by meticulously testing and calibrating the microphone level and frequency response for every iOS device. Furthermore, it has the capability to disable the low-frequency filters on Apple devices, allowing for accurate measurements of up to 120 dB SPL on many devices.

To create a complete professional audio and acoustic test and measurement platform, you can complement AudioTools with iTestMic, iPrecisionMic, or iAudioInterface2.

Now let's take a closer look at some of the key features included in AudioTools:

1. SPL Meter: An accurate reproduction of a classic analog SPL meter. It provides A and C weighting options as well as Fast and Slow ANSI decay modes. All filters meet or exceed ANSI type 1 standards.
2. RTA: A Real Time Analyzer with 1/3 and octave band functionality. It features a touch-GUI range control, a cursor for precise analysis, max/min bars for easy comparisons, and overlays for noise curves.
3. FFT: Detailed acoustic analysis with up to 32876 points. You can choose to view the full detail or smooth the data to 1/24, 1/6, 1/3, or octave resolutions. The FFT module also includes a cursor for accurate measurements, scalable graphics, and peak tracking.
4. Polarity: A speaker polarity checker that allows you to determine the polarity of a speaker by routing the test signal and observing the results on the screen.
5. CLF Viewer: Provides comprehensive loudspeaker data, including plots for impedance, axial response, sensitivity, polar response, and 6 dB coverage. It even offers a visually engaging 3D color balloon plot.
6. Delay Finder: Measures the time it takes for a pulse to return from a speaker, providing valuable information about the speaker's performance.
7. Generator: Generates various kinds of test signals such as sine waves, square waves, white noise, and pink noise.
8. Line Level Tests: This module offers a line level measurement function and a frequency counter for added versatility.
9. Audio Scope: A powerful dual-channel audio oscilloscope that includes essential features like auto-triggering, variable gain and sweep rate control, and the ability to store scope images.
10. Recorder: A versatile mono/stereo audio recorder that supports both WAV and compressed formats, with sample rates ranging from 8 kHz to 48 kHz. File transfer can be done conveniently via Wi-Fi.
11. File Transfer: Easily transfer generated audio results to your PC or Mac via Wi-Fi for further analysis.
12. Audio Calculators: A handy collection of audio calculators for quick and easy calculations.

In addition to the robust features included in the base app, AudioTools offers a range of optional modules that can be purchased from within the app itself. Some noteworthy modules include Smaart® Tools, Transfer Function, ETC, Impulse Response, LARSA, SPL Pro, SPL Graph, STIPA Speech Intelligibility, Speaker Distortion, THD+n, Impedance Meter and Plot, and Phase Meter.

The reviews from actual users speak for themselves:

• "...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."
