Tools and Helpers


Overview

AudioTools has a rich set of support features in the app and companion apps that add functionality and build out the platform so that it is suitable for many real-world use cases.

Look through the list below, and you will see that we have the tools you need to make AudioTools your go-to test and measurement platform.

Saving Data, Exporting, and Importing

AudioTools includes a versatile and powerful system for saving and recalling test data and audio files, exporting them to a computer, and importing them into AudioTools running on another iOS device.

This feature is available throughout the app, in any module that saves a graph, and also in SPL Pro and STIPA.

Some modules can also save audio files. …

Moving data files between iOS devices

AudioTools stores data internally in a binary format, for displaying graphs. These files are not the same as the tab-delimited XLS files that are exported from the app to your computer. It is possible to transfer the binary files from one iOS device to another.

If you are storing files internally on the iOS device, use these steps to move a data file from one copy of AudioTools to another one on a different iOS device. 

Save to Photo Roll

AudioTools supports saving graphs to the iOS device photo roll. Look for the camera shutter icon, which appears on all pages that support the save to photo roll function.

The image will be saved minus all of the controls, to provide you with a clean image for adding to a report. After you tap the button and save the image, check your photo roll for the saved graphs.


Calibration

All of our apps come pre-calibrated for the typical iPhone built-in and headset mic, but you can adjust the calibration if you have access to a professional, calibrated meter to compare it to.

See our Microphones and iOS Devices page for more microphone information.

If you are using iAudioInterface2, see this page.

Also, in AudioTools, you can apply a microphone calibration correction file, by

Using Microphone Calibration Files

Beginning with AudioTools v4.1, you can import a file containing frequency response data for a microphone, and that response curve will be applied to the microphone in many AudioTools modules.

The microphone response correction data will be applied in all modules that display frequency dependent information: RTA, FFT, Smaart Tools I Single Channel, and Transfer Function. …

iCloud Support

New! Now available in AudioTools 7.9 or later, Apple iCloud is fully supported. Some of the features include:

  • All files are now stored on iCloud, if enabled. This includes internal as well as public files such as the tab-delimited output files, audio files, image files, and text files.
  • All files are stored under the "studiosixdigital" icon in iCloud.

File Migration Steps

Here are the File Migration Steps, and what types of files are copied in each step. Public files will include audio and video files, which for some modules (Impulse Response, Recorder, SPL Graph) are required by the app. All internal files are required by the app for each module.

  • Step 0: RTA public files    
  • Step 1: RTA internal files                    

Using Audio Files as Input Source

This document describes how to use audio wave files as the data source for audio processing functions.

Audio Files

AudioTools modules normally take their input from a live input source, such as the built-in microphone or one of the external options, such as iTestMiciPrecisionMic, or iAudioInterface2. Starting with AudioTools 9.4, you can now use a wave file for input, for some modules. 

Dropbox Support

Note: We now recomend using Apple iCloud instead of Dropbox. We will continue to support Dropbox until they cancel support for the API that we are using. Please not that at some point Dropbox support will be removed from our apps.

AudioTools now fully supports Dropbox. Get a free Dropbox account, link to it in AudioTools, and your saved files automatically sync to your Dropbox folder.

If you are connected to the internet when you save the file, it transfers immediately, and if not, your saved files will transfer to Dropbox as soon as you have an internet connection and open AudioTools.


Reference Curves

The Reference Curves package is an option in AudioTools that allows you to compare a stored plot to the live plot, generate an EQ curve, or set a +/- dB limit to test the live curve against. You can create the reference plot in a text editor, or from a saved AudioTools test. Reference Curves are available in RTA, FFT, Impulse Response, Smaart, and Transfer Function.

Color Picker

Use the Color Picker to choose your own colors for the plots in AudioTools.   

In FFT, Smaart Tools, Amplitude Sweep, and Transfer Function, you can recall multiple plot traces and view them at the same time on the screen. We have selected a palette of colors that we think work well, but you may want to change the default colors to your own selections.

Scheduler

Scheduler is a powerful upgrade that allows you to create a test schedule that includes a number of audio and acoustic measurements, that run sequentially, automatically.

You can control the length of time that each task runs, whether the generator is turned on, how long to wait between tasks, or whether each task is started manually.

AudioTools Wireless

AudioTools Wireless is an app that acts as a wireless transmitter to send the microphone audio to AudioTools running on another iOS device, using the local LAN. It also functions as a remote Generator, controlled by the host app. (Note: Requires AudioTools 6.6 or later).

Set up your mic in the front of the theater, and do your testing in another room, or put AudioTools Wireless and the mic inside a loud car or club, or set it up outside, monitoring the sound outside of the building. …

AudioTools Viewer for Mac

AudioTools Viewer for Mac lets you open AudioTools  XLS files on your Mac. 

Some of the key features in AudioTools Viewer are:

  • Open XLS plot files from AudioTools
  • Plot multiple curves on a graph
  • Organize sets of plots into Project Files
  • Enter project and company data
  • Print reports
  • Send a saved Project file to another user, or back to your office

Remote Controlled Signal Generator

You can control another iOS device running our standalone Generator app from within AudioTools. Just make sure both devices are on the same WiFi network, and go to the WiFi Connect page on both apps. 

First, download Generator from the App Store. Start the Generator app on the second iOS device. Tap the WiFi symbol to open the connection page.

iRemote for Smaart® 7

iRemote is for users of Rational Acoustic's Smaart 7 running on Mac or PC. iRemote lets you operate Smaart 7 remotely over WiFi, on your iOS device. Perfect for iPad, it also runs on iPhone or iPod touch. Buy once and get both platforms.

You can view any single measure that is running on the host computer, and control things like the host generator, and start and stop measures.
