Problems with in-app purchases? See our page on troubleshooting in-app purchase problems. 

Q: Is it OK to update to the iOS 13? 

A: NO. We have not been able to run iOS 13 or test it on any devices. Generally the betas, especially the early ones, are very buggy and we already have reports of various audio problems. Please wait for out official update.

Q: What happened to the cool 3D waterfall graphs? I dont see them in the app now.

A: Apple had a problem with the graphics library that we were using so we were forced to remove them. We are in the process of replacing the graphics engine with a new much more powerful one, but it will take some time. We will have an update as soon as we can integrate the new improved library.

Q: RTA has started telling me my sample rate is too low, why?

A: It may be that some other hardware is connected by Bluetooth. Hearing aids have been known to cause this issue.

Q: Dropbox does not seem to be working.

A: Dropbox has cancelled support for our method of saving files. We are working on including Dropbox support in a future release, but for now we recommend using iCloud for automatic off-device storage.

Q: I can play one of the download files, but I can download it. How do I do that.

A: It depends on your browser.

  • Safari: Click on the Support link at the top of the page, scroll down the menu that pops up highlight Download, then slide over to highlight the STIPA file, and then right-click and select Download Linked File As… and select your destination. 
  • Chrome: Click on the Support link at the top of the page, then scroll down and click on the Downloads link. For most files, just click on the icon to download it. If it starts to play audio, click on the small mini-menu on the right side of the player, and select Save Audio As
  • Explorer (Windows 10): Click on the Support link at the top of the page, scroll down the menu that pops up highlight Download, then slide over to highlight the STIPA file, and then right-click and select Save Target As… and select your destination.

Q: I can't get iAudioInterface2 to connect to my computer. How do I do that?

A: See our USB Audio page for full instructions. 

Q: When I plug in iTestMic, the audio output stops working.

A: Plug in iTestMic first, then plug in the 1/8" (3.5mm) plug to the iOS device. Apple uses the last device connected for audio, so if you plug in the iTestMic after plugging in the analog connector the output will be routed to iTestMic, rather than the iOS device connector.

Q: Why aren't my gmail notifications coming through for SPL Graph?

A: Google has increased their security, and in some cases they are blocking emails we are sending from the app. See this link for information on how to turn on a setting to allow this, and note that you must use a computer, not an iOS device. 

Q: The Generator won’t turn on in Transfer Function. Or RTA, sometimes.

A: New behavior, the generator output is only on when the function is running. So tap the play button to start the function running and if the generator is switched on, it will play.

Q: Why can’t a I use a bluetooth speaker for my output signal playback?

A: Now you can! Starting with AudioTools 10.5, Bluetooth devices and Apple AirPlay are supported. See our new Bluetooth and AirPlay page for more information.

Q: The screen looks really dark (or too light!) How do I change it?

A: Go to Settings->General in the app, and turn on High Contrast Mode for the bright white screens, or turn it off for the dark theme.

Q: I upgraded to iOS 7/8/9/10, now I have no audio!

A: If you have no audio input, probably the microphone permission needs to be set: Settings->Privacy->Microphone on for AudioTools. Settings app, not AudioTools.

Q: I can't download saved data files, what's wrong?

A: The most common problems are not leaving the Export window open, not having both devices on the same WiFi router, or having a firewall in the router blocking port 9900. Also, we suggest using Dropbox for file transfers now that we support Dropbox.

Q: How do I get rid of the red bar on top of the screen when I exit the app?

A: The red bar indicates that AudioTools is still running in the background. This is new in 5.3. To stop AudioTools from running the background, return to AudioTools, and either stop the running task, or exit back to the menus.

Q: Will AudioTools run on iPad and iPad Mini?

A: Yes, see here for the details.

Q: I bought AudioTools on my iPhone, do I have to pay for it again to get it on my iPad?

A: No, as long as you are logged into the same iTunes store account, Apple allows you to install apps you have bought on other devices without charging you again. 

See our “Troubleshooting in-app purchase and standalone app issues” page.

Q: Something is messed up with this app -- what do I do?

A: Here are Apple's general FAQ concerning problems with apps.

Q: Who should buy AudioTools, rather than your individual apps?

A: First, anyone who may be purchasing iAudioInterface. Apple only allows a single app to communicate with an accessory, and this is the app that matches up to iAudioInterface. Second, anyone who has not started downloading our other apps. There are more features available in this app, including more comprehensive calibration, data file export, and of course the convenience of having multiple functions in one app.

Q: I need to re-install AudioTools. Do I have to pay for it again?

A: No. Apple knows what you have bought and will not charge you again, as long as you are logged into the same iTunes account that you used to buy the app the first time.

Q: I already downloaded some of your standalone apps, how can I get these apps in AudioTools without buying them all again?

A: Apple does not give developers a way to provide an upgrade path from one app to another. You have three options here:

1) If you plan on purchasing iAudioInterface, we will be providing a discount based on some of the existing apps that you have already downloaded and paid for. See our AudioTools Upgrade Program page for more information.

2) If you are not planning to buy iAudioInterface, stay with the individual apps. The functionality is very similar.

3) For a few standalone apps, after running them they will also be available in AudioTools. This includes SPL Graph, SPL Pro, FFT, STIPA, and Smaart Spectrum RTA.

Q: How can I find out what version of AudioTools I am running?

A: In AudioTools, go to the Settings menu, General page -- look on the bottom of the page.

Q: How do I get the new AudioTools upgrades?

A: Two ways. If your device (iPhone, etc) is on a WiFi network, just open your App Store app, tap Updates on the bottom of the screen, find the new AudioTools row, tap on it, and tap on the Upgrade button.

Or, from your computer, open iTunes, click on the "Apps" icon on the left side of the screen, under Library, and then follow the link on the bottom of the screen for "nn Updates available", and find the icon for AudioTools and tap Upgrade, or tap Upgrade all if you want all upgrades.

We recommend turning on Automatic Updates in your Settings app on your device.

Q: My iPhone is jailbroken, and I am getting an error message when I try to purchase any of the modules. Is there a workaround?

A: Although we don't support this directly, it appears to be a problem with something called Appsync. This has worked for some people on the modmyi forum:

  • Uninstall appsync
  • remove app you want to buy stuff for
  • reboot phone
  • reinstall app
  • reboot phone
  • buy in app purchases

Or, see this link for another method.

Q: What hardware can I use with my iPod touch to get a mic input?

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

Q: Why are the SPL readings different on different modules? How does that work:

A: See our "dB vs. dB" page to understand what the SPL numbers mean, and why they might be different on different modules.
