Q: Wow new iOS 15! Is AudioTools ready yet?

A: No! Don’t upgrade to the beta, please allow us time to adapt to all of the changes. 

Q: My Surround Generator seems broken now on iOS 13, how can I fix this?

A: Apple seems to have broken this by inserting a sample rate converter or filter into the audio signal path, so our surround data is being corrupted. No known workaround at this time, other than switching to an iOS device with iOS 12 or earlier installed. We have escalated this to Apple but it is unclear when or if they will change this. 

Q: Can I use iAudioInterface2 on the new iPads that have USB C?

A: It will work as an audio interface right now, but the special commands to set things like gain and phantom power don’t work, since Apple has not yet given us the tools to support it on iPad, as they do on Mac OS. We are hoping that this is a temporary situation, but we have no control over what Apple does in their software.

The workaround is to set up the iAudioInterface2 on an iOS device, using the “Non-AudioTools Settings” selection on the Settings menu. This will store the settings so that they will be in effect when you use it with the iPad.

Q: Can I extend the Lightning cable?

A: We have had success with this particular Lightning extender on iOS 13.4.1:


6.6FT/2M White



Q: I have the older model with the fixed 30-pin cable, how can I use this with the new iOS Lightning devices?

A: You can use the Apple 30-pin to Lightning adapter to use this model with the newer Lightning-equipped iOS devices. All features are supported with no loss of audio quality. Charging is also supported, although not for the larger 12.7" iPad Pro. Note that only the actual Apple adapters work, the third-party copies only support charging and they will not work with MFi accessories. Here is a link to the proper adapter. We prefer the one with the short wire, rather than just the hard plastic model.

The USB feature of the current iAudioInterface2 model is not available with the fixed-cable units.

Q: I'm having problems using the USB connection with a computer. How can I fix this?

A: There are some delays in the firmware, follow these steps and it will work fine.

1) Unplug all cables from the interface. 

2) Start the iAudioInterface Control panel, if you are on Mac.

3) Plug the USB cable to the interface only, but do not plug it into the computer yet.

4) Wait a full 20 seconds.

5) Now plug the USB connector into the computer. 

6) Select the iAudioInterface2 from the Mac Sound Settings panel, or from the Windows Sound Control Panel.

Q: Will this work with my iPhone? What about the iOS devices?

A: Yes. iAudioInterface2 suppports all Lightning connector iOS devices.

Q: Can I use this with my computer analysis software?

A: Yes! Just connect it using the included USB cable and select the iAudioInterface2 from the computer’s control panel.

Q: It seems like the battery loses its charge over time, why is that?

A: Always unplug the interconnect cable, to prevent it from causing the battery to slowly discharge.

Q: My iAudioInterface2 won’t charge my new iPad? What happened, it used to?

A: It seems that Apple has changed the requirements for charging newer iPad models, like iPad Air. This has affected a lot of people, using lots of different chargers. I don’t have any official word on this, but it appears as if the new iPads are less tolerant for charging unless they have the full current available. Although our charging passed Apple testing at the time, and still works with older iPads, it seems like now they are being more strict. This only affects the first gen of iAudioInterface2, which has a fixed cable and 12V PSU. The current model, with the removable cable, does not have a problem charging any iPad model.

Q: The 30-pin connector doesn't latch well into my iPhone dock connector. What's wrong?

A: Often pocket lint and dust build up inside the connector, preventing our plug from making good contact and seating. You can sometimes tell that this is happening when the latches don't both click.

To fix this, power off the iPhone, and look in the connector with a bright light and a magnifier. You will need something sharp, like a pin, to reach in and remove the lint. Once loosened, you can often blow sharply and remove the rest. When you are able to easily plug in the connector and hear both latches click you are done.

Q: And can I use the mic from my original iAudioInterface with this new one?

A: No. The original iAudioInterface mic will not work with iAudioInterface2, since the new interface requires a balanced XLR phantom power mic, and the older mic is 1/4" single-ended not phantom-powered.

Q: Why won't this work with my iPhone 3GS, or iPod touch 3?

A: Those devices have analog line inputs, and iAudioInterface2 uses a digital audio link.

Q: Does iAudioInterface2 include the mic shown in the pictures?

A: No. Since so many of our customers have their own microphones, we decided not to include one. AudioControl, our distributor, is making several microphones available with the unit in case you do not have one.

Q: When running on the internal battery, will it also feed power to my iPad?

A: No, that is not possible. Power is sent to the iPad (or other iOS device) only when the external power supply is attached.

Q: Why no digital input?

A: Since the iOS device is always the clock master, we would have to include a sample rate converter to match the iOS device clock, which kind of defeats the purpose of a digital input. Also, we are short on panel real estate.
