Bluetooth and AirPlay Output

You can use Bluetooth or AirPlay devices for output, while using the internal iOS device mic, headset connected mics, or Lightning devices such as our iTestMic2 or iAudioInterface2.

To do this, follow these steps:

  • Connect your microphone to AudioTools, if you are using an external mic
  • Open the iOS control panel. This is a swipe down from the upper-right corner on most iPhones and iPad
  • In the Music contro,. tap the circle in the upper right corner to show available devices
  • Select your AirPlay or Bluetooth audio device
  • Back in AudioTools, audio output will be directed to linked device. If there is no audio, or if you hear stuttering audio, go to the Settings->General->Global audio page in AudioTools, and turn on "Limit Sample Rate to 44.1k", as many BT devices don't handle our default 48k
  • Adjust the audio level of the connected device using the iOS devices volume up/down buttons

To return audio output to the normal path, go back to the sound control panel and select the iOS device

Compatible Modules and iOS Devices

Some iOS devices can have issues with a bluetooth connection that sounds like stuttering audio. We have been been able to correct this in most modules, but the ones that require tightly-coupled input and audio for for timing purposes cannot be fixed. The modules that may have this issue are listed here:

  • Transfer Function
  • LARSA (although now you can run LARSA in External Trigger Mode and play the sweep from another device)
  • Impulse Response internal sweep mode, use an external signal

All other modules will work properly over Bluetooth or AirPlay.
