Inject an audio file

On an open device that has audio injection enabled, you can inject an audio file to mimic microphone reception. This is helpful when testing actions in apps that rely on audio input. Audio injection mocks the use of the microphone by using an uploaded audio file in .mp3 or .wav format and presenting it to the application as if it was read by the device microphone. The file cannot exceed 150 MB.

Limitations

Audio injection is not supported on devices with a USB-C port.

In addition, for calls, audio injection is not supported on devices running iOS 17 or later.

For calls, audio injection can also be supported through Bluetooth. This implementation is only available in hybrid clouds and only to select customers. For more information, see Bluetooth audio connectivity.

If your application allows voice control or dictation without the option to select the source of the audio input, install the .ipa file with sensor instrumentation enabled. This automatically moves the audio source from the built-in microphone to the connected audio cable (handset mic).
