If I am recording my iPhone screen with Quick Time Player, how can I record my phone's audio as well?

Howdy moochiemoochers,

I understand that you're looking to record the audio generated by an app on your iPhone while recording its screen via QuickTime Player. This can be done by selecting the iPhone for both Camera and Microphone prior to starting the recording.

1. Connect your device to your Mac.

2. Open the QuickTime Player app.

3. Choose File > New Movie Recording.

4. Click the Options pop-up menu, then choose any of the following recording options:

   • Camera: Choose your connected iOS device.

   • Microphone: Choose a microphone if you have more than one microphone available.

   • Recording quality: Choose the recording quality. Maximum-quality recordings produce uncompressed files, which can use large amounts of storage space.

   Setting	Description
   High	H.264 video and 44100 Hz AAC audio
   Maximum	Apple ProRes 4444 video and 44100 Hz, uncompressed Linear PCM 32-bit audio

5. Adjust the volume control to hear the audio you’re recording.

6. Click the Record button to start recording, then click the Stop button when you’re done.

   To pause recording, Option-click the Record button , then click it again to resume recording.

7. Choose File > Save to save and name the recording.

All my best.

It doesn't help if you want to capture some gameplay. Music, YouTube, Instagram, Facebook — you can record audio from all these apps, but take any game — and you'll hear only silence. Another weird limitation from Apple…
