When trying to record you might get an alert that says audio input isn't accessible. Or you might not hear sound, see waveforms, or see audio meters move when recording. This can happen if you're using the built-in microphone on your Mac, an external USB mic, or the inputs on an external audio interface to record audio.
To record audio, allow the app to access audio inputs:
- Close the app you're using to record audio.
- On your Mac, choose Apple menu > System Preferences, click Security & Privacy, then click Privacy.
- Click Microphone.
- Select the checkbox next to an app to allow it to access the built-in microphone on your Mac, an external USB mic, or the inputs on an external audio interface.
- Open the app and try to record audio again.
If you're using an external microphone or an external audio interface to record audio and it's still not working, check with the manufacturer of your device for software updates and information on compatibility.
