For higher-quality audio than the built-in microphones can deliver, you can record with an external microphone in ProCamera's Video camera mode. ProCamera supports wireless Bluetooth microphones and wired Lightning/USB-C microphones, and — with the proper adapter — USB microphones and 2.5mm/3.5mm/6.35mm jack microphones.
When a supported external microphone is connected, ProCamera detects it automatically and uses it in preference to the iPhone's built-in microphones. The Video Info panel in the viewfinder confirms which microphone is active: the connected device's name appears briefly, then an icon next to the audio meter indicates the input source. The audio meter shows one level for a mono microphone and two for a stereo microphone.
Using a Bluetooth microphone
In the iOS Settings app, turn on Bluetooth and pair the Bluetooth microphone with your iPhone.
In ProCamera, (1) tap the Control Panel button and (2) activate the Bluetooth option, which selects the connected Bluetooth microphone as the audio input. A white Bluetooth icon means it is off; a blue icon means it is on.
Check the Video Info panel to confirm your Bluetooth microphone is connected: (1) a notification naming the connected device appears within a few seconds, and (2) a Bluetooth icon is then displayed, indicating the external Bluetooth microphone is in use.
Using a Lightning/USB-C microphone
Plug the microphone or headset into your iPhone's Lightning or USB-C connector. No settings in the app need to be changed — a compatible device starts working immediately. To use a USB type A microphone, connect it through an adapter; it then behaves like any other wired microphone.
Check the Video Info panel to confirm your Lightning or USB microphone is connected: (1) a notification naming the connected device appears within a few seconds, and (2) an icon (a cable icon for a wired connection) is then displayed next to the audio meter, indicating the external microphone is in use.
Using a 2.5mm/3.5mm/6.35mm jack microphone
There are several types of jack connector, and the one your microphone uses determines how you connect it to your iPhone.
- TRRS connector
If your headset has a TRRS connector (3 rings on the plug, designed for smartphones), connect it to your iPhone directly or through the Lightning/USB-C to jack adapter. It works without any additional equipment.
- TRS connector
Most standalone cable microphones use a TRS connector (2 rings). A TRS microphone won't work if you connect it directly to your iPhone or through a plain Lightning/USB-C to jack adapter. To use one, add either a Headphone/Mic Splitter or a TRRS-to-TRS adapter.
For other or less common microphones — such as 2.5mm/6.35mm jack or USB models — make sure you use the proper adapter for the connection.
