Why is iPhone 14 Pro video recording audio quiet and muffled?

iPhone 14 Pro – Camera App Audio Becomes Very Quiet and Muffled During Recording (Voice Memos Perfect)

I’m using an iPhone 14 Pro on latest iOS (26.1) and I’m having a consistent audio issue only in video recording apps.

Whenever I record video using:

Default Camera app
Blackmagic Camera app

…the audio starts normally, but then randomly becomes extremely quiet and muffled, and sometimes goes back to normal again. This happens every single time I record, on both front and rear cameras.

However, the microphones seem to work perfectly in other apps:

Voice Memos = perfect audio
ReLens, TikTok = perfect audio

The quiet/muffled audio in iPhone 14 Pro video recordings is almost certainly due to software processing of the internal microphones — dynamic gain control or noise reduction in the Camera framework — rather than a hardware problem. Workarounds include changing Mic Mode to Standard, using a third-party app that bypasses processing, using an external mic, or resetting settings. Apple is aware that certain iOS updates have triggered this, so a fix may come in a future iOS release.

You need to have Apple perform diagnostics on your iPhone. It can be done in person at an Apple Retail Store or at an Apple Authorized Service Provider. You can also contact Apple Support and request remote diagnostics.

If you’re in the US, please call 1-800-MY-APPLE, or outside the US, consult the support articles below. In Canada, call 1-800-263-3394.
