Edit Spatial Audio with Audio Mix on iPhone 16 models

Open a video, then tap

Tap Audio Mix, then choose one of the following:
Standard: Play the original audio you recorded.
In-Frame: Reduce sounds and voices from sources not visible in the video frame.
Studio: Reduce background sounds and reverb, to make it sound more like you’re recording in a professional studio.
Cinematic: Put all the voices onto a front-facing track and leave environmental noises in surround, like the audio in movies.
Drag the slider below the mix options to increase or decrease the effect and background noise levels.
Tap Done.
