This is a camera setting option on iPhone 15 that you should take note of

The iPhone 15 and iPhone 15 Pro have now been in the hands of buyers for a few weeks and during that time, the biggest problem, the overheating error, has also been identified by Apple and an update has been released to fix it. However, there are still some other small issues on the new iPhone line that can affect the user experience, but have not been mentioned much. For example, a camera setting can cause audio distortion when recording video. Luckily, the fix only requires a few taps in the Settings app.

The story is that the new generation iPhone models have a feature that allows recording stereo sound while recording video, mainly by using multiple microphones (located on the bottom edge and earpiece of the phone) to record. Get more realistic sound. In particular, the sound that the microphone picks up will also change when zooming in on the camera, to simulate the user moving the camera and phone closer or farther from the target. As a result, the sound from the zoom target is amplified but does not always work correctly, especially if the person holding the camera is talking while zooming the camera.

A technology YouTuber with the nickname DankPods highlighted this issue in a recent video about his video recording experience on the iPhone 15 Pro Max. In the DankPods test (at minute 5:07), it can be seen that the sound effect is significantly affected when the person holding the camera speaks while recording a video. In this mode, the volume of the cameraman's voice will vary significantly between different camera zoom levels.

Apple may be trying to simulate the sound that the camera would pick up when physically moving back and forth, and in fact the feature often works fine if there's no narration sound coming from behind (the person is hold the phone).

Thankfully, you can turn off stereo capture in settings to stop the zoom sound effect. First, open the Settings app on your iPhone , then navigate to Camera > Record Stereo Sound and turn it off .

DankPods also explains that some other default camera settings also sometimes affect the user experience. such as auto FPS feature and auto lens change. To be fair, these features are very useful in many situations, but sometimes also bring side effects in some cases.
