You record a video at a concert, play it back, and something's off. The crowd noise is gone. The room acoustics have vanished. Despite all that visual energy, the audio sounds clinical and lifeless, like it was recorded in a studio. Your iPhone did this on purpose.
A feature called Audio Zoom silently runs on your device, and every time you zoom while recording, it mutes background sounds to focus the microphone on your subject. Apple assumes you always want clean, isolated audio, but that kills the atmosphere that makes live videos feel real.
Most people have no idea it exists, let alone that it's been affecting their videos. iOS 26.4 finally added a toggle to turn it off.
How to turn off Audio Zoom
Open Settings, scroll down to Camera, then tap "Record Sound." You'll find the Audio Zoom toggle there. Turn it off.
From that point on, your iPhone will capture full ambient sound regardless of how much you zoom while recording.
A couple of things worth knowing. This setting requires iOS 26.4 or later. If the toggle isn't showing up, head to Settings, General, and Software Update.
When to use it...
Keep Audio Zoom off for: Concerts and live music videos where the roar of the crowd and the way sound bounces around a venue is half the point. Nature recordings, street footage, or anywhere the surrounding atmosphere is what gives the video its sense of place. Any time you want viewers to feel like they're actually there.
Turn Audio Zoom on for: Recording someone speaking over a noisy crowd where you only want their voice coming through clearly. Isolating a specific sound source at a busy event. Video calls or interviews where background noise would undermine the whole thing. Any time clean, focused audio matters more than immersion.
