Why does the Xiaomi 17 Ultra record white noise or high background noise when audio and video recording?
If the Xiaomi 17 Ultra records white noise or high background noise when audio and video recording, please refer to the following explanation:
1. In very quiet environments, microphones amplify ambient sound to maintain balanced audio capture, which can make background noise more noticeable.
2. A controlled level of soft ambient noise can help reduce the perception of abrupt silence and relieve listening pressure during playback.
3. Audio processing algorithms are tuned to preserve natural sound details, which can include faint environmental tones.
4. The recording system undergoes strict acoustic testing to ensure compliance with quality standards.
5. This phenomenon is related to recording sensitivity and sound processing rather than a malfunction. Please feel confident in using your device.
