Noise Reducer - audio enhancer for iPhone

Introducing Noise Reducer — Audio Enhancer

Have background sounds been spoiling your recordings? Noise Reducer is an easy-to-use utility for cleaning audio and video tracks by removing unwanted ambient noise while keeping voices natural and intelligible.

What it does

• Applies intelligent denoising filters to audio and video files.
• Preserves speech clarity while reducing hiss, hum, and background chatter.
• Works directly on your device so processing is fast and private.

Supported file types

• Video clips recorded on your device are fully supported.
• Standalone audio files can be cleaned in the same simple workflow.

How to use

1. Pick an audio or video file from your iPhone’s storage.
2. Let the app process the file — the noise reduction runs automatically.
3. Save or share the cleaned version once the filter finishes.

Privacy and offline processing

Noise Reducer performs all filtering locally on your phone. Because nothing is uploaded to external servers, your media stays on your device and can be processed even without a network connection.

Recommended alternative

Streisand Free is a top suggested option if you want a different approach to noise reduction and audio improvement.
