Still hearing echo, reverb, or metallic artifacts?
Constant noise (hiss, hum) is handled above. AI Deep Clean sends the track to a restoration model on Cloud Assist; it was trained on music, not on noise specifically, so preview 30 seconds first.

How to Remove Background Noise
- 1 Upload any audio file — MP3, WAV, FLAC, OGG, or M4A. Up to 30 minutes.
- 2 Slide to control how aggressively the noise gate removes background sounds. Preview in real-time with A/B toggle.
- 3 Export as WAV (lossless) or MP3. The noise gate runs on your device and never uploads your file; the optional AI deep clean uses Cloud Assist.
Frequently Asked Questions
What types of noise can this remove?
Constant background sounds like air conditioning, fan hum, computer noise, tape hiss, and street ambience. The spectral gate analyzes the quietest parts of your audio to build a noise profile, then reduces frequencies that match that profile.
Can it remove echo or reverb?
The free noise gate handles constant background noise. Echo and reverb are non-stationary — they change over time and are tied to the source audio. Removing them needs AI processing: use Remove Echo, which runs AI Echo Removal on Cloud Assist.
Will it damage my voice or music?
At moderate settings, the spectral gate preserves all frequencies above the noise floor. Start at 30-50% and increase until the noise disappears. If you hear "watery" artifacts, reduce the setting slightly.
How is this different from Audio Enhancer?
This tool focuses specifically on removing constant background noise. Audio Enhancer is a broader repair tool that also improves clarity, restores dynamics, and adds high-frequency detail. Use this tool first for noise, then Audio Enhancer for overall improvement.
