About the AI Noise Remover
By Ismail Farooq, founder of SongUp AI · Updated 5 November 2026
Completely free: free account, no card needed, no credits, no limit. It runs in your browser, so your audio stays on your device.
The AI Noise Remover cleans background noise out of speech and vocal recordings — hiss, hum, fans, traffic and room noise. It learns what the noise sounds like from your own recording and removes it with a smooth spectral (Wiener) filter, in stereo, directly in your browser so your recordings stay private.
Pick De-Noise for hiss and background noise, De-Reverb for room echo, or Full Cleanup for both, set the strength, then switch between the original and cleaned versions before downloading the result as WAV.
What you can use it for
- ✓Clean up podcast and interview recordings
- ✓Rescue voice notes recorded in noisy places
- ✓Reduce hiss on vocal takes before mixing
- ✓Improve the audio of video voice-overs
Common questions, answered
Frequently asked questions
What is the best free way to remove background noise from audio online?
+
For a voice recording, use a noise remover that runs in your browser, such as this one: it is free with a free account, the file never leaves your device, and you download the cleaned audio as WAV. Choose De-Noise, De-Reverb or Full Cleanup, set the strength from 10% to 100% (Light, Medium, Strong or Maximum; it starts at 60%, Strong) and compare the original with the cleaned version before you download. Web tools such as Adobe Podcast Enhance Speech and MyEdit have you upload the file to their site, and Audacity’s free Noise Reduction effect does it on your computer from a noise sample you select. Last checked 5 November 2026.
Does it work on music?
+
It is designed for voice. On full music mixes it may treat instruments as noise, so use it on vocal or dialogue recordings.
Which mode should I choose?
+
Start with De-Noise at the default strength. Use De-Reverb if the problem is room echo, and Full Cleanup if you hear both. Lower the strength if the voice starts to sound thin.
How do I remove background noise from audio for free online?
+
Open the Noise Remover, add your recording, keep De-Noise selected and run it. Listen to the original and the cleaned version back to back, lower the strength if the voice sounds thin, and download the WAV.
Can I remove background noise without uploading my file?
+
Yes. The cleanup runs in a worker inside your browser, so the recording stays on your device, on a computer or a phone.
How do I remove echo from a recording?
+
Choose De-Reverb, or Full Cleanup if there is background noise as well. It works best on a voice recorded in a room; it cannot fully rebuild a voice recorded very far from the microphone.
Why does a recording with pauses clean up better?
+
The Noise Remover learns the noise from your own recording: for each frequency it takes the level of the quietest tenth of the recording as the noise. A recording with a few seconds of pauses, or a second of room sound before you start speaking, gives it a clean picture of the noise. Noise that keeps changing is harder to learn.
What can it not remove?
+
It learns steady noise from your recording, so sudden sounds such as a door slam, a dog bark or another person talking stay in. To pull a voice out of music, use the Stem Separator instead.
Which formats can I upload?
+
MP3, WAV, M4A, FLAC and OGG. The cleaned audio downloads as WAV, in stereo if the recording is stereo.
Are recordings uploaded?
+
No, processing runs on your device.
Do I need an account?
+
Only a free one. It is completely free with a free account: no credits and no limit. It runs in your browser, so your audio never leaves your device.
