Frequently Asked Questions
How does browser-based noise removal work?
The tool uses DeepFilterNet3, a state-of-the-art neural network for speech enhancement, compiled to WebAssembly. It runs entirely in your browser using your device's CPU, no audio is ever sent to a server.
What types of background noise can it remove?
DeepFilterNet3 is trained to remove a wide range of noise types including HVAC hum, keyboard clicks, street noise, crowd noise, electrical hiss, and wind noise, while preserving speech quality and naturalness.
Which audio formats are supported?
The tool accepts any audio format your browser can read (typically MP3, WAV, M4A, OGG, FLAC) and can export as WAV, MP3, M4A (AAC), or OGG (Opus). M4A and OGG output requires Chrome or Safari.
Is there a preview before I download the full file?
Yes. The tool processes the first 60 seconds of your audio as a preview so you can compare the before and after before committing to processing the full file.
How does this compare to paid noise removal tools like Adobe Enhance?
DeepFilterNet3 achieves state-of-the-art quality and is competitive with commercial tools. It's particularly strong for speech recordings, podcasts, and interviews. The main difference is it runs on your device so very long files may take longer depending on your hardware.
Is this audio noise remover really free?
Yes, completely. There is no sign-up, no account, no watermark, and no file limit imposed by us. The AI model runs on your own device, so there are no server costs to pass on to you.
Does it work on a phone or iPad?
It runs in mobile Safari and Chrome, but noise removal is CPU-intensive and a phone will process a long file noticeably slower than a laptop. For recordings over a few minutes, a desktop browser is the better experience.
Can I remove background noise from a video file?
This tool works on audio files. To clean the audio in a video, extract the audio track first with the File Converter, run it through this noise remover, then recombine it — or use the FFmpeg Web CLI, which can do both steps in the browser.
How long can my audio file be?
There is no hard limit, but processing time scales with length and everything runs on your device's CPU. Files up to about 30 minutes are comfortable on a modern laptop. Use the 60-second preview first to gauge speed before committing to a long file.
Does noise removal reduce audio quality?
DeepFilterNet3 is designed to preserve speech while suppressing noise, so voices stay natural at moderate settings. Very aggressive settings on an already-clean recording can introduce artifacts, which is exactly what the before-and-after preview is there to catch.
Can I use the cleaned audio in wavreel?
Absolutely. A noise-cleaned recording is perfect to upload into wavreel, clean audio leads to more accurate AI transcription, better word-synced captions, and a more professional final video.
