How to Remove Background Noise From a Video for Free

How it works. Go to vidclean.net/remove-background-noise. Upload your video or audio file. VidClean runs DeepFilterNet3 — an open-source AI model developed by researchers at FAU Erlangen-Nürnberg — to isolate voice and strip everything else. Download the cleaned file. That is the entire process.

What it costs. Nothing. No account required, no watermark, no settings to fiddle with.

File support. MP4, MOV, MKV, WebM, MP3, WAV, M4A up to 2GB and 30 minutes.

Best for. YouTubers fixing fan or AC hum on home recordings, podcasters cleaning up Zoom and Riverside captures, anyone who recorded outdoors and has wind on the mic. Run your raw file through, get a cleaned version back, then open your editor with audio that does not fight you.

Limitation. Video inputs return as MP4 with the original video stream untouched (no quality loss on the visual side). Audio inputs return as MP3. If your source is heavy music with vocals layered on top, no AI noise tool — VidClean included — will give you clean isolated speech. The tool is tuned for voice content with environmental noise, which covers most use cases.

How it works. Sign in with an Adobe account at the Podcast Enhance page. Upload an audio file. Adobe runs its speech enhancement model and gives you a cleaned WAV back.

What it costs. Free, but you need an Adobe account. Free accounts get capped at one hour of processing per month at the time of writing; longer processing is gated behind Creative Cloud subscriptions.

The catch. Audio only — if your source is a video, you have to extract the audio first, clean it, then remux it back into the video manually. That adds three steps and means you are now in the editor anyway. Adobe Enhance also tends to push voices toward a "studio podcast" sound that can feel processed if your speaker has a quiet or breathy delivery.

Best for. Podcasters who already pay for Creative Cloud and are comfortable handling audio extraction and remux in their existing workflow. If you do not already have an Adobe account, the friction probably is not worth it.

How it works. Install Audacity. Import your audio. Select a section of the file that is silence except for the background noise — at least half a second of pure noise. Open Effect → Noise Reduction → Get Noise Profile. Then select the whole file and apply Noise Reduction with the captured profile. Start with the defaults (12 dB reduction, sensitivity 6) and adjust if the result is too aggressive or too gentle.

What it costs. Free. Open source. No account, no watermark, no time limit. Same value props as VidClean, but the workflow is manual.

The catch. You need a sample of pure noise in your file to capture the profile. If your recording starts the moment you began speaking, there is no isolated noise to grab. You also have to do this once per file, and Audacity's noise reduction is a 20-year-old spectral subtraction algorithm — it works, but it does not match what modern speech-trained models produce on hard cases like wind or non-stationary noise.

Best for. Power users who want fine-grained control, people working with audio that has a clear noise floor sample, or anyone already comfortable in Audacity.

How it works. Create an account, upload an episode, Cleanvoice processes it and returns a cleaned version with options for additional cleanup steps — mouth sounds, "uh"s and "um"s, dead air, stuttering. You review and accept or reject each suggested edit.

What it costs. Paid subscription, with pay-per-hour or monthly plan options. Free trial available for new accounts.

Best for. Podcasters producing multiple hours of content per week who want both noise reduction and filler-word cleanup in one pass and are willing to pay for the convenience. If you just need background noise gone on a single video, this is overkill.

It depends on what you have and what you need.

One file, fast, free, no account: Use VidClean. Upload, wait a minute, download. Works on both video and audio in a single step. The clear default.

You already pay for Adobe and your workflow can handle audio extraction: Use Adobe Enhance Speech. Quality is competitive, but the friction adds up if you are doing it on every episode.

You want manual control and have a noise floor sample: Use Audacity. Free, offline, total control. Slower than the AI tools but predictable.

You make a lot of podcasts and want filler-word cleanup too: Use Cleanvoice. The most expensive option but the most batteries-included.

For most YouTubers and podcasters who just want clean audio on a single recording, the fastest path from messy raw file to clean usable file is still VidClean. Upload, wait, download. Then open your editor with audio that does not need any further cleanup.
