Clear out hiss, hum, fans, and room noise in one step. Upload a file, hear the cleaned result, and download it free.
This free tool lets you remove background noise from audio in a single step, no editor and no plugins required. Drop in a recording that is buried under hiss, a humming fan, traffic, or general room tone, and it suppresses that steady background while keeping the voice clear and natural. Within seconds you get a cleaned version you can play back and download.
It is built for the messy places real recordings happen. Interviews captured in a noisy cafe, lecture recordings picked up from the back of a hall, video calls with an air conditioner droning in the background, field notes recorded on a phone: these are exactly the situations where background noise creeps in and makes audio tiring to listen to. The tool learns the constant noise underneath your speech and pulls it down, so the words come forward.
Removing background noise from audio does more than sound nicer. Cleaner speech transcribes far more accurately, so if your next step is a transcript or captions, denoising first is the single best thing you can do for the result. The tool runs at a balanced medium strength on purpose, clearing obvious noise without the robotic, underwater sound that aggressive denoisers leave behind. You hear the cleaned file play right in your browser before you decide to download it.
Once your recording is clean, level it out with the audio normalizer, turn it into text with the audio to text converter, or build captions with the SRT generator. Recording something new? Check your setup first with the mic test.
Files are capped at 100 MB and free use is limited to 30 requests per hour. Need to clean up large batches or automate noise removal inside your own app? See pricing.
The tool analyzes your recording, learns the steady background sound behind the voice such as hiss, hum, fans, or room tone, and then suppresses it while keeping the speech intact. It runs at a balanced medium strength that removes obvious noise without gutting the natural sound of the voice. Upload a file, and you get a cleaner version back in seconds.
At medium strength, no. Aggressive noise removal is what makes audio sound robotic or watery, so this tool is tuned to a moderate setting that clears background noise while leaving voices natural. Very noisy recordings, where the noise is nearly as loud as the speech, are the hardest cases and may show mild artifacts, which is simply the limit of what any denoiser can recover.
It is designed to remove steady, unwanted background noise like air conditioning, traffic, hiss, and hum, not to cleanly separate a song from a voice. Music shares the same frequencies as speech and moves constantly, so a general noise remover cannot pull it out without harming the voice. For that you need dedicated source separation, which is different from noise reduction.
Yes. As soon as processing finishes, the cleaned file loads into a player right on the page. Press play, compare it against your memory of the original, and only download if you are happy with it. Hearing the before and after is the fastest way to judge whether the noise reduction did what you needed.
Yes. Your file is uploaded over an encrypted connection, processed, and then held behind a private access token that only you receive. Files are automatically deleted after 30 days, and we never sell your recordings or use them to train models.
