How do I compare the original and the cleaned file?
Play these five real recordings and switch between the original and the cleaned version. The fan should drop, and the voice should still sound like the same person. Your own upload gets the same free 30-second comparison before you pay.
Five real recordings with a fan, an air conditioner, a dishwasher, or a copier behind the voice. The background score rose on every one, from 1.48 to 4.24 on the distant fan. On the fan and the copier samples, the voice scored about 3 out of 5 for naturalness, so listen for a thin voice on your own file.

Which machine noise is this page for?
A fan is steady: the same sound, all the time, under every word. That is the easiest kind of noise to lower without hurting the voice.
Desk and ceiling fans
A fan is loud but steady. In our fan sample the background score went from 1.64 to 4.08.

An AC unit adds a soft roar to a room. In our sample it dropped and the voice scored 4.55 for naturalness.

A dishwasher or a fridge in the next room sits under a kitchen recording. It drops like a fan does.

A copier or a computer fan adds a mechanical whir. The noise drops, but check that the voice does not turn thin.

You do not sample the fan first. Upload the recording and listen.
No noise profile
Audacity and Audition ask for a second of fan-only audio. EraseNoise does not.
Scores you can check
The five recordings above show how much each machine dropped, including the two where the voice lost some body.
Audio or video
A recording downloads as WAV. A video downloads as MP4 with the same picture.
Why not just turn the fan off next time?
Next time, do. For a recording you already made, a cleanup is faster than a retake.
The take is already good
The words and the timing are right. Only the room was noisy.
Thirty seconds tells you
If the preview sounds thin, keep the original. If it sounds clear, process the rest.
Which files can I upload?
Upload the recording as it is. It does not need a fan-only gap.
MP3, WAV, M4A, AAC, OGG, Opus, or FLAC
Audio files download as WAV.
MP4, MOV, M4V, or WebM
A video with fan noise in the soundtrack downloads as MP4 with the same picture.

Where to remove fan noise from audio
A podcast recorded in summer
The fan or the AC was on for the whole episode. Clean it instead of re-recording.
A tutorial with a loud laptop
The computer fan spun up under the narration. Lower it and keep the screen recording.
A lecture in a ventilated room
A ceiling fan or a vent hums under the teacher. Make the recording easier to follow.

Frequently asked questions
How do I remove fan noise from audio?
Upload the recording at the top of this page and compare a 30-second preview, original and cleaned. Download the full file only if the fan is lower and the voice still sounds natural.
Can I remove air conditioner noise too?
Yes. An air conditioner is steady like a fan. In our sample the background score went from 3.70 to 4.20 and the voice scored 4.55 out of 5 for naturalness.
Does this remove hum and hiss?
Electrical hum and mic hiss are steady too, and they usually drop the same way. Check the preview, because lowering hiss can make a quiet voice thinner.
Do I need a noise sample like in Audacity?
No. You do not mark a fan-only section. Upload the whole recording.
Why does the voice sometimes sound thinner?
A loud fan covers part of the voice too, so removing it can take some of the voice with it. In our fan and copier samples, naturalness ended near 3 out of 5. If your preview sounds thin, keep the original.
How many free previews do I get, and how large can the file be?
You can hear the 30-second preview 3 times in 24 hours without an account, and 20 times in 24 hours after you sign in. The upload limit is 2 GB. The full file is billed in whole minutes, rounded up, with a minimum of 1 minute.
