How do I compare the original and the cleaned voice?
Buzz is easiest to hear in the gaps between words, but judge the words. Play 30 seconds of your own file, original and cleaned, before you pay. The voice should stay full.
Original
The opening with the buzz still under it. Listen in a pause first so you know what the noise sounds like.
Cleaned
The same 30 seconds after the buzz is lowered. The speaker should still sound like the same person.
Where do buzz and hum in a recording come from?
Hum is a low, smooth electrical tone. Buzz is the same problem with a raspy, bright edge, the buzzing sound you hear from a bad cable or a dimmer. Both sit under everything and do not change when the speaker stops. Remove buzz and hum from audio when that tone is what makes a usable take hard to listen to.
Ground loops
A mixer, a laptop on its charger, and a speaker on different outlets can add a low hum to every word. The cable fix is better next time. This page is for the take you already have.
Cheap or damaged cables
An unshielded cable picks up a raspy buzz from nearby power. The noise stays the same level for the whole file, which is the kind this tool lowers best.
Light dimmers and chargers
A dimmer, a fluorescent tube, or a phone charger near the mic can add a high whine. Check the preview: a very loud whine may leave a trace.
Camera and guitar amp hum
A camera preamp or an amp left on in the room adds a hum under a talking-head clip. Upload the video and keep the picture.
Why choose EraseNoise to remove buzz and hum from audio
You do not find a quiet second or tune a notch filter to 50 or 60 Hz. The voice is the reference.
No noise print and no notch filter
An editor asks you to select a noise-only gap, or to guess the mains frequency and its harmonics. Here you upload the file and listen.
The voice stays, the tone drops
The model keeps speech and lowers what is not speech. A buzz that is louder than the voice may leave a trace. The preview shows how much.
Audio or video, one upload
A voice file comes back as WAV. A video comes back as MP4 with the same frames, so a buzzing interview does not need a new export.
What should I listen for?
A silent gap is not the test. Judge the consonants and the low end of the voice.
Listen to the words, not the pauses
A clean pause with a thin voice is a worse file. Keep the download only when the words still sound full.
Turn the noise reduction down if needed
The Noise reduction control mixes some of the original back in. Pull it down if a deep voice loses its body.
Which files can lose their buzz or hum?
Upload the recording that already has the buzzing or hum in it, up to 2 GB.
MP3, WAV, M4A, AAC, OGG, Opus, or FLAC
A voice file downloads as WAV.
MP4, MOV, M4V, or WebM
A video downloads as MP4. The frames match the file you uploaded.

Where to remove buzz and hum from audio
A podcast with a ground loop
The mixer hummed through the whole episode. Remove the hum from the full take instead of re-recording the guest.
An interview filmed near a light
A dimmer or a tube light buzzed under the answers. Upload the video and keep the same shot.
A lecture through a cheap cable
A classroom mic picked up a steady electrical tone. Keep the WAV when the lesson is easier to follow.
Is buzz or hum the real problem?
Use this page when a buzzing sound or a steady electrical hum sits under speech. A ringing room is echo or reverb, and a song is music.

Frequently asked questions
How do I remove buzz and hum from audio?
Upload the recording at the top of this page and compare 30 seconds, original and cleaned. Download the WAV or MP4 only if the buzzing is lower and the voice still sounds full. You do not need to sample a noise print.
What is the difference between buzz and hum?
Both are electrical noise. Hum is the low, smooth tone of the mains frequency. Buzz adds bright, raspy overtones on top of it, so it sounds like buzzing. This tool lowers both under speech, and you do not need to tell them apart first.
Does it remove 50 Hz and 60 Hz hum?
Yes, a steady mains hum under speech is the kind of noise this tool lowers. You do not need to know which frequency your country uses. A hum louder than the voice may leave a trace, so check the preview.
Can I remove a buzzing sound from a video?
Yes. Upload an MP4, MOV, M4V, or WebM. The cleaned download is an MP4, and the picture is not changed.
Will it remove buzz from music or a guitar track?
No. The model keeps speech and lowers everything else, so it would lower the instruments too. Use it on someone talking.
Why does the voice sound thin after cleaning?
A buzz that overlaps the low end of the voice can take some of the voice with it. Turn the Noise reduction control down, or keep the original if the preview does not sound better.
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.
