How do I check copier noise before I pay?
Play the copier recording and pay attention to the voice as well as the machine, then compare it with the steadier dishwasher. After that, run 30 seconds of your own office recording free.
The copier is a mixed case. The machine dropped (background 2.81 to 4.10, overall 2.50 to 3.07), but naturalness ended at 3.03, so listen for a thin voice. A dishwasher, a steadier machine, did better. Scores are DNSMOS and NISQA predictions on a 1–5 scale for real copier and related machine recordings from the Microsoft DNS Challenge test set, processed with no hand edits.

Which office machine noise can be removed?
A copier mixes a motor, rollers, and clunks. The steady part drops best; the clunks and paper feed are harder.
A copier near the desk
An office interview or a call next to the copy room. The machine drops, and the voice can sound a little thin.
Hear the recordingA printer starting and stopping
Not tested separately. Printing comes in short bursts like the copier, so expect a similar result and check the preview.
A shredder or a laminator
Not tested. Loud machines close to the mic are the hardest case in general; move away from them for the next take if you can.
Server rooms and computer fans
A steady whir is like the fans we tested, which cleaned better than the copier.
Remove fan noiseWhy remove copier noise with EraseNoise?
A copier changes sound with every page, so a single noise profile does not fit it.
No profile to capture
Upload the file as it is. You do not need a stretch of only copier noise.
A strength control
Turn the Noise reduction control down to keep more of the voice when a loud machine thins it.
An honest sample
The copier is a mixed case in our tests. You can hear the trade-off before you upload.
How do I judge the voice after the copier is lowered?
With loud machines, judge the voice.
A thin or hollow voice
If the voice sounds processed, turn the Noise reduction control down and compare again.
Clunks on words
A paper tray clunk that lands on a word can leave a trace.
EraseNoise vs other ways to remove copier noise
A copier is loud and uneven, so every option has a cost.
| Option | Works best when | Falls short when |
|---|---|---|
| EraseNoise | The words must be clear and a slightly thinner voice is fine | The voice must sound fully natural |
| Audacity Noise Reduction | The copier hums steadily and there is a gap with only the machine | Pages feed and clunk at random |
| Cutting in an editor | The copier runs only between answers | It runs under the words |
| Moving the recording | You can book a room away from the copy room | The interview is already recorded |
Which office recordings can I upload?
Upload the meeting, interview, or lesson recording as it is, up to 2 GB.
MP3, WAV, M4A, AAC, OGG, Opus, or FLAC
A recorded meeting next to the copy room downloads as WAV.
MP4, MOV, M4V, or WebM
An office video downloads as MP4 with the same picture.

Frequently asked questions
How do I remove copier noise from audio?
Upload the office recording at the top of the page and compare the free 30-second preview with what you recorded. Download the full file only if the machine is lower and the voice still sounds natural.
How well does EraseNoise remove a copier?
On a real copier recording from the Microsoft DNS Challenge test set, EraseNoise raised the DNSMOS background score from 2.81 to 4.10 out of 5 and overall quality from 2.50 to 3.07. NISQA naturalness ended at 3.03, which puts it in the mixed group of our 24 recordings: the machine drops, but the voice can sound thinner.
Will EraseNoise remove a printer?
We tested a copier, not a printer. A printer makes the same kind of feed-and-print noise, so it likely gives a similar mixed result; check the free preview.
Can EraseNoise remove a printer from a live meeting?
No. It only works on a saved recording. During the meeting, use the noise suppression in Zoom, Teams, or Discord, or Krisp.
How long does EraseNoise take to clean a office recording?
Processing time depends on how long the office recording is: as a guide, a 5-minute video takes 10 to 60 seconds. The free 30-second preview of the office recording uses no paid minutes, so you can judge it first.
How large can an office recording be, and how many previews are free?
Up to 2 GB per file. You can play the 30-second preview free 3 times in 24 hours without an account, or 20 times with one. The full recording is billed per minute, rounded up, minimum 1 minute.
