How do I check a door slam before I pay?
Let the door recording play and flip between the raw take and the cleaned one at the slam. Then upload your file and go straight to the moment the door hit.
The door recording started with one of the lowest naturalness scores of the 24 we tested, 0.95, and ended at 4.05. Overall quality went from 1.82 to 2.80 and background from 2.17 to 4.02. A creaking chair, another short knock-and-creak sound, is next to it. Scores are DNSMOS and NISQA predictions on a 1–5 scale for real door-slam and related recordings from the Microsoft DNS Challenge test set, processed with no hand edits.

Which door sounds can be removed?
A door is short and loud. It drops best between words, and a slam on top of a word may leave that word rough.
A door slam in the next room
Someone came home during the take. The slam drops, and the voice around it stays.
Hear the recordingKnocking
We have not tested knocking on its own. Knocks are short bursts like the slam we did test, so check one in the free preview.
A creaking hinge
We have not tested a hinge. A slow creak is close to the creaking chair we did test, where naturalness went from 3.01 to 4.59.

The slam drops, but the word under it can sound clipped. Listen to that word in the preview.
Why remove door noise with EraseNoise?
A slam is one loud peak. Cutting it out by hand works once; EraseNoise handles every one in the file.
No hunting for each slam
You do not scrub the timeline for every door. Upload the file once.
The timing stays
Nothing is cut, so the recording keeps its length and stays in sync with the video.
A real sample to judge
Hear the door recording above before you upload anything.
Why not just cut the slam out?
Cutting works when the door hits in a pause.
A slam over a word
Cutting removes the word too. A cleanup lowers the slam and keeps the word.
Video in sync
A cut in the audio shifts the lips out of sync. The cleanup keeps every frame where it was.
EraseNoise vs other ways to remove a door slam
A slam is one loud peak, so the right fix depends on where it lands.
| Option | Works best when | Falls short when |
|---|---|---|
| EraseNoise | Doors slam several times through a long take | A slam lands right on a word you need |
| Audacity Noise Reduction | Rarely: it is built for steady noise | The noise is a single sudden bang |
| Cutting in an editor | One slam falls in a pause in audio-only work | Cutting a video track throws the lips out of sync |
| Re-recording the line | The slam covered the key sentence | The interview or lecture cannot be repeated |

Frequently asked questions
How do I remove a door slam from audio?
Put the file with the slam into the uploader at the top of the page and listen to the free 30-second before-and-after. Download the full file only if the slam is lower and the words around it are clear.
How well does EraseNoise remove door noise?
On a real door-slam recording from the Microsoft DNS Challenge test set, EraseNoise raised NISQA naturalness from 0.95 to 4.05 out of 5, from one of the lowest starting points of the 24 recordings we tested. The DNSMOS background score went from 2.17 to 4.02 and overall quality from 1.82 to 2.80.
Can a slam on top of a word be removed?
The slam drops, but the word under it can sound rough. If that word matters, a retake of that line is the safe fix.
Will EraseNoise remove knocking?
We tested a door slam, not knocking. Knocks are short bursts like a slam, so they likely drop the same way; check one in the free preview before you pay.
Can EraseNoise remove a door slam during a live call?
No, only from a recording that has finished. While the call is running, turn on noise suppression in Zoom, Teams, or Discord, or use Krisp.
How long does EraseNoise take to clean a recording with a door slam?
Processing time depends on how long the recording with a door slam is: as a guide, a 5-minute video takes 10 to 60 seconds. The free 30-second preview of the recording with a door slam uses no paid minutes, so you can judge it first.
How big can the file be, and how often can I preview a slam for free?
Up to 2 GB per file. The free 30-second preview can be played 3 times per 24 hours signed out and 20 times signed in. The full clean costs whole minutes, rounded up, with a 1-minute minimum.
