Built-in recorder
Record at 48 kHz with pause and resume, a timer and a live level meter. Stop, and the cleaning starts on its own.
Features
Everything it takes to publish a clean voice
Noise Remover takes a recording from wherever it is, removes the background noise on your phone, lets you hear and adjust the result, and hands you a file ready to post.

Free · Android 8.0 or later, 64-bit
Every way in
Bring a recording in the way it already exists: no converting, no copying files around.
Import any audio file
MP3, M4A, AAC, WAV, FLAC, OGG, Opus, AMR, 3GP: pick a file with Android’s file picker. No storage permission needed.
Clean a video’s sound
Pick a video (MP4, 3GP, MKV, WebM, MOV): Noise Remover cleans its soundtrack and never touches the picture.
Share from any app
Send a voice note from WhatsApp or Telegram, or a file from your recorder or file manager, straight to the app with Android’s share menu.
Choose your microphone
Record with the phone’s own mic, a wired or USB microphone, or a Bluetooth headset, chosen in the recorder (Android 10 or later). If it disconnects mid-recording, the recording pauses.
Markers while you record
Drop a marker at any moment of a recording: it shows on the waveform of the result, to find a retake or a key line again.
Automatic cleaning, on your phone
The noise is removed on the device by an AI model made for speech, the moment your audio comes in.
AI noise removal, on the phone
A neural network made for speech separates your voice from the noise, 100 times a second, without uploading anything. No noise sample to record first.
Keeps working in the background
Leave the app while a long file cleans: a notification shows the progress and tells you when it is done. If you decline notifications, the cleaning still carries on.
Clean several files at once
Select up to 20 files and clean them one after the other, with the same settings. Save them all to one folder, or share them all in one go.
Your default settings
Choose the intensity, normalization and low-cut every new cleaning starts with. Out of the box: 80%, both on.
Compare and fine-tune
Hear exactly what changed, and decide how much of it you want.
Instant before/after
Switch between Original and Cleaned at the same moment, while it plays: no gap, no jump, so you hear exactly what was removed.
Strength slider
Choose how much noise to remove, from 0 to 100%, and hear it live. The default 80% keeps voices natural.
A tip when the voice suffers
If your voice comes out noticeably quieter than in the original, as can happen when other voices overlap, the app suggests a lower intensity.
Finish for publishing
Level, low end and length, set before you share, without a second app.
Loudness normalization
Bring the result to −16 LUFS, a ready-to-publish level, without going over −1 dB true peak. What LUFS mean.
Low-cut filter
Remove the rumble below 80 Hz (traffic, wind, handling noise) before the noise removal runs.
Trim the start and end
Drag two handles on the waveform to cut what comes before and after. Playback and export follow the range.
Export and share
Send the result where it is going, in the format it needs.
M4A export
AAC at 48 kHz and 128 kb/s: light files every app and platform accepts.
WAV, MP3 and Opus too
Export lossless WAV for your editor, MP3 for anywhere, or compact Opus on Android 10 or later.
Pro
Export the video, cleaned
Get your video back as an MP4 with its cleaned soundtrack, ready to post: the picture is copied as it is, never re-encoded, and nothing needs re-syncing in an editor.
Mono or stereo
A stereo recording stays in stereo, or can be folded to mono, which suits a single voice. A mono recording, such as one made in the app, stays mono.
Share or save
Send the file to any app from Android’s share menu, or save it to the folder you choose. Its name says what it is: “your file (clean)”.
History and storage
Every cleaning stays on your phone, ready to adjust and export again.
History of your cleanings
Every cleaning is listed by day. Reopen one to change its strength or trim and export it again: a re-export never counts against the free allowance.
Storage under control
See how much space your cleanings take, and delete the originals or every cleaning from Settings.
