How to clean a WhatsApp or Telegram voice note
- Share the voice note
In the chat, select the voice note with a long press, tap Share (in some apps it sits in the ⋮ menu) and choose Noise Remover in Android’s share sheet. The same works from your phone’s voice recorder or file manager.
- Let it clean
The cleaning starts on its own: there is no import step and nothing to set.
- Listen before you send
Switch between Original and Cleaned at the same spot. Trim a long silence at the start or the end, and lower the intensity if the voice sounds thin.
- Share it back
Tap Share, pick your messaging app and choose the conversation. The file is named after the original, with “(clean)” added.
The voice note in the chat is not changed: Noise Remover reads it and writes a separate, cleaned file, so the original is still there if you prefer it.
Noise Remover opens MP3, M4A, AAC, WAV, FLAC, OGG, Opus, AMR and 3GP files, which covers the usual sources of voice messages: Opus in OGG from WhatsApp and Telegram, M4A from most voice recorders, AMR and 3GP from older phones.

When cleaning a voice note is worth it
- A note to a client or a colleague, recorded in a car or a busy street, that should sound composed rather than rushed.
- A message to family, recorded outside in the wind or the rain.
- A memo to yourself, an idea, a list or a reminder, that you will play back later, when every word needs to be clear.
- A voice note you received and can barely make out: clean it to hear it better, without sending it anywhere.
- A recording from a phone call or a voicemail, which carries less detail to begin with: expect a cleaner sound, not a studio one.
Street noise comes up often, and Noise Remover handles it well: in our lab test at full intensity, traffic dropped by 23.8 to 37.0 dB in the speaker’s pauses and wind by 19.0 to 27.1 dB, while the voice’s own level moved by 0.1 to 0.3 dB and 0.3 to 1.3 dB respectively (how we measured).
People talking around you are another matter. Other voices are speech too, so they stay, and where they overlap yours the cleaning can turn your voice down a little with them. If your voice comes out more than 6 dB quieter than in the original, a tip suggests a lower intensity.
| Noise | Noise removed during pauses, in dB | Change in voice level |
|---|---|---|
| Traffic | 24 to 37 dB | −0.1 to −0.3 dB |
| Wind gusts | 19 to 27 dB | −0.3 to −1.3 dB |
| Rain | 15 to 20 dB | −0.3 to −0.8 dB |
| Not what it is made for | ||
| Crowd chatter | 5 to 11 dB | −0.3 to −2.8 dB |
How to record a voice note that cleans well
- Hold the phone close, its bottom edge about 10 cm (4 in) from your mouth, and keep your fingers off the microphone hole.
- Turn your back to the wind and shield the phone with your hand: the less wind reaches the microphone, the less there is to remove (see wind noise).
- Step away from people talking, since their voices stay in the recording.
- Pause a second before you speak: the rustle of the phone being raised then sits before your first word, where a trim removes it.
- For a message that matters, record it in Noise Remover, let it clean, then share the file to the chat: the noise is gone before anything is sent.
Do your voice notes leave the phone? No
Voice notes are personal: a family message, a question about your health, a word for a client. Noise Remover cleans them on the phone, with no account and nothing uploaded: the app has no server to send them to, and it works in airplane mode.
Each cleaning is kept in History on the phone, out of cloud backup, so you can reopen it, adjust it and share it again. Delete it when you are done, or clear every cleaning at once.
