Clean up a voice memo.
Recorded a voice memo on your phone somewhere noisy? Upload it and the background noise and echo come out.
From your phone to clean audio
On iPhone, open Voice Memos, tap the recording, tap ••• and choose Save to Files. Then tap Choose a file on this page and pick it. The file is an M4A, which works as it is; most Android recorders save M4A or MP3, which work too.
Phone microphones pick up everything around them: traffic, the café, the room itself. BackMute removes the steady part of that noise and reduces echo, so the voice is easier to understand.
How it works
Any phone or laptop recording up to 100 minutes.
Fans, traffic, hum and hiss go. Echo from bare rooms is cut down.
Compare before and after, then save the MP3.
Questions
How do I remove background noise from a voice memo?
Upload the memo on this page and press Clean audio. About a minute later you can compare before and after and download the cleaned MP3.
Can I do it on my phone?
Yes. The page works in Safari and Chrome on iPhone and Android: tap Choose a file and pick the recording.
Is my voice memo kept?
No. It is cleaned on our server and sent back to you. Neither the upload nor the cleaned copy is kept.
