How do I check the extracted audio before I save it?
Extract audio from video, then play the result on this page before you download it. The file is read and written by your browser, so the video never leaves your phone or computer, and there is nothing to wait for on a server.
Play it here first
A player appears under the download button. Skip to a few places and listen for the start, the middle, and the end.
See whether it was re-encoded
The result says whether the audio track was copied as it is or converted. A copied track is the exact sound the camera recorded.
Why do people extract audio from video?
Most of the time the picture is not needed. You want the voice, the music, or the soundtrack on its own, as a file another app can open.
Clean the voice in another tool
Noise removal, transcription, and podcast editors work on audio. Extract the soundtrack, clean it, and lay it back under the picture.
Remove background noise from audioTurn a talk into a podcast episode
A recorded webinar, lecture, or Zoom call becomes an audio file people can play on a walk.
Send a transcript service just the sound
An audio file is a fraction of the size of the video, so it uploads faster to a transcription tool.
Keep a voice memo from a clip
A phone video of a toast, a lesson, or an interview can be kept as audio when the shot itself does not matter.
Which format should I pick when I extract audio from video?
Pick M4A unless you have a reason not to. Phones and most cameras record AAC sound, and M4A keeps that track exactly as it is.
| M4A | MP3 | WAV | |
|---|---|---|---|
| What happens to the sound | An AAC track is copied with no re-encoding. Other tracks are converted to AAC. | Converted to MP3 at 192 kbps, unless the track is already MP3 | Decoded to uncompressed PCM |
| File size for 10 minutes | About the size of the original soundtrack | About 14 MB | About 100 MB in stereo at 44.1 kHz |
| Best for | Keeping the exact sound, and Apple apps | Playing on any device or uploading anywhere | Editing, mixing, and noise removal |
| Length limit | None beyond the 2 GB video | None beyond the 2 GB video | 60 minutes, because WAV is built in memory |
Why extract audio from video with EraseNoise
It does one job: take the soundtrack out of a video file and hand it back to you, with nothing added.
Nothing is uploaded
Your browser reads the video and writes the audio file. A private recording stays on your device, which most online converters cannot say.
No re-encoding when it is not needed
An AAC soundtrack goes into the M4A untouched, so there is no generation loss. Only MP3 and WAV, or a non-AAC track, are converted.
Free with no account and no watermark
There is no sign-up, no daily cap, and no audio tag. The work happens on your device, so it costs EraseNoise nothing to run.
Large videos are fine
Only the audio packets are read, so a 2 GB 4K video does not have to fit in memory. The picture is skipped, not decoded.
Why is it faster than an online converter?
There is no upload and no queue. Extracting audio from video here takes about as long as reading the file from your disk.
No upload wait
A 1 GB video does not have to travel to a server and back. Copying an AAC track into M4A usually finishes in seconds.
Works on a phone
Open the page in Safari or Chrome on your phone, pick the video from your library, and save the audio to Files.
No editor to open
You do not need a project, a timeline, or an export dialog to get the sound out of one clip.
Which videos can I extract audio from?
Extract audio from video files up to 2 GB. Audio files work too, if you only want to change the format.
MP4, MOV, M4V, or WebM
This covers iPhone and Android video, GoPro and most cameras, screen recordings, and most downloads from editors. The video needs a sound track.
MP3, WAV, M4A, AAC, OGG, Opus, or FLAC
An audio file can be converted to M4A, MP3, or WAV here. That is handy when an app only accepts one format.
MKV from OBS
Remux it to MP4 first in OBS with File, Remux Recordings. That takes seconds and does not touch the picture or the sound.
Files you are allowed to use
This page works on video files already on your device. It does not download from YouTube, TikTok, or any other site.

Where extracting audio from video helps
A vlog with a noisy voice
Extract the WAV, clean the street or cafe noise out of it, and put the clean track back under the clip in your editor.
A webinar turned podcast
Save the recording as MP3, trim the start, and publish it as an episode. Normalize it to -16 LUFS so it plays at a podcast level.
A lecture for transcription
Send an M4A instead of a 2 GB video. The transcript tool gets the same sound at a fraction of the upload size.
What to do after you extract audio from video
Most extracted soundtracks need one more step. Each of these runs on its own page.
| Job | Use |
|---|---|
| Wind, fan, traffic, or hum under the voice | Remove background noise from audio |
| The voice is too quiet, or levels jump between files | Normalize audio (free, in the browser) |
| Long pauses | Remove silence from audio (free, in the browser) |
| Clean the voice and keep it in the video | Remove background noise from video, with no extract step |
| Music under someone talking | Remove background music |
Does the video get uploaded?
No. To extract audio from video, EraseNoise reads the file in your browser and writes the audio file there too. No copy is sent to a server or stored, so refreshing the page clears the result. Download it before you leave.
Frequently asked questions
How do I extract audio from a video for free?
Open this page, choose the video, pick M4A, MP3, or WAV, and select Extract audio. The browser does the work, so it is free, needs no account, and adds no watermark.
Is my video uploaded?
No. The video is read and the audio is written by your browser. Nothing is sent to EraseNoise or anyone else.
Does extracting audio lower the quality?
Not with M4A when the video has AAC sound, which is what phones and most cameras record: the track is copied without re-encoding. MP3 is re-encoded at 192 kbps. WAV is lossless, but it cannot add back detail the camera did not record.
Can I convert MP4 to MP3 here?
Yes. Choose the MP4 and pick MP3. The soundtrack is encoded at 192 kbps in your browser, and the picture is left out.
Can I extract audio from a YouTube video?
Not from a link. This page only works on video files already on your device that you have the right to use. It does not download from YouTube or other sites.
Will the extracted audio stay in sync with the video?
Yes. The audio keeps its own timing, so it lines up when you place it at the start of the clip. If you clean it and put it back, keep it the same length and start it at the first frame.
