How to Extract Audio from a Video on Android (MP3 or M4A, Step by Step)
You recorded a video on your Android phone, or saved one from a chat, and you only want the sound: a voice memo, a lecture, a song idea, an interview answer, or a clip for a podcast. Android doesn't have one universal "save audio only" button the way some people expect, but there are reliable ways to extract audio from a video on Android without a computer.
This guide covers four methods, from quickest to most powerful, plus how to skip the audio file entirely when what you really want is the words.
Quick answer
- Want an audio file in a minute? Use a reputable video-to-audio converter app or a browser-based converter (Method 1 or 2).
- Want full control and no ads? Run FFmpeg on your phone with Termux (Method 3).
- Want the text of what was said? Skip the audio step and transcribe the video directly (Method 4).
Before you start: MP3, M4A, or WAV?
Most Android phones record video with AAC audio inside an MP4 file. That gives you a choice:
- M4A (AAC): pulls the existing audio track out with no re-encoding, so there's no extra quality loss and the file is small. Best default.
- MP3: plays everywhere, but converting from AAC re-encodes the audio, so pick a high bitrate (192 kbps or more).
- WAV: uncompressed and large. Only useful if you're about to edit the audio heavily.
More detail in MP3 vs WAV for extracted audio and extracting audio without losing quality.
Method 1: Use a video-to-audio converter app
The Play Store has many "video to MP3" apps. They work, but quality varies a lot. When choosing one:
- Check permissions. A converter needs access to your media files. It doesn't need your contacts, location, or SMS.
- Look for a bitrate or "original quality" option. Avoid apps that only export low-bitrate MP3.
- Prefer apps that convert on the device. Some upload your video to a server first, which is slow and a privacy concern for personal recordings.
Typical flow: open the app, pick the video from your gallery, choose MP3 or M4A, optionally trim the start and end, then export. The audio usually lands in your Music or the app's own folder, which you can find in the Files app.
Method 2: Use a browser-based converter
If you don't want to install anything, open Chrome and use an online video-to-audio converter:
- Open the converter site and tap upload or choose file.
- Pick the video from your gallery or Files.
- Choose the output format (M4A or MP3) and convert.
- Download the result. It saves to your Downloads folder.
Best for: short clips on Wi-Fi. Avoid for: long or private recordings, because the whole video is uploaded to someone else's server.
Method 3: Use FFmpeg on Android with Termux (most control)
FFmpeg is the free, open-source tool most converters use under the hood. You can run it on Android through Termux, a terminal app (install it from F-Droid or its official GitHub releases).
- Open Termux and install FFmpeg:
```
pkg update && pkg install ffmpeg
termux-setup-storage
```
termux-setup-storage asks for permission to read your shared storage. Your camera videos are usually in ~/storage/dcim/Camera.
- Extract the audio without re-encoding (fastest, no quality loss):
```
ffmpeg -i ~/storage/dcim/Camera/VID_20261006.mp4 -vn -c:a copy ~/storage/music/clip.m4a
```
- Or convert to MP3 if you need it for compatibility:
```
ffmpeg -i ~/storage/dcim/Camera/VID_20261006.mp4 -vn -c:a libmp3lame -q:a 2 ~/storage/music/clip.mp3
```
Replace the file name with your own video. -vn drops the video, -c:a copy keeps the original audio untouched, and -q:a 2 is a high-quality variable bitrate for MP3.
It looks technical, but once it's set up it's the fastest and most private method: nothing leaves your phone, and there are no ads or watermarks.
Method 4: Skip the audio file and get the text
A lot of people extract audio only as a step toward something else: notes from a lecture, quotes from an interview, captions for a reel, or a transcript of a voice message. If that's you, you can go straight from video to text:
- Upload the video from your phone to SkyScribe, or paste a link if it's on YouTube, TikTok, Instagram, or X.
- Get a timestamped transcript.
- Copy the text, or export SRT captions for your video editor.
This saves a conversion step and avoids juggling audio files. The audio to text tool also works if you already extracted an M4A or MP3 using one of the methods above.
Troubleshooting
- The extracted file is silent. The video may have no audio track, or the app exported the wrong stream. Play the original video with sound first to confirm.
- "Unsupported format" when copying audio. Some videos use audio codecs that can't go straight into M4A. Convert to MP3 instead (Method 3's second command).
- Audio is out of sync with your edit. Extract from the final exported video, not the original recording.
- The file is huge. You probably exported WAV. Use M4A or MP3 unless you need uncompressed audio.
- Can't find the file. Open the Files app and check Downloads, Music, or Audio, or search by the time you exported it.
On iPhone instead?
The steps are different on iOS. See our guide to extracting audio from a video on iPhone with no apps.

FAQ
Can I extract audio from a video on Android without an app?
Yes. Use a browser-based converter in Chrome, though it uploads your video to a server. For no app and no upload, Termux with FFmpeg is the most private option.
What's the best format for extracted audio on Android?
M4A in most cases, because it keeps the original AAC audio without re-encoding. Choose MP3 if the destination only accepts MP3.
Does extracting audio reduce quality?
Not if you copy the original stream (M4A). Converting to MP3 re-encodes it, which loses a little quality, so use a high bitrate.
Can I extract audio from a WhatsApp or Telegram video?
Yes. Save the video to your phone first, then use any method above. Find it in Files under the app's media folder.
How do I turn the audio into text?
Upload the audio or the original video to a transcription tool such as SkyScribe and copy the transcript or export SRT.
