Audio Extractor — Get MP3 or WAV Out of Any Video
Load a video, choose MP3 or WAV, and MediaVault separates the audio track locally and hands you the file. Useful for turning an interview recording into a podcast asset, lifting a voiceover out of a rough cut, or archiving the audio from a talk.
MP3 or WAV — which to pick
MP3 is compressed and small, which suits sharing, podcast drafts and anything that will be listened to rather than edited further. WAV is uncompressed and much larger, which is what you want if the audio is going into an editor for further processing.
Why extraction should be local
Audio is where the sensitive part of most recordings lives — the conversation itself. Interviews, client calls, therapy sessions and internal meetings are exactly the material that should not be handed to a conversion site in exchange for an MP3.
How to use it
- Load the video. Open the Audio Extractor and select any video file.
- Choose your format. Pick MP3 for a small shareable file or WAV for further editing.
- Extract and download. The audio track is separated locally and saved to your device.
Frequently asked questions
Does extracting audio reduce quality?
Choosing WAV preserves the audio as-is. MP3 re-encodes it, which is lossy but generally transparent for speech and fine for most listening.
What video formats are supported?
MP4, MOV, MKV, WebM, AVI and the other common containers FFmpeg handles.
Is my video uploaded?
No. Extraction happens in your browser and the file never leaves your device.
