A video audio extractor pulls the audio track out of a video file.
This first browser-side version exports M4A/AAC or WebM/Opus from videos under 200MB.
Videos with audio
The source must include an audio track for extraction to succeed.
Short clips
Smaller files finish faster and are more reliable in browser memory.
Example
Upload a short MP4 interview, choose M4A output at 128 kbps, and download the extracted audio track.
Assumption
The video contains at least one audio track and is under 200MB.
Limitation
This tool does not separate speakers, remove noise, transcribe speech, or preserve multiple audio tracks as separate files.
Podcast prep
Pull audio from a recorded video conversation.
Voice notes
Extract spoken audio from a screen recording.
Editing handoff
Create an audio-only file for review or further editing.
