How to extract audio from a video without software
Received a conference recording in MP4, an interview in MKV, or a tutorial you want to keep as audio only? No need to install VLC, Audacity or ffmpeg on your machine.
Why extract audio from a video?
There are many good reasons:
- Homemade podcasts: turn a Zoom meeting recording into an audio file you can listen to on the go.
- Background music: extract the soundtrack from a video (with appropriate rights).
- Transcription: get a lighter audio file before feeding it to a speech recognition tool.
- Storage savings: a 5 MB MP3 vs. a 300 MB video — that's a big difference.
