How to extract audio from a video on Mac (to MP3)
Updated 2026-06-11 · Runs locally — nothing uploaded
Need just the sound from a video — an interview, a lecture, a song from a clip? You don’t need an editor or an upload site to pull it out.
FFmix’s one-click Video → MP3 320k preset drops the video track and writes a high-quality MP3 next to the original — locally, so the file never leaves your Mac. For a lossless hand-off, it can export WAV instead.
Steps
- 1 Drag your video into FFmix.
- 2 Pick the Video → MP3 320k preset (or the Extract audio task).
- 3 Confirm and click Start — the .mp3 saves next to the video.
Advanced: the real ffmpeg command
This is exactly what FFmix runs. Copy it, tweak it, or just use the one-click preset.
ffmpeg -i input.mp4 -vn -c:a libmp3lame -b:a 320k audio.mp3Drop a file and go — all local, nothing uploaded.
FAQ
What quality is the MP3?
320 kbps by default, which is effectively transparent for speech and music. You can drop to 192 kbps for a smaller file, or export WAV for a lossless master.
Can I extract audio from any video format?
Yes — MP4, MOV, MKV, WebM and more. FFmix reads the file with the bundled ffmpeg engine and writes a clean MP3.
Is the video uploaded anywhere?
No. The audio is extracted locally on your Mac; nothing is uploaded.
