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.
The most common case is pulling an MP3 out of an MP4 — a screen recording, a downloaded clip, a meeting export — and it’s the same single click on any Mac or MacBook. MOV, MKV and WebM work exactly the same way.
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.

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.
How do I extract just the MP3 from an MP4 on Mac?
Drop the .mp4 into FFmix, pick Video → MP3 320k, and confirm — a clean .mp3 saves next to the original, no command line and nothing uploaded. The same single click works on any Mac or MacBook, and for MOV, MKV or WebM files too.
Is the video uploaded anywhere?
No. The audio is extracted locally on your Mac; nothing is uploaded.
