Extract Audio from a Podcast Video (MP3 / WAV) — No Upload
Long podcast videos are easier to listen to as audio. This guide pulls the audio track losslessly into MP3 or WAV without re-encoding the video.
Step-by-step
Drop the video into Extract Audio
The tool reads the audio stream directly without decoding video — fast even for 4-hour interviews.
Pick MP3 (small) or WAV (lossless)
MP3 at 192 kbps is plenty for voice. Choose WAV if you plan to edit, then convert back to MP3 at the end.
Trim and normalize (optional)
Use the Audio Cutter to remove intros, then the Audio Normalizer to bring loudness to broadcast standards (-16 LUFS for podcasts).
Recommended settings
| Common podcast bitrate | 128–192 kbps MP3 |
|---|---|
| Apple Podcasts max | 256 kbps MP3, mono or stereo |
| Loudness target | -16 LUFS (stereo) / -19 LUFS (mono) |
| Format | MP3 (mono for voice) |
Check before you publish
- Listen to the first and last ten seconds. Extraction is lossless on the audio, so anything wrong there was wrong in the video.
- Check the level. Voice recorded through a camera mic often sits far below the -16 LUFS podcast hosts expect, and quiet uploads get skipped.
- Confirm the channel count. A mono voice track at 128 kbps sounds the same as stereo at 192 and is two thirds the size.

FAQ
Does extraction lose audio quality?
No — the tool stream-copies the source audio when possible (e.g. AAC inside MP4 → AAC out). No re-encoding, no quality loss.
Can I extract audio from a YouTube video?
Download the video first (we don't fetch from URLs). Once you have the file locally, this tool extracts the audio with no upload.
Does this run in my browser?
Yes — every step in this guide uses an in-browser FFmpeg WebAssembly tool. Your video never uploads to a server and never leaves your device.
