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) |
Quality check before publishing
- Play the first and last three seconds to catch bad trims, black frames, missing audio, or a visible jump at the end.
- Confirm the exported file matches the important settings above, especially duration, aspect ratio, resolution, codec, and file size.
- Preview once on the target platform or device before deleting the original source file.
- If the clip will be reposted publicly, strip metadata first and verify no private names, GPS data, or device fingerprints remain.

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.
