Video Audio Extractor
Pulls the audio track out of videos and saves it as MP3, WAV, FLAC or M4A.
What it does
Use this to turn webinars into podcasts, rip music from films/series, or archive only the audio from interview videos.
Note: This is the same job as the Video to Audio Extractor in the audio_engine module. Either one works.
How to use
- Drag video files into the list.
- Pick an Output Format: MP3, WAV, FLAC or M4A.
- Pick an Audio Bitrate (default 320 kbps).
- Click Run.
You get one audio file per video.
Supported video formats
MP4, MKV, AVI, MOV, FLV.
Picking a format
| Format | What for |
|---|---|
| MP3 | Most universal, every device plays it. |
| WAV | Uncompressed, for professional editing. |
| FLAC | Lossless compression, archive-quality. |
| M4A | Apple devices, AAC format. |
Bitrate
- 320 kbps: High quality, for podcasts or music.
- 256 kbps: High quality, balanced size.
- 192 kbps: Standard quality.
- 128 kbps: Slight quality drop, small files.
Examples
Webinar into a podcast: Add the webinar MP4, MP3 192 kbps, run. Listenable audio file.
Pull music from a film: Add the MKV, MP3 320 kbps, run.
Archive a meeting's audio: Add the MP4s, FLAC, run. Lossless archive.
Audio from a clip: Add the MP4 clip, M4A, run. Usable on iPhone.
Watch out
- Bitrate higher than the source quality does not improve it.
- For videos with multiple audio streams (like MKV) only the first one is taken.
- DRM-protected or encrypted videos cannot be processed.
- Very large videos take minutes.
