Audio Extract
Extracts the audio track from a video file. This is a local operation using the bundled ffmpeg binary - no API keys or external services required.
Command
npx agent-media@latest audio extract --in <path> [options]
Inputs
| Option | Required | Description |
|--------|----------|-------------|
| --in | Yes | Input video file path or URL (supports mp4, webm, mkv, avi, mov) |
| --format | No | Output audio format: mp3 (default) or wav |
| --out | No | Output path, filename or directory (default: ./) |
Output
Returns a JSON object with the extracted audio file:
{
"ok": true,
"media_type": "audio",
"action": "extract",
"provider": "local",
"output_path": "extracted_123_abc.mp3",
"mime": "audio/mpeg",
"bytes": 24779
}
Examples
Extract audio as MP3 (default):
npx agent-media@latest audio extract --in video.mp4
Extract audio as WAV:
npx agent-media@latest audio extract --in video.mp4 --format wav
Custom output directory:
npx agent-media@latest audio extract --in video.mp4 --out ./audio-files
Use Case: Video Transcription Workflow
Since transcription services work best with audio files (smaller uploads, faster processing), use this workflow:
# Step 1: Extract audio from video (local, instant)
npx agent-media@latest audio extract --in interview.mp4 --format mp3
# Output: extracted_xxx.mp3
# Step 2: Transcribe the audio (cloud API)
npx agent-media@latest audio transcribe --in extracted_xxx.mp3 --provider fal
Provider
This action uses the local provider with bundled ffmpeg (via ffmpeg-static). No API keys required.
