# Audio Extractor

Extracts audio from video files to WAV format for further analysis. Converts to mono 16kHz PCM format optimized for speech/energy analysis.

## Use Cases

- Extracting audio for speech analysis
- Preparing audio for energy calculation
- Converting video audio to standard format

## Usage

```bash
python3 /root/.claude/skills/audio-extractor/scripts/extract_audio.py \
    --video /path/to/video.mp4 \
    --output /path/to/audio.wav
```

### Parameters

- `--video`: Path to input video file
- `--output`: Path to output WAV file
- `--sample-rate`: Audio sample rate in Hz (default: 16000)
- `--duration`: Optional duration limit in seconds (default: full video)

### Output Format

- Format: WAV (PCM 16-bit signed)
- Channels: Mono
- Sample rate: 16000 Hz (default)

## Dependencies

- ffmpeg

## Example

```bash
# Extract first 10 minutes of audio
python3 /root/.claude/skills/audio-extractor/scripts/extract_audio.py \
    --video lecture.mp4 \
    --duration 600 \
    --output audio.wav
```

## Notes

- Output is always mono for consistent analysis
- 16kHz sample rate is sufficient for speech analysis and reduces file size
- Supports any video format that ffmpeg can read
