### Converting Recordings to WAV

Use FFmpeg to convert raw PCM files to WAV format:

```bash BASH theme={null}
# Convert user audio
ffmpeg -f s16le -ar 16000 -ac 1 -i user.raw user.wav

# Convert agent audio
ffmpeg -f s16le -ar 16000 -ac 1 -i agent.raw agent.wav

# Convert interleaved audio
ffmpeg -f s16le -ar 16000 -ac 2 -i interleave.raw interleave.wav
```
