# Record calls

> Record specific portions of active Vobiz calls with mp3 or wav format, optional speech-to-text transcription, and completion callback delivery.

The Record endpoint lets you start and stop recording specific portions of an active call. Create multiple recordings on the same call, choose audio formats, and enable automated transcription for compliance and quality assurance.

<Warning>
  Always comply with local recording consent laws and inform participants when calls are being recorded.

## Best practices

<Tip>
  **Use MP3 format** - MP3 files are significantly smaller than WAV, reducing storage costs and bandwidth. Use MP3 unless you need uncompressed audio.
</Tip>

<Note>
  **Transcription limits** - Transcription is available for English calls between 500ms and 4 hours, and under 2GB. Factor these limits into your design.
</Note>

<Tip>
  **Use stereo for multi-party calls** - Stereo recording separates speakers into left/right channels for easier analysis and transcription.
