# About Audio Tracks

When capturing and recording, you can transfer one video track and up to 16 audio tracks (eight tracks of DVS/AJA AES audio, or 16 tracks of embedded AJA audio). In Lustre, audio tracks are identified as A1 through A16. You can select non-consecutive tracks (for example, you can select tracks A1, A5, and A8).

You can capture, playback, and play out audio in two different ways:

- Audio embedded with video, coming from or going to the SDI connectors ('Embedded' option)
- Audio going through XLR cables from or to the DVS or AJA breakout box ('AES' option)
