Body: <p>I livestream video game tournaments. The videos I record have two audio tracks. The first track is a low-volume game sound, combined with commentary audio. The second track is just the normalized volume game sound.</p>
  
  <p>When I upload this video to YouTube, what is going to happen? Will YouTube combine both audio tracks into a single track? Will it throw out track 2?</p>
  
  <p>Has anyone done this before?</p>

  Youtube will encode the primary or default audio stream.
  
  Youtube doesn't support multiple audio [streams](https://productforums.google.com/forum/?hl=en#!topic/youtube/OtzjKBksQAo;context-place=topicsearchin/youtube/multiple$20audio). Neither does [Vimeo](https://vimeo.com/forums/topic:107372).

  Good news at the horizon. You should expect [Multi-audio tracks and descriptive audio feeds](https://support.google.com/youtube/thread/129769858/updates-to-captions-and-audio-features-on-youtube?hl=en#:%7E:text=Multi-audio%20tracks,the%20coming%20quarters.) support in the near future. There's actually a [video demo](https://youtu.be/WaOKSUlf4TM) with this capability, which is kind of proof of concept.
