(But not of the Media Capture TF  though that's administrativia :)

Correct, though as you can see it still needs a fair amount of work!

To be honest, I believe that much of the focus from current participants has been on the stills & video side of things so I don't know if anyone has given that much thought to multiple audio inputs. That said, the current model for video input necessarily supports multiple inputs (or rather, it supports picking one input amongst several  though I don't see why that operation could not be performed multiple times to acquire multiple feeds in parallel). Based on that, I see no reason why the same model would not apply to audio and therefore to accept multiple audio input selection.

> Chris Rogers, did I get that right?  Can we work on a scenario and some requirements for the DAP WG's Media Capture task force?  Olivier, Al, can we add this to the next Audio telcon agenda?

Scenarios would be very helpful, especially if they aren't captured in the current scenarios document.

> Robin, Dom, would it make sense for the Audio WG to also participate in that Media Capture task force?

I think that it would make a lot of sense. I don't believe that anything formal is needed for that to happen, people from the Audio WG can freely join the list and contribute  you're certainly very welcome to!
