And one  one notable difference  u u actually I can't remember whether they were going to routinely collect video or not , but one  one , uh , difference from the audio side was that they are interested in using array mikes. So , um , I mean , I 'll just tell you the party line on that. The reason I didn't go for that here was because , uh , the focus , uh , both of my interest and of Adam 's interest was uh , in impromptu situations. And we 're not recording a bunch of impromptu situations but that 's because it 's different to get data for research than to actually apply it.
Hmm.
And so , uh , for scientific reasons we thought it was good to instrument this room as we wanted it. But the thing we ultimately wanted to aim at was a situation where you were talking with , uh , one or more other people i uh , in  in an p impromptu way , where you didn't  didn't actually know what the situation was going to be. And therefore it would not  it 'd be highly unlikely that room would be outfitted with  with some very carefully designed array of microphones. Um , so it was only for that reason. It was just , you know , yet another piece of research and it seemed like we had enough troubles just
So there 's no like portable array of mikes ?
