And  and the acoustic people will always say , " well are you doing , uh , uh , array microphones ? " So it 's  it 's a good thing to do , but it doesn't solve the problem of how do you solve things when there 's one mike or at best two mikes in  in this imagined PDA that we have. So maybe  maybe we 'll do some more of it.
Well one thing I  I mean , I don't know. I mean , I know that having an array of  I mean , I would imagine it would be more expensive to have a  an array of microphones. But couldn't you kind of approximate the natural sis situation by just shutting off uh , channels when you 're  later on ? I mean , it seems like if the microphones don't effect each other then couldn't you just , you know , record them with an array and then just not use all the data ?
It 's  it 's just a lot of infrastructure that for our particular purpose we felt we didn't need to set up.
I see.
