Sounds good - but how?

Here, "Mic1,Mic2" means the left channel captured is Mic1 and the right
channel captured is Mic2.

On the other hand, "Mic1+Mic2" means that the signals from Mic1 and
Mic2 are added together and that is captured (both as left and as right).

"Mic1" means both the left channel and the right channel captured is
from Mic1.  Likewise "Mic2".
