Cough or impact, two vocals

Live, the 'cough' sounded a bit like a deer cough, but they were WAY too loud.  In the recording, some of the echo from the metal roof of the porch overhead causes a bit of a metallic overtone to it that was NOT there originally.  The cough is at 1.5 to 2 seconds in, and there are two vocals, one at 11 to 11.5 seconds, and one behind a recorder noise at 12 to 12.5 seconds.
