Sounds sorta like a large transient 'pulse' incoming from maybe local
switching thats putting an overly large signal onto your recording thats
depressing an autogain control circuit - the waveform coming up in 1/4

sec
is the recovery time. Thats guessing mind....



Ok, I'll buy that - presumably the 'autogain control circuit' is in the

mic,
Mike? (New component, new phenomenon....) But why/how is the waveform

pulled
down from the 'centreline' or is that just a 'software thing'?


Its not the mic, it looks more like the recovery of an amplifier circuit
thats had a sudden and gross overload - like walking into a wall when ****ed
and the time taken after to realise what happened ;-)
