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 ;-)


As if I would...... ;-)

Well, all I can say is I've had nothing like it before but I've not really
done any open mic recording before either. Perhaps it's in the computer
which is a cheapjack affair with only motherboard sound atm. I'll be
considering a decent soundcard suited to this sort of thing in the near
future if it takes off. (Any recommendations?)
