I didn't mean that it was recorded with an ordinary microphone.  I was
played it in a lecture, so unless either my lecturer or the sleeve notes
were wrong, what I say is apparantly true.

I don't know what kind of hardware one needs for something like this - I
don't think anyone thought there'd be much sense out of the built in laptop
mic.

Just to carry on my defensive tack, perhaps I could have made myself
clearer:

One certainly would need something specialized; I don't know anything about
infrasonic mics (and I don't have time to google it now), but I suspect that
if one did have the appropriate transducer to pick up the desired
frequencies, plugging it straight into the laptop's mic in would be a bit of
a no-no.  I don't know how these things interface.

I do know that logic (or any software)'s dynamic range would not be the
limiting factor.
