Had it built by a private investigator, Hal Lipset, who is
unfortunately no longer alive. He's the same fellow on whom aspects
of the Francis Ford Coppola movie, "The Conversation," was partially
based. In the late 60s he developed a microphone that fit in a
martini olive so that he could record conversations of a suspect at a
party. Mine was based on that system only 15 years later, it was much
smaller and more powerful. I occasionally worked with Lipset in the
field of audio forensics realted to a few of his cases. There are
some books about and by him if you want to get momentarily diverted
like Bug in the Martini Olive and Other True Cases from the Files of
Hal Lipset, Private Eye by Patricia Holt, and others.
The very low level ultrasound body sounds can mostly be found in the
viruses that live in the body and which have been recorded by
researchers (and published) living and working in the UK. You won't
be able to get them with available technology as it requires very
special equipment. I'll provide references on request if you want
them.
