I used to build voice scramblers, but mostly in hardware using
a Psuedo noise source. It wirked pretty good, but had to
compress the bandwidth down to about 2kHz. Thus the reason
why it sounds like talking in a tunnel. Has anyone done a
feasability study on whether of not a 486 or Sparc station can
do this in real time?
It would seem to me that Voice mail systems should incorperate
this in their system, thus scrambling the messages unless a
access code can be used to retrieve it.
