<DIV><FONT face=Arial size=2><SPAN class=616163310-16072002>I would like to use
a sound card input as a voice key (i.e. detect the onset of a sound). I have
already used hardware voice keys (which close a contact, read by the parallel
port), but now I need more and as all our PCs already have a soundcard
(SoundBlaster PCI-128's) I was hoping someone could suggest how to do
this?</SPAN></FONT></DIV>
