<DIV><FONT face=Arial size=2>Hi all !</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>How Speex VAD works? I mean, what kind
of <FONT face=Verdana>algorithm is used? It uses dynamic
threshold?</FONT></FONT></DIV>
<DIV><FONT face=Verdana size=2>I'm testing the VAD function with some
computers/microphones and it is working only when the silence is
sampled with values near zero (around -50 ~ 50). </FONT></DIV>
<DIV><FONT face=Verdana size=2>With some microphones (and with some computers
too) silence is sampled with noise values like 150 ~ 200, or -300 ~ -250.. and
VAD just don't work (silence isn't detected). </FONT></DIV>
