[PD] sigzero~

[Alex]

Hi there,

I am using sigzero~ to detect the start of a sound from the file I am 
playing. It works fine.
However, the file in question is a stream from shoutamp~ and the start 
of the stream produces some very little white noise at around -40db 
that sigzero~ detects to be the start of the file.
Is there a way to change the threshold of sigzero~ in the source maybe, 
or does anyone think of any other solutions  ?
Thanks
