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
shooting off the top of my head here, but did you experiment with amplifying the signal before it going into [sigzero~] ?

also maybe you would have more control by just watching the output of env~?

i don't think that this will work, as [sigzero~] *really* detects whether a signal is zero (all zero!) or not.
i used it to switch on/off a [switch~] when no signal was present.
but for you a solution with [env~] might work.
