Hi, I always put a [env] to gate the sigmund data ouput. Whenever [env] gets below a certains level (basically that of your noise), you use a [ > X] to output a binary number (0 when it goes below X), which then controls a [spigot], which blocks the data flowing from sigmund. The only tricky part is to tune this to the right noise level.

hi, I'm using sigmund~ to get sound input from microphone(with adc~), the data is controling the movement of gem objects. But it seems that the sigmund~ respond to silence as well and react in a constant change of the data. Is there a way to control this noise?
Depends on the 'noise' and what is producing it. Ideally you should first of all try to achieve the best signal:noise ratio for the signal you want to use to feed sigmund~. After which you might try some sort of gating, depending on the source type (you talk about silence so you could look at e.g. at [threshold~] or [env~]) and application.
