You can use the threshold gate for this:

ecasound -i huge-sample.wav -o trimmed-sample.wav -ge:1,1,0

Depending on the type of silence (total, noise, ..), you may need
to play with the -ge params (see man ecasound(1)).

PS And remember to set the correct sample format with "-f" 
   if you don't want to change the audio format parameters.
