I guess the closest thing in ecasound is this:

"""
-ge:open-threshold-%, close-thold-%,volume-mode

  Threshold gate. Initially gate is closed. It is opened when volume  goes over 'othreshold' percent. After this, if volume drops below 'cthold' percent, gate  is  closed  and  won't  be  opened again.   If  'value_mode'  is 'rms', average RMS volume is used.  Otherwise peak average is  used.   When  closed,  passing audio buffers are trucated to zero length.
