This is not currently possible, so a new gate type needs to be added.
Fortunately this isn't that difficult. If you look at the code of current
ecasound gates (ecasound/libecasound/audiogate.cpp), it is quite
straightforward (all gate related code is under 200 lines of C++).
PS I read through the related thread on linux-audio-dev. As
mentioned there, LADSPA plugins cannot provide similar functionality
as they can't drop samples like ecasound's gate operators can.
