Ah, very nice! I did not discover this trick yet.....
This opens new possibilities, as You suggest, for example computing the
Active Speech level according to ITU-P56 (no need for my new plugin if this
is true...).
It is even possible to get an envelope which simply switch between 0 and 1,
and which can act as a Squelch control...

Thanks!
