/*
Envelope subsystem for applying linear interpolated volume
envelopes on audio data. If multiple enevelopes shall be applied
at the same time, the "minimum" envelope is determined and
applied.
Envelopes are defined in a statically allocated constant structure
pa_envelope_def. It may be activated using pa_envelope_add(). And
already active envelope may be replaced with pa_envelope_replace()
and removed with pa_envelope_remove().The combined "minimum"
envelope can be applied to audio data with pa_envelope_apply().
_apply() on one hand and _add()/_replace()/_remove() on the other
can be executed in seperate threads, in which case no locking is
used.
