Description
Add support for gated measurement
Measurement would be more useful for anything other then music (such as dialogs in movies) when gated measurement will be added.
I don't think something like gated measurement defined in EBU – TECH 3342 will fit this filter. Simple gate would be enough. Measure only if signal exceeds predefined fixed level. In this kind of metering gated silence will not be responsible for lowering integrated RMS loudness.
So I think two settings should be added
- gate level in DB - when volume is bellow this level start closing gate. Closing gate will not change output signal. Input will be still measured and stats updated.
- gate close time in sec - after gate is fully closed, stop using input data for volume computations until gate opens again.
- I am not sure if there is need for gate open time - pro VST3 measurement plugins are implementing open gate time defaulting to 4 ms.

astats is not place for this functionality at all.
Better in another filter, if at all.
