Re: [webrtc-stats] Measuring background noise (energy) (#465)

I think that the hard part for a standardized metric for background noise
is defining what part of the signal is background and what part is not. We
do have a background noise estimate in the gain controller, but if we were
to standardize how it's computed we won't be able to easily make
changes/improvements (without adding unnecessary additional computations).

Would it be an option to have a background noise metric without specifying
how to decide what part of the signal is background?
