Implementations may be doing several things to improve quality, like echo cancellation, synthesizing samples to conceal packet loss, and noise suppression. Strategies are, however, implementation-specific. This can make standardizing metrics around it difficult.

We could add a metric to say that this is the implementation's estimate of the current background noise levels. But different implementations may do different things to attempt to calculate this, which could potentially yield different numbers in different scenarios.

This reminds me the attempt to standardize [likelihood of echo](https://github.com/w3c/webrtc-stats/issues/153) which got ice boxed.

But hey, an experimental metric might be better than no metric, even if we can't yet guarantee interoperable estimates?
