The estimation on how well the linear filter in the AEC3 is performing
is done through an estimation of the ERLE. That estimation is then
used for knowing how much the suppressor needs to react in order to
cancel all the echoes.
In the current code, the ERLE is quite conservative during farend
inactivity and it is common that it goes to a minimum value during
those periods. Under highly varying conditions, that is probably the
right approach. However, in other scenarios where conditions does not
change that fast there is a loss in transparency that could be avoided
by means of a different ERLE estimation.
In the current CL, the ERLE estimation has been changed in the
following way:
- During farend activity the ERLE is estimated through a 1st order AR
smoother. This smoother goes faster toward lower ERLE values than to
larger ones in order to avoid overestimation of this
value. Furthermore, during the beginning of the farend burst, an
estimation of the ERLE is done that aim to represent the performance
of the linear filter during onsets. Under highly variant environments,
those quantities, the ERLE during onsets and the one computed during
the whole farend duration, would differ a lot. If the environment is
more stationary, those quantities would be much more similar.
- During nearend activity the ERLE estimation is decreased toward a
value of the ERLE during onsets.

We want to know how the AudioMixer is used and how FixedGainController
behaves.
The WebRTC.Audio.Agc2.FixedDigitalGainCurveRegion.* metrics measures
how often the input level hits different regions of the Fixed Gain
Controller gain curve (when the limiter is enabled). They also measure
how long the metrics stay in different regions. They are related to
WebRTC.Audio.ApmCaptureOutputLevelPeakRms, but the new metrics measure
the level before any processing done in APM.
The AudioMixer mixes incoming audio streams. Their number should be
mostly constant, and often some of them could be muted. The metrics
WebRTC.Audio.AudioMixer.NumIncomingStreams,
WebRTC.Audio.AudioMixer.NumIncomingActiveStreams log the number of
incoming stream and how many are not muted. We currently don't have
any stats related to that.
The metric WebRTC.Audio.AudioMixer.MixingRate logs the rate selected
for mixing. The rate can sometimes be inferred from
WebRTC.Audio.Encoder.CodecType. But that metric measures encoding and
not decoding, and codecs don't always map to rates.
