The AdaptiveAgc often boosts the signal outside of Float S16 range. It is expected, which is why we have a limiter after it in the process chain. But it turns out that this happens regularly even for simple input examples. The output signal peaks can be as high as +4 dBFs for a single speaker example (which should be easy). It leads to excessive gain modulation by the limiter. This CL is a new tuning designed to produce a safer gain. After this, we shouldn't hit the saturation region of the limiter as often. But we will still maintain a high gain. We have a 'configurable kill-switch': the settings can be changed via field trials WebRTC-Audio-Agc2Force(Initial|Extra)SaturationMargin.
