Assigning these all to you, since it looks like you reported them and they're about AEC3. Untriaged needs to get triaged. :)

AEC3: Decrease latency until the delay has been detected

This CL utilizes the existing, but unused, ability to set
different histogram thresholds for early and late delay
estimation. It does so by tuning the parameters for these.

On top of that, some corrections are added to correctly
handle resets and the use of the hysteresis thresholds.

We would like a merge of this issue to M71 as it addresses the aspect of choppy audio which has been raised as an issue both in M69 and M70.

The CL has been well tested both in Canary an offline and has been shown to perform as designed. The merge is considered safe as it is only active beneath a finch experiment and also has a dedicated kill-switch which can be used to deactivate the feature.

This bug requires manual review: DEPS changes referenced in bugdroid comments.
Please contact the milestone owner if you have questions.
Owners: benmason@(Android), kariahda@(iOS), kbleicher@(ChromeOS), govind@(Desktop)

Approving merge to M71 branch 3578 based on comment #4. Please merge ASAP. Thank you.

The CL has now been merged. The merging CL is
