  "message": "[cherry pick] AGC2: retuning and large refactoring\n\n- Bug fix: the desired initial gain quickly dropped to 0 dB hence\n  starting a call with a too low level\n- New tuning to make AGC2 more robust to VAD mistakes\n- Smarter max gain increase speed: to deal with an increased threshold\n  of adjacent speech frames, the gain applier temporarily allows a\n  faster gain increase to deal with a longer time spent waiting for\n  enough speech frames in a row to be observed\n- Saturation protector isolated from `AdaptiveModeLevelEstimator` to\n  simplify the unit tests for the latter (non bit-exact change)\n- AGC2 adaptive digital config: unnecessary params deprecated\n- Code readability improvements\n- Data dumps clean-up and better naming\n\n(cherry picked from commit 980c4601e188a80bb435edf0c3e345899cd18c59)\nNOTRY\u003dtrue\n\nBug: chromium:1199259,webrtc:7494\nChange-Id: I4e36059bdf2566cc2a7e1a7e95b7430ba9ae9844\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/215140\nCommit-Queue: Alessio Bazzica \u003calessiob@webrtc.org\u003e\nReviewed-by: Jesus de Vicente Pena \u003cdevicentepena@webrtc.org\u003e\nCr-Original-Commit-Position: refs/heads/master@{#33736}\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/215782\nReviewed-by: Minyue Li \u003cminyue@webrtc.org\u003e\nCr-Commit-Position: refs/branch-heads/4472@{#7}\nCr-Branched-From: 3e0c60ba4ef28a9f26fe991e5eec3150402c7dd3-refs/heads/master@{#33644}\n",
