  "message": "RNN VAD: pitch search optimizations (part 3)\n\n`ComputeSlidingFrameSquareEnergies()` which computes the energy of a\nsliding 20 ms frame in the pitch buffer has been switched from backward\nto forward.\n\nThe benchmark has shown a slight improvement (about +6x).\n\nThis change is not bit exact but all the tolerance tests still pass\nexcept for one single case in `RnnVadTest,PitchSearchWithinTolerance`\nfor which the tolerance has been slightly increased. Note that the pitch\nestimation is still bit-exact.\n\nBenchmarked as follows:\n```\nout/release/modules_unittests \\\n  --gtest_filter\u003d*RnnVadTest.DISABLED_RnnVadPerformance* \\\n  --gtest_also_run_disabled_tests --logs\n```\n\nResults:\n\n      | baseline             | this CL\n------+----------------------+------------------------\nrun 1 | 22.8319 +/- 1.46554  | 22.087 +/- 0.552932\n      | 389.367x             | 402.499x\n------+----------------------+------------------------\nrun 2 | 22.4286 +/- 0.726449 | 22.216 +/- 0.916222\n      | 396.369x             | 400.162x\n------+----------------------+------------------------\nrun 2 | 22.5688 +/- 0.831341 | 22.4902 +/- 1.04881\n      | 393.906x             | 395.283x\n\nBug: webrtc:10480\nChange-Id: I1fd54077a32e25e46196c8e18f003cd0ffd503e1\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/191703\nCommit-Queue: Alessio Bazzica \u003calessiob@webrtc.org\u003e\nReviewed-by: Karl Wiberg \u003ckwiberg@webrtc.org\u003e\nCr-Commit-Position: refs/heads/master@{#32572}\n",
