  "message": "Disable AudioOptions in Scream and L4S BWE integration tests\n\nWebRtcVoiceEngine::ApplyOptions disables software noise suppression,\necho cancellation, and auto gain control on iOS (WEBRTC_IOS) while\nleaving them enabled by default on other platforms. In PeerScenario BWE\nintegration tests using TestAudioDeviceModule::CreatePulsedNoiseCapturer,\nthis platform difference caused un-attenuated pulsed noise on iOS to\ndrive Opus and Audio Network Adaptor to higher bitrates, increasing\nbottleneck queue delay in\nScreamTest.AudioOnlyBothDirectionsLinkCapacity40To90KbpsRtt200ms\n(causing ICE STUN ping RTTs around 653 ms vs. the 600 ms limit) and\npreviously requiring CcFbSendRateAdaptation to be disabled on iOS.\n\nExplicitly disable echo_cancellation, auto_gain_control,\nnoise_suppression, and highpass_filter in SendMedia and\nCcFbSendRateAdaptation so all platforms run with identical audio\nprocessing settings, relax the upper RTT bound in\nAudioOnlyBothDirectionsLinkCapacity40To90KbpsRtt200ms from 600 ms to\n700 ms, and re-enable CcFbSendRateAdaptation on iOS.\n\nBug: webrtc:42225697, webrtc:447037083\nChange-Id: I36660d614cc67b17c9cc56ac610fb332f243c8d6\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/516140\nReviewed-by: Erik Språng \u003csprang@webrtc.org\u003e\nCommit-Queue: Per Kjellander \u003cperkj@webrtc.org\u003e\nCr-Commit-Position: refs/heads/main@{#49263}\n",
