The audio mixer has a subcomponent called FrameCombiner, which uses an AudioProcessing instance as a limiter. The limiter smoothly increases the volume to avoid causing clipping. The limiter was created in a default configuration causing the ResidualEchoDetector submodule of AudioProcessing to be activated. That submodule operates in the band-split domain (see AudioProcessingImpl::ApmSubmoduleStates::RenderMultiBandSubModulesActive()). There is a goal to remove the (expensive and unnecessary) band-splitting from AudioMixer. This change helps accomplish that. (It can't be done yet, because the actual limiter sub-component of APM also operates in the band-split domain).

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
