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).
