WebRTC's AEC is integrated into most browsers, PulseAudio (https://www.freedesktop.org/software/pulseaudio/webrtc-audio...) and a variety of other systems.

Google, Mozilla and all the organizations that have collaborated on WebRTC have spent 7+ years tuning this component. Much like Opus versus AMR-WB, I doubt there is anything notably better in the proprietary software/hardware world.

The orgs that develop the WebRTC standard have spent years implementing and experimenting with nearly every algorithm that is available for each of the various components (resulting in Opus, AV1, WebRTC AEC, etc), combing research papers daily and often working with researchers directly.
