There were a couple operations in the mixer which touched AudioFrame data() and mutable_data() getters in a hot loop. These getters have a if (muted) conditional in them which led to inefficient code generation and execution. Profiled using Google Meet with 6 audio-only speaking participants. Meet uses 3 audio receive streams.

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
