RNN VAD: GRU layer optimized Using `VectorMath::DotProduct()` in GatedRecurrentLayer to reuse existing SIMD optimizations. Results: - When SSE2/AVX2 is avilable, the GRU layer takes 40% of the unoptimized code - The realtime factor for the VAD improved as follows - SSE2: from 570x to 630x - AVX2: from 610x to 680x This CL also improved the GRU layer benchmark by (i) benchmarking a GRU layer havibng the same size of that used in the VAD and (ii) by prefetching a long input sequence.

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.
See here for instructions on how to get started developing with the native code.
