During pitch search in the RNN VAD, we calculate auto correlation. Before this CL, we computed kNumInvertedLags12kHz=147 dot products of vectors with kBufSize12kHz-kMaxPitch12kHz=240 elements. This was the most time consuming step of the new VAD. This CL makes the computation happen in frequency domain. Profiling shows a 3x speed increase. In future, we can try using a more efficient FFT and to reduce the FFT length to some of e.g. 400, 405, 432. # For minimal Clang plugin check change.

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.
Authoritative list of directories that contain the native API header files.
