AEC3: Delay estimator uses bandpass filtered signal with downsampling factor 8 Letting the delay estimator operate at a sampling frequency of 2 kHz with audio between 0 and 1 kHz makes it sensitive to noisy environments. This CL bandpass filters the 16 kHz signal before downsampling to 2 kHz in a way that the downsampled 2 kHz signal contains audio between 1 and 2 kHz. It also sets downsampling factor 8 as default which significantly reduces computational complexity.

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 http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
