This CL refactors and optimizes the 3-band split-filter in APM, which is a very computationally complex component. Beyond optimizing the code, the filter coefficients are also quantized to avoid denormals. The changes reduces the complexity of the split filter by about 30-50%. The CL has been tested for bitexactness on a number of aecdump recordings. (the CL also removes the now unused code for the sparse_fir_filter) Bug: webrtc:6181 Change-Id: If45f8d1f189c6812ccb03721156c77eb68181211 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/168189 Reviewed-by: Sam Zackrisson <saza@webrtc.org> Reviewed-by: Karl Wiberg <kwiberg@webrtc.org> Commit-Queue: Per Åhgren <peah@webrtc.org> Cr-Commit-Position: refs/heads/master@{#30592}
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.
