This CL replaces KissFFT with PFFFT for the spectral features computation. Remarks: - Extra FFT output vector copy eliminated - Scaling and windowing merged into a single vector for efficiency - Nyquist frequency hack to keep the iteration in BandFeaturesExtractor::ComputeSpectralCrossCorrelation simple Bug: webrtc:9577, webrtc:10480 Change-Id: I436563bd257f66a243f5402be270ffcf859bd184 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/130221 Commit-Queue: Alessio Bazzica <alessiob@webrtc.org> Reviewed-by: Per Åhgren <peah@webrtc.org> Cr-Commit-Position: refs/heads/master@{#27536}
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.
