Fix FFT output size to avoid incorrect band energy computation The FFT output buffers sizes in SpectralFeaturesExtractor have been reduced from N to N/2+1, where N is the audio frame size. This is required since ComputeBandEnergies() currently calls ComputeBandCoefficients() indicating a higher value for max_freq_bin_index, hence polluting the higher bands with unwanted energy (coming from the symmetric conjugate copy of the Fourier coefficients).

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.
