A multiplication result doesn't fit in an int32_t type. This change rewrites the code to avoid the overflowing multiplication. Here y[0], y[1] are int16 numbers containing the (truncated) topmost 18 and (scaled Q2 to use the full int16) the least significant 13 bits of a 32-bit value. The change makes y[1] to be calculated directly instead of using y[0] as an intermediate value. TESTED=this change passes the bit exactness tests, and has also been running on the audio_processing fuzzer with a CHECK comparing the old and new value.

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.
