TL;DR this CL improves efficiency and includes several code readability improvements mainly triggered by the comments to patch set #10. Highlights: - Split `FindBestPitchPeriods()` into 12 and 24 kHz versions to hard-code the input size and simplify the 24 kHz version - Loop in `ComputePitchPeriod48kHz()` (new name for `RefinePitchPeriod48kHz()`) removed since the lags for which we need to compute the auto correlation are a few - `ComputePitchGainThreshold()` was only used in unit tests; it's been moved into the anon ns and the test removed This CL makes `ComputePitchPeriod48kHz()` is about 10% faster (measured with https://webrtc-review.googlesource.com/c/src/+/191320/4/modules/audio_processing/agc2/rnn_vad/pitch_search_internal_unittest.cc). The realtime factor has improved by about +14%.

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
