This reverts commit 9da3e177fd5c2236cc15fea0ee8933e1dd0d8f6d. Reason for revert: bug in ComputePitchPeriod48kHz() Original change's description: > RNN VAD: pitch search optimizations (part 1) > > 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%. > > Benchmarked as follows: > ``` > out/release/modules_unittests \ > --gtest_filter=*RnnVadTest.DISABLED_RnnVadPerformance* \ > --gtest_also_run_disabled_tests --logs > ``` > > Results: > > | baseline | this CL > ------+----------------------+------------------------ > run 1 | 24.0231 +/- 0.591016 | 23.568 +/- 0.990788 > | 370.06x | 377.207x > ------+----------------------+------------------------ > run 2 | 24.0485 +/- 0.957498 | 23.3714 +/- 0.857523 > | 369.67x | 380.379x > ------+----------------------+------------------------ > run 2 | 25.4091 +/- 2.6123 | 23.709 +/- 1.04477 > | 349.875x | 374.963x > > Bug: webrtc:10480 > Change-Id: I9a3e9164b2442114b928de506c92a547c273882f > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/191320 > Reviewed-by: Per Åhgren <peah@webrtc.org> > Commit-Queue: Alessio Bazzica <alessiob@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#32568} TBR=alessiob@webrtc.org,peah@webrtc.org No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: webrtc:10480 Change-Id: I2a91f4f29566f872a7dfa220b31c6c625ed075db Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/192660 Commit-Queue: Alessio Bazzica <alessiob@webrtc.org> Reviewed-by: Alessio Bazzica <alessiob@webrtc.org> Cr-Commit-Position: refs/heads/master@{#32581}
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
