Merge audio_processing changes. R=aluebs@webrtc.org, bjornv@webrtc.org BUG= Review URL: https://webrtc-codereview.appspot.com/32769004 git-svn-id: http://webrtc.googlecode.com/svn/trunk@7893 4adac7df-926f-26a2-2b94-8c16560cd09d 11 年前
RNN VAD: GRU layer optimized Using VectorMath::DotProduct() in GatedRecurrentLayer to reuse existing SIMD optimizations. Results: - When SSE2/AVX2 is avilable, the GRU layer takes 40% of the unoptimized code - The realtime factor for the VAD improved as follows - SSE2: from 570x to 630x - AVX2: from 610x to 680x This CL also improved the GRU layer benchmark by (i) benchmarking a GRU layer havibng the same size of that used in the VAD and (ii) by prefetching a long input sequence.

Conversational Speech dataset Publicly available dataset of conversational speech audio recordings. This CL includes the following: - README.md: dataset description file, it also includes the scripts - *.wav.sha1: hash files for each audio track in the dataset The overall size of the wav files is ~36MB. The primary intended use of this dataset is in combination with the conversational speech tool (see https://chromium.googlesource.com/external/webrtc/+/master/webrtc/modules/audio_processing/test/conversational_speech/), using which longer recordings with custom turn switch timing can be created.

Increased high frequency transparency Avoid excessive echo suppression in frequencies above 2 kHz when there is a dominant nearend. Calls with clock drift will not be affected by this change as they tend to have less accurate linear filters.

Delete voice_detection() pointer to submodule The new configuration path is via AudioProcessing::ApplyConfig and AudioProcessing::GetStatistics. ApmTest.Process passes with unchanged reference files if audio_processing_impl would initialize the VAD with VoiceDetection::kLowLikelihood instead of kVeryLowLikelihood. This was verified by testing this CL with that modification.
