> Delay estimator wrapper API changes. This should finalize the changes to delay estimator making it work for multi-probe. > > The changes are summarized here: > > delay_estimator.* > ----------------- > Replaced assert() with correct error check. This is consistent with previous versions of the delay_estimator, i.e., to check for valid parameters where they are actually used and not high up in a wrapper layer. > > delay_estimator_internal.h > -------------------------- > Pulled out the far-end part of DelayEstimator struct and put it in DelayEstimatorFarend. The only common parameter is spectrum_size, which we store in both and thereby avoiding having a Farend pointer in DelayEstimator. > > delay_estimator_wrapper.* > ------------------------- > Added and updated descriptions. From Free(), Create(), Init() the far-end parts have been put in separate Farend versions. Same goes for the Process() which now has an AddFarSpectrum() version. > The flow of calls should be something like (in pseudo-code) > > far* = CreateFarend(history_size) > near* = Create(far, lookahead) > InitFarend(far) > Init(near) > while call ongoing > AddFarSpectrum(far, far_spectrum) > Process(near, near_spectrum) > end while > Free(near) > FreeFarend(far) > > delay_estimator_unittest.cc > --------------------------- > Added farend support setting up calls as mentioned above. > > aecm_core.* > ----------- > Cleaned up some lint warnings. > Added delay_estimator_farend pointer. Called Create(), Init() and Free() in above mentioned order. > If AddFarSpectrumFix() was not successfully done, we end and return -1. This is what we would have done for Process(). > > aec_core.* > ---------- > Cleaned up some lint warnings. > Added delay_estimator_farend pointer. Calls in proper order. Since we only use the delay estimator for logging there is no error handling. We only call Process() if AddFarSpectrum() was successful though. > > TEST=audioproc_unittest, trybots > BUG=None > > Review URL: https://webrtc-codereview.appspot.com/1076006 TBR=bjornv@webrtc.org Review URL: https://webrtc-codereview.appspot.com/1062008 git-svn-id: http://webrtc.googlecode.com/svn/trunk@3429 4adac7df-926f-26a2-2b94-8c16560cd09d
