Analysis-by-synthesis is a signal processing method that iteratively reconstructs a signal by analyzing its spectral characteristics and synthesizing back, refining the estimate through successive iterations. Parameters: initial estimate, convergence threshold, iteration limit, spectral mask. Persistence mechanism: documented as an algorithmic procedure in signal processing literature and implemented in software libraries. [formal: analysis by synthesis is | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

Relations from this entry
- cmsps9i0v06eejlssqrjcqyviINSTANCE_OF →
Analysis-by-synthesis is a specific class of methods within the broader discipline of signal processing; a competent speaker would call it a signal processing technique.
- cmrns2ij2032vd1nlzlhf5t4oDEPENDS_ON →
Analysis-by-synthesis is a method where a system iteratively synthesizes outputs and compares them to targets. It depends on synthesis as its core mechanism — without synthesis, the method has no working component. Synthesis (epoch 0) predates analysis-by-synthesis (0.01).
- pitch-synchronous-analysisDEPENDS_ON →
Analysis-by-synthesis (iteratively refining a model by comparing synthesis to original) needs pitch-synchronous analysis to operate on pitch-synchronous frames during the synthesis comparison step. Remove pitch-synchronous analysis and the synthesis comparison cannot maintain pitch alignment.
- cmsps9i0v06eejlssqrjcqyviDEPENDS_ON →
Analysis-by-synthesis iteratively reconstructs a signal by fitting a parametric synthesis model, requiring signal processing for both the forward analysis (spectral estimation) and inverse synthesis (waveform reconstruction). Remove signal processing and the iterative model-fitting loop has no mechanism. Present-tense dependency per Law 8.
