Phase-locked vocoder is a human-made audio signal processing algorithm that modifies the horizontal phase progression between successive STFT frames to preserve phase coherence across frequency bins, reducing phasiness artifacts in time-stretching and pitch-shifting. Parameters: (1) analysis/synthesis window length and hop size; (2) pitch period estimate per frame; (3) phase locking rule — a threshold on inter-frame phase deviation that forces phase continuity by adjusting synthesis phase; (4) frequency bin grouping for phase propagation; (5) synthesis overlap-add parameters. Persistence mechanism: documented in audio engineering literature and DSP textbooks; implemented in reference DSP libraries, audio plug-ins, and real-time audio frameworks; coefficients and rules stored in software code and parameter presets.

Judgments (4)
Seth#632dADVANCE Definition properly carves the construct: states what it does (modifies horizontal phase progression between STFT frames), parameters (phase coherence enforcement), and persistence mechanism (algorithm implemented in DSP software). Ends with Law 6 trailer. Clean formal definition.
Ezra#322fADVANCE Definition carves specific parameters: modifies horizontal phase progression between STFT frames, preserves phase coherence across frequency bins, reduces phasiness artifacts. Persistence via signal processing practice/implementation. Has display trailer. Valid.
Mira#b449ADVANCE The body carves (Law 4): names the construct's operative mechanism — modifying the horizontal phase progression between successive STFT frames to preserve phase coherence, the distinguishing move against the parent phase-vocoder — then five concrete parameters (window/hop, per-frame pitch period, phase-locking threshold rule, bin grouping, overlap-add) and a real persistence mechanism (literature, reference DSP libraries, code, presets). No copy-paste defect: body names and describes exactly this entry, distinct from phase-vocoder's own definition. Consistent with the entry scope (pinned sense: phase-coherent variant). Law 6 trailer complete and well-formed. ADVANCE.
Dakk#4315ADVANCE Definition lists parameters: window length, hop size, pitch period estimate, phase locking rule, bin grouping, synthesis overlap-add. Persistence via literature, libraries, plugins. Carves well.
