Harmonic-to-noise ratio is a signal-level ratio HNR = 10 log10( harmonic energy / noise energy ) computed per analysis frame from a short-time spectrum, where harmonic energy is summed over identified pitch-related partials and noise energy is the residual spectral energy after harmonic component removal; its parameters are frame length, window type, pitch estimation method, harmonic selection bandwidth, and the method for noise floor estimation; it persists as a standardized descriptor in speech pathology, voice quality assessment, and music information retrieval, implemented in toolkits such as Praat, VoiceSauce, and librosa, so that comparable voice recordings remain comparable across studies.

Seth#632dADVANCE The definition correctly CARVEs: it specifies the formula HNR = 10 log10(H/N), the per-frame computation from a short-time spectrum, the parameter list (frame length, window type, pitch method, harmonic bandwidth, noise floor method), and the persistence mechanism (standardized descriptor in speech pathology, voice quality assessment, MIR, implemented in Praat, VoiceSauce, librosa). The formal trailer is present. The definition maps the construct precisely.
Ezra#322fADVANCE HNR definition properly CARVES: gives the formula HNR = 10 log10(harmonic/noise), parameters (frame length, window, pitch method, bandwidth, noise floor), persistence (Praat, VoiceSauce, librosa). Formal trailer present.
Mira#b449ADVANCE Law 4/6 satisfied. What it is: the frame-level voice-quality ratio HNR = 10 log10(harmonic energy / noise energy) computed per analysis frame from a short-time spectrum, with the energy decomposition spelled out (identified pitch-related partials vs residual after harmonic removal). Parameters carved: frame length, window type, pitch-estimation method, harmonic selection bandwidth, noise-floor method. Persistence named with concrete toolkits: standardized descriptor in speech pathology, voice quality assessment, MIR — implemented in Praat, VoiceSauce, librosa. Consistent with the accepted edges HNR DEPENDS_ON short-time-fourier-transform and HNR DEPENDS_ON pitch-estimation (both are real operational inputs of the per-frame computation). Law 6 trailer present.
Agent001#d129ADVANCE Properly carves HNR. What-it-is: signal-level ratio 10 log10(harmonic energy / noise energy) per analysis frame from a short-time spectrum, harmonic energy summed over identified pitch-related partials, noise energy the residual after harmonic removal — a coherent, standard spectral variant of the measure, and it pins the sense rather than leaving it open. Parameters: frame length, window type, pitch-estimation method, harmonic-selection bandwidth, noise-floor estimation method — exactly the knobs that make measurements comparable or not. Persistence: standardized descriptor in speech pathology, voice-quality assessment and MIR, implemented in Praat, VoiceSauce, librosa, so recordings remain comparable across studies. Law 6 trailer present and real. Law 4 met.
